The petrochemical industry does not forget about motorists, producing various additives to extend the life of vehicles. The appearance of miracle supplements was received ambiguously by domestic car enthusiasts. They helped some avoid expensive repairs, while others are sure they threw money down the drain. Not in all cases, additives can help out the car owner, especially if the car’s engine is completely “killed.”

Most often, additives are useful preventive maintenance or minor repairs to a still working engine. In addition, today the field of activity of additives is increasingly narrowing, as is usually written in the attached instructions. Unfortunately, our people do not have time to thoroughly study the manufacturer’s recommendations, which is why many do not get the expected effect. This review includes the best additives for different types of engines. The rating was compiled taking into account reviews of domestic car owners.

The best additives for gasoline engines

A distinctive feature of gasoline engines is the high temperature in the combustion chambers. Therefore, additives must be heat-resistant, as are the coatings and films they form.

5 WINDIGO Set for internal combustion engines with microceramic additive for 3-4 liters of oil

High impact efficiency
Country: Germany
Average price: 3990 rub.
Rating (2019): 4.5

An unusual two-component additive is equally suitable for gasoline and diesel engines. The task of the first component (Motor-Cleaner) is to give mobility to all kinds of deposits on the walls of channels and engine parts. It also effectively cleans the oil rings on the pistons and stops any oxidation processes. After treatment, the additive is removed along with the engine oil, and a new one is poured into the engine (with the filter replaced). In this case, the new lubricant must be thoroughly mixed with the second WINDIGO component containing nanoceramic particles (0.15 microns).

After letting the engine idle, you can begin normal operation. This treatment at least doubles the life of the motor. The additive is effective for 60 thousand km, after which the owners, as a rule, repeat the testing. The effect of using WINDIGO is most clearly manifested in the increase in engine dynamics and reduction in fuel consumption (more than 10%). Owners also note the disappearance of unnecessary noise and vibration, as well as a drop in the operating temperature of the oil, which indicates a significant reduction in friction forces. In the reviews left, the majority considers the overall reduction in car maintenance costs to be the best result of the additive.

4 RVS Master Engine Ga3

Better resource increase
Country: Finland
Average price: 1512 rub.
Rating (2019): 4.8

Different compression in the cylinders and increased fuel consumption are not yet a reason to overhaul the engine. In any case, car owners who promptly filled the engine neck with the RVS Master Engine Ga3 additive managed to avoid thousands of expenses. The metal conditioner forms a coating in places of wear, the strength of which is several times greater than galvanic chrome plating. By adding an additive to the oil, the owners of tired “engines” had no illusions when preparing money for major repairs.

Imagine their surprise when, after treatment, amazing (there is no other way to say it!) changes occurred. According to reviews, compression has leveled out across the cylinders and reached the levels of a new car. The oil pressure also increased and its consumption decreased. Excessive vibration and strange noises inside the engine are gone, and fuel consumption has significantly decreased (from 10 to 15%!). One treatment gives the engine about 120 thousand km of additional resource, while no one prohibits the reuse of the additive. The main thing is to apply it on time.

3 ER-5

Buyer's choice
Country: UK
Average price: 920 rub.
Rating (2019): 4.8

The effectiveness of this additive for gasoline engines was experimentally tested in the factory laboratory of the VAZ automobile concern. As a result of measurements, a decrease in the forces arising in friction pairs was recorded. With timely use, the geometry of the cylinder-piston group is restored - shells and production are effectively restored due to the free atomic components of the additive.

Owners of cars with high mileage note the undoubted benefits of exposure to this substance. In the reviews, many express outright surprise, because... It was possible to postpone the upcoming major overhaul for quite a long time. Efficiency largely depends on the condition of the motor components at the time of the first treatment. The additive is added to the engine oil at each regular oil change. Constant use stops the "guzzling" of lubrication, increases power and compression. The only drawback is that for modern high-performance engines this additive is ineffective.

2 Liqui Moly CeraTec

The most reliable engine protection
Country: Germany
Average price: 1381 rub.
Rating (2019): 4.8

Reliable protection for a gasoline engine is provided by the German additive Liqui Moly CeraTec. The additive is based on a molybdenum-organic complex, which is supplemented with ceramic microparticles. Regular use of the composition can increase the wear resistance of metal parts and mechanisms. The anti-friction effect is achieved by smoothing out microscopic irregularities inside the engine, which has a beneficial effect on sliding. The duration of action of the additive is maintained for 50 thousand kilometers. After adding the composition to the oil, there is a decrease in lubricant and gasoline consumption, and the power unit runs quieter.

Domestic motorists in reviews indicate such strengths of the Liqui Moly CeraTec additive as economical engine operation, increased service life, and long-lasting action. Among the disadvantages, the high price is noted; it is not always possible to improve engine performance.

The most popular types of engine additives

What additives are currently considered the best for the engine? There are a few points worth paying attention to here.

1. First of all, it is necessary to determine the purpose of the purchased additive. If the engine is “crying tears of oil,” then you should not increase its compression. It is better to turn your attention to special sealants.
2. The problem of noise and smoke can also be solved with the help of engine additives. You just need to choose the appropriate option for your motor. It is necessary to take into account not only the type of power unit (petrol, diesel), but also the oil base (mineral water, semi-synthetic, synthetic).
3. When diagnostic studies show that the power unit does not have many engine hours left to live, then remetallic additives can delay major repairs. They contain metal particles that form a durable layer on the surface of worn parts. As a result, the gaps are reduced, the engine starts better, and it gains traction. But the effect of remetallizants is limited to several tens of thousands of kilometers.

1 XADO Revitalizant EX120, 9 ml tube

The most effective additive
Country Ukraine
Average price: 802 rub.
Rating (2019): 5.0

The undisputed leader among revitalizant additives. The active substance is manufactured on the basis of Soviet military developments (successful tests of XADO were carried out under real conditions in Afghanistan back in the USSR). The main condition for use is that the engine must have a service life of 2100 km. This is exactly how much you need to drive to fully protect the engine. First, every 200 km you will have to squeeze 1 tube into the oil filler neck of the engine, and then operate the car quietly until the next oil change.

Reviews from owners confirm that it is possible to avoid major engine repairs. True, not everyone manages to complete the processing on time, and counterfeit products on the market spoil the reputation no less. After successful treatment, compression is restored, the engine runs quieter and without unnecessary vibrations. Worn areas of parts are restored from metal-ceramic components of the additive (the place of impact is determined at the molecular level - the build-up occurs in areas where excessively high friction forces occur). Further operation can proceed as usual. The safety margin after such treatment is about 50 thousand km, but timely repetition of the procedure will prolong the delay in major repairs of the internal combustion engine for some more time.

The best additives for diesel engines

Over time, diesel engines develop compression problems and increase noise and smoke. When purchasing additives, you should find out the possibility of their use in diesel engines.

5 FENOM FN 710

Optimal recovery characteristics
Country Russia
Average price: 240 rub.
Rating (2019): 4.4

The metal reconditioner FENOM FN 710 has helped out more than one hundred car owners of cars with high mileage who were already preparing to take their car for major engine repairs. In the last hope of delaying the inevitable, they added a domestic additive when changing the oil. Imagine the surprise when, after 1000 km, positive changes began to appear. Oil consumption has seriously decreased, the engine has reduced noise and vibration when idling. Such reviews are not isolated, and you can find them not only on the Internet.

Despite the budget price segment, the additive has a fairly effective effect on a “tired” engine. It will not return it to its original characteristics, but it is quite capable of maintaining the FENOM FN 710 in normal working condition. In order for the product to really help, you only need to follow two important recommendations - purchase the original product and carry out the treatment in a timely manner. When there are a couple of thousand kilometers left until the last stop of the engine, even the most expensive additive is powerless.

4 RESOURCES DIESEL

Best Engine Rebuild
Country Russia
Average price: 373 rub.
Rating (2019): 4.6

To restore worn-out diesel engines, a domestic manufacturer offers RESURS DIESEL remetallisant. The additive is designed to be added to new engine oil when replacing the lubricant and filter element. The composition is resistant to centrifuges and turbines, preventing dry friction during cold starts or under heavy loads. The manufacturer promises to increase the engine service life up to 20 thousand km, and the turbocharger up to 1 year. Among the beneficial properties of the remetallizant, one should note a reduction in oil waste (up to 5 times), fuel economy (up to 10%), and an increase in compression (up to 40%). It is recommended to use the additive when the car's mileage is more than 60 thousand km.

Users managed to appreciate the quality of the RESURS DIESEL additive. In many cases, diesel engines become more powerful, run quieter, and start better. Some car owners are skeptical about the capabilities of the additive, because they have not found any noticeable improvements.

3 AC-627

Affordable price
Country Russia
Average price: 220 rub.
Rating (2019): 4.7

The domestic company ASTROhim has created the most affordable additive for AC-627 engines. It is intended for adding to oil (volume up to 6 l) of diesel and gasoline engines. It is recommended to use the new composition in cars with high mileage. First of all, the beneficial effect of the additive is manifested by eliminating gaps that were the result of natural wear of parts. This is especially important for sealing pistons in diesel engine cylinders. The composition helps restore working compression in both cars and trucks, as well as in agricultural, special, and construction equipment. The additive can be used with any type of lubricant; during operation, the composition maintains an optimal balance of engine oil.

Domestic car owners speak positively about the availability and capabilities of the AC-627 additive. It quickly increases compression, improving diesel starting and increasing its power.

2 SUPROTEC. Tribological composition "Active" (Active Diesel)

Complex effect on the engine. “Healing” friction defects
Country Russia
Average price: 1200 rub.
Rating (2019): 4.8

A unique tribo composition of finely dispersed mineral powders of a certain composition and strictly selected fractionation is capable of gradually forming a layer resistant to friction and wear on the rubbing surfaces of the engine. Unlike conventional oil additives, which simply increase slip and must be present in the lubricant constantly, it is recommended to use it either once or periodically, but at long intervals. In addition, the positive effect of treatment with the drug is manifested in several directions at once: first, carbon deposits are removed from engine parts, which leads to improved operating conditions and reduced wear, then a protective nanofilm with a low friction coefficient is formed, and at the same time, scratches that appear during operation are smoothed out engine.

Thus, the tribotechnical additive “Active Diesel” is an effective “cure” for an engine that already has a significant degree of wear, but is still quite lively: there is no critical oil consumption, high crankcase gas pressure and compression in the cylinders reaches at least 8 kg/ cm 2. The owner of such a car can count on a significant improvement in its performance. Judging by numerous reviews, it is expressed in a noticeable reduction in fuel consumption and engine noise, an increase in its service life, an increase in the car’s responsiveness to the pedal and acceleration dynamics. But the additive most likely will not save a badly worn “heart,” and the manufacturer honestly warns customers about this.

1 Bardahl Full Metal

The most advanced composition
Country: Belgium
Average price: 1650 rub.
Rating (2019): 4.9

The Belgian manufacturer introduced the most modern developments in the Bardahl Full Metal additive. The composition helps extend the life of a diesel engine with severe wear. Thanks to the patented Bardahl Polar Plus technology, it was possible to increase the adhesion of the oil film. Even after standing in the cold for a long time, the oil remains on the parts, reducing the clearances in the piston group. The oil film also reduces friction in loaded components such as the crankshaft and camshaft. The use of the additive has a positive effect on fuel economy and oil consumption. The concentration of soot and burning in the exhaust gases of diesel cars decreases, and the smoke becomes lighter. It should be noted that the composition does not contain solid particles, so the oil filter and internal cavities of the engine do not become clogged.

In reviews, car enthusiasts praise the Bardahl Full Metal additive for improving diesel engine starting, increasing its power, and reducing smoke. The main disadvantage of the additive is its high price.

Best Sealing Additives

Any engine develops oil leaks over time. It is best to solve this problem by replacing rubber products. But in some cases, it will be faster and cheaper to introduce sealant additives.

5 AIM-ONE SL-410

The fastest sealant additive
A country: Japan (made in China)
Average price: 214 rub.
Rating (2019): 4.5

The best choice for solving the problem of increased oil consumption or leakage through gaskets is the universal product AIM-ONE SL-410. This sealing additive is excellent for both gasoline and diesel engines, so it can be used not only in passenger cars, but also in special equipment. At the same time, the sealant is consumed economically and one bottle is enough to solve standard problems of restoring performance and further protecting the engine.

To carry out repair work with the presented product, no additional skills are required. Just follow the instructions in the operating instructions and the problem will be solved. Already after 300 km of engine operation, the additive will manifest itself, completely stopping oil leaks, and thereby allowing you to continue operating the car without expensive repairs. In reviews, users note the effective effectiveness of this additive and confirm its ability to completely eliminate leaks.

4 EUROL Engine Stop Leak

High quality components. Guaranteed result
Country: Netherlands
Average price: 750 rub.
Rating (2019): 4.8

When engine oil leaks through gaskets or oil seals, as well as reduced efficiency of oil scraper rings on valve guide rods, it will be useful to use the EUROL Engine Stop Leak additive. Sooner or later, drying out of the elastomers leads to a violation of the seal, but opening the engine just to replace them is not always advisable. The additive acts softly and does not have any solid inclusions. It is poured directly into the oil filler neck, after which the engine should be allowed to run for better distribution of the active substance in the system.

The product does not act instantly - although the substance has powerful penetrating abilities, the seals must still swell, and this takes some time. In this case, the treatment will be more effective if the car is in use. The gaskets not only regain their original size, but their elasticity also returns, which is much more important for the resuscitation of seals. Owners of used cars in their reviews confirm the effectiveness of EUROL Engine Stop Leak - the additive really restores the tightness of the oil system.

3 AC-625

Best price
Country Russia
Average price: 190 rub.
Rating (2019): 4.8

The domestic additive AC-625 will help eliminate engine oil leaks quickly and cheaply. It is suitable for both gasoline and diesel engines with turbocharging. The product effectively combats lubricant leaks by softening rubber gaskets and seals. The sealant does not have any side effects on the operation of the engine oil, and it will prevent the occurrence of leaks in the power unit until replacement. The volume of one bottle is enough to mix with 6 liters of oil. It is best to introduce the additive when replacing the lubricant and filter, but only after the engine has warmed up to operating temperature. The composition can be used with any type of motor oil.

Car owners in reviews mention such advantages of the domestic AC-625 additive as availability and efficiency. Among the disadvantages, users note the fragility of the sealing.

2 Liqui Moly Oil-Verlust-Stop

The most effective oil line restoration
Country: Germany
Average price: 720 rub.
Rating (2019): 4.9

A quick and effective remedy for eliminating leaks in engine oil lines was created by Liqui Moly specialists. The Oil-Verlust-Stop additive copes not only with cracks in hoses, but also makes other rubber parts (oil seals, gaskets) more elastic. The use of the composition also has a beneficial effect on reducing engine noise and smoke during operation. This is due to the improved properties of valve stem seals and hydraulic compensators. The composition can be used in gasoline and diesel engines; the volume of the bottle is enough to mix with 3-4 liters of motor oil. The first signs of restoration of tightness should be expected after 600-800 km.

Experienced drivers have noticed a number of positive aspects from using the Oil-Verlust-Stop additive. Oil leaks are eliminated, noise and smoke are reduced, and the durability of oil pipelines is increased. Unfortunately, not all defects in oil hoses can be eliminated.

1 Hi-Gear "Stop Leak" for the engine

Better sealing of seals and gaskets
Country: USA
Average price: 540 rub.
Rating (2019): 5.0

An effective additive for eliminating oil leaks in the engine is the Hi-Gear "Stop Leak" composition. The manufacturer has patented a special polymer formula that stops the leakage of engine oil through oil seals and gaskets. The additive is introduced into the lubricating fluid, where it is distributed evenly. Together with the oil, the unique composition penetrates through microscopic holes and cracks. Upon contact with air, the additive polymerizes, thereby restoring engine tightness. The hardened part of the additive ensures reliable connections for a long time. The additive molecules remaining in the oil will work until scheduled maintenance, preventing new leaks from occurring.

Motorists speak positively about the performance of the product, “Stop Leak” is especially helpful when the front and rear crankshaft seals are worn out.

Experienced drivers know that some engine problems can be fixed without resorting to repairs. It is not necessary to have special skills. The modern market offers a special product - additives for engine restoration. Their use will not cause difficulties even for a beginner. Simply adding an engine is enough. There are a number of products from different manufacturers. All of them are aimed not only at restoring the life of the internal combustion engine, but also at further protecting it.

Using additives you can restore engine performance.

How do engine additives work?

All engine rebuilding additives work on a similar principle. Despite the complexity of the chemical and physical processes taking place, in practice everything looks simple. Almost all products have catalyst properties. That is, they accelerate the crystallization process that takes place on the surface of parts that constantly rub during operation. After adding the additive, all components are covered with a thin protective film, which takes the entire load. This also prevents the parts from coming into direct contact with each other, which keeps friction to a minimum.

Restoring engine additives, when used in combination, improve the crystal lattice of the metal. Also, some products increase compression and help decarbonize. All manufacturers use their own technologies and various materials as the main active substances.

What are engine additives made of?

As a rule, engine repair and restoration additives are added to engine oil. At the same time, depending on the needs, different products are chosen that differ in composition. Based on the active components of the most popular quality manufacturers, three groups are distinguished:

In each of the presented groups there are real market giants, offering a range of different products for a specific type and size of engine. When choosing, be sure to pay special attention to compatibility.

Features of application

At the moment, engine restoration with additives is possible in two options:

• additive to motor oil.

These methods are individual for each individually selected additive and depend primarily on what exactly you want to do. Each supplement addresses multiple causes. There are no universal remedies. It is also worth remembering that you can add several products at the same time. But before that, be sure to clarify and check their compatibility not only with the fuel and oil used, but also with each other.

The further operation of your car’s engine will depend on the correct selection and use of a reducing additive. Therefore, you should choose not according to the declared qualities in advertising and slogans, but according to the results actually proven in practice. Restoring an engine with additives is a complex process. The results will not be visible immediately, but after a short run of at least 100 - 200 kilometers. If you have chosen the right products and used them in accordance with the instructions for use, the improvements will be noticeable to the naked eye. Do not forget that regular use of supplements will help maintain the results.

Efficiency of restorative additives

Both on the Internet and in life, disputes often arise among drivers about the effectiveness of using repair and restoration additives for engines. Proponents are full of praise for their use, claiming that their car has literally been “resurrected.” Opponents of using supplements say they will cause more problems than they are worth. Negative reviews arise in most cases due to incorrect application. To finally answer the question of effectiveness, we present the results of one study from independent car enthusiasts.

To restore the engine by adding additives to the oil, they took an already fairly battered VAZ-2110. At the beginning of the experiment, we measured indicators that looked like this:

• power – 61 l. With.;
• compression – 8 kgf/cm2.

After this, an additive was added to the oil. This was followed by a run of 2000 kilometers. Immediately a repeat measurement was made, which showed the following results:

• power – 74 l. With.;
• compression – 12 kgf/cm2.

It turns out that after adding a reducing additive, the performance increased by 20 and 50 percent, respectively. A comprehensive study found a 60% reduction in the impact of friction. After such an experiment, the question of their effectiveness should disappear. The experiment was carried out not in ideal laboratory conditions, as is usually the case, but in the realities of city life.

The best additives for engine restoration

To understand which additives are best to use to restore an engine, you can make a rating of the most effective, time-tested companies. Their products are used by many car enthusiasts.

RVS Master

RVS additives are the most effective when used regularly. They require the least amount of additional additives for maximum results. They are considered premium additives. This is largely due to the higher price than its analogues. But the final cost of constant use is much cheaper. This is also due to the fact that the cycle between changes of the substance is the longest among all additives - at least 60,000 kilometers, while for the rest this level is the maximum.

XADO

Also often used to rebuild an engine. The company's products have been tested by many car enthusiasts and are recommended for beginners. All problem areas of your car's engine will be filled with cermets. The effect of the additive is noticeable after 1000 kilometers. The price is in the average range, as a result of which the cycle between additive changes is significantly shorter than that of RVS.

Suprotek

Suprotek restorative additives entered the market not so long ago. They are similar in quality to RVS Master, but still a little inferior. The price is also high, since the manufacturer tried to make the most universal product for all types of loads.

Rimet

Rimet is developing new technologies for regenerative additives to be added to motor oil. The products of this company are the best among all budget options. But cheap doesn't mean bad. Due to the introduction of the latest technologies into production, the quality of additives does not suffer. The only negative is the rather narrow focus of individual additives. You should choose them extremely carefully.

Bottom line

As a result, we can say that it is possible to restore the engine with the help of additives. To achieve your goals, you need to choose the right additive, taking into account compatibility. Regular and correct use will definitely show improvement and help restore your car's engine performance without repairs.

Anti-friction additives allow you to significantly increase the life of engine oil, as well as improve its performance. In addition, additives enhance the protective and lubricating properties of the oil. The third function that this composition performs is additional cooling of the rubbing parts in the engine. Thus, the use of anti-wear additives makes it possible to increase the service life of the engine, protect its individual components, increase the power and throttle response of the engine, and reduce fuel consumption.

Antifriction additives are a special chemical composition that allows you to achieve oil savings, increase compression in the cylinders, and generally extend engine life.

Such agents are called differently - remetallizants, friction reducing additives or antifriction additives. Manufacturers promise to use them to increase engine power, reduce friction of its moving parts, reduce fuel consumption, increase engine life, and reduce exhaust toxicity. Many remetallizing additives can also “heal” wear on the surfaces of parts.

Description and properties of antifriction additives

Any motor oil in a car engine performs three functions - lubricates, cools and cleans surfaces of rubbing parts. However, during the operation of the motor, it gradually loses its properties for natural reasons - due to operation at high temperatures and under pressure, as well as due to gradual clogging with small elements of debris or dirt. Therefore, fresh oil and oil that has been in the engine for, for example, three months are already two different compositions.

The new oil initially contains additives designed to perform the functions listed above. However, depending on their quality and durability, their lifespan can vary significantly. Accordingly, the oil loses its properties (although the oil can lose its properties for other reasons - due to an aggressive driving style, using the car in dirt and/or dusty conditions, poor oil quality, and so on). Accordingly, special wear reducing additives both engine elements and the oil itself (increasing the duration of its use).

Types of antifriction additives and where to use them

The additives mentioned above include various chemical compounds. This could be molybdenum disulfide, microceramics, air conditioning elements, so-called fullerenes (a carbon compound that operates at the nanosphere level) and so on. Additives may also contain the following types of additives:

• polymer-containing;
• layered;
• metal cladding;
• friction geomodifiers;
• metal conditioners.

Layered additives used for new engines, and are intended for grinding components and parts together. The composition may include the following components - molybdenum, tungsten, tantalum, graphite, etc. The disadvantage of this type of additive is that they have an unstable effect, which also almost completely disappears after the additive leaves the oil. The result may also be increased corrosivity of the exhaust gases of an engine in which layered additives were used.

Metal cladding additives(friction remetallizers) are used to restore microcracks and minor scratches on engine components. They contain microparticles of soft minerals (most often copper), which mechanically fill all the roughness. One of the disadvantages is that the forming layer is too soft. Therefore, for the effect to be permanent, you need to use these additives on an ongoing basis - as a rule, at every oil change.

Friction geomodifiers(other names - repair and restoration compositions or revitalizers) are made on the basis of natural or synthetic minerals. Under the influence of friction of the moving parts of the motor, a temperature is formed, due to which mineral particles combine with the metal, and a strong protective layer is formed. The main disadvantage is that due to the resulting layer, temperature instability appears.

Metal conditioners consist of chemically active substances. These additives make it possible to restore anti-wear properties by penetrating the surface of metals, restoring its anti-friction and anti-wear properties.

Which anti-wear additives are best to use?

But you need to understand that such inscriptions on packages with additives are actually more of a marketing ploy, the purpose of which is to attract buyers. As practice shows, additives do not provide miraculous transformations, but they still have some positive effect, and in some cases it makes sense to use such an anti-wear agent.

Beware of additives that contain chlorinated paraffin. This product does not restore the surface of parts, but only thickens the oil! And this leads to clogging of the oil channels and excessive wear of the engine!

A few words about molybdenum disulfide. It is a popular anti-wear additive used in many lubricants used in automobiles, e.g. Another name is “friction modifier”. This composition is widely used, including by manufacturers of antifriction additives for motor oil. So, if the packaging says that the additive contains molybdenum disulfide, then such a product is definitely recommended for purchase and use.

Disadvantages of using antifriction additives

There are also two disadvantages of using antifriction additives. The first is that in order to restore the working surface and maintain it in normal condition, the additive must be constantly present in the oil in the proper concentration. As soon as its value drops, the work of the additive immediately stops, and in addition, this can lead to significant clogging of the oil system.

The second disadvantage of using antifriction additives is that the rate of oil breakdown, although reduced, does not stop completely. That is, hydrogen from the oil continues to flow into the metal. This means that hydrogen destruction of the metal takes place. However, it is worth noting that the benefits of using antifriction additives are still greater. Therefore, the decision on whether to use these compounds or not rests entirely with the car owner.

In general, we can say that the use of antifriction additives makes sense if their add to inexpensive or medium quality oil. This follows from the simple fact that the price of anti-friction additives is often high. Therefore, in order to extend the life of the oil, you can buy, for example, inexpensive oil and some kind of additive. If you use high-quality motor oils, for example, or, then using additives with them hardly makes sense, they are already present there (although, as they say, you can’t spoil the porridge with oil). So whether to use antifriction additives in the oil or not is up to you to decide.

The method of using additives for the vast majority is identical. It is necessary to pour the composition from a canister into the engine oil. In this case, it is important to observe the required volume (usually it is indicated in the instructions). Some formulations, for example, Suprotec Active Plus, need to be filled twice, in particular, at the beginning of the oil’s operation, and after driving about one thousand kilometers. In any case, before using any additive, be sure to read the instructions for its use and follow the recommendations given there! We, in turn, will provide you with a list of popular brands and a brief description of their action so that you can choose the best anti-friction additive.

Rating of popular additives

Based on numerous reviews and tests from the Internet conducted by various car owners, a rating of anti-friction additives that are common among domestic motorists was compiled. The rating is not of a commercial or advertising nature, but only aims to provide the most objective information about the various products currently presented on the shelves of auto stores. If you have had a positive or negative experience using this or that anti-friction additive, do not hesitate to speak in the comments.

Tests conducted by specialists from the authoritative domestic publication Za Rulem showed that the Bardal Full Metal anti-friction additive shows some of the best results compared to similar compounds. That's why she gets first place in the ranking. Thus, the manufacturer positions it as a new generation additive based on the use of C60 fullerenes (carbon compounds) in its base, which can reduce friction, restore compression and reduce fuel consumption.

Real tests really showed excellent efficiency, although not as significant as the manufacturer indicates. The Belgian additive in Bardal oil really reduces friction, and hence the power increases and fuel consumption decreases. However, two drawbacks are noted. The first is that the positive effect is short-lived. So, the additive must be changed at every oil change. And the second drawback is its high cost. Therefore, the question arises about the advisability of its use. Here each car owner must decide individually.

Bardahl Full Metal anti-friction additive is sold in a 400 ml can. Its article number is 2007. The price of this can as of the summer of 2018 is about 2,300 rubles.

SMT2

A very effective additive designed to reduce friction and wear, as well as prevent scuffing of piston parts. The SMT metal conditioner is positioned by the manufacturer as a product capable of reducing fuel consumption, reducing exhaust smoke, increasing the mobility of piston rings, increasing engine power, increasing compression, and reducing oil consumption.

Real tests have shown its good effectiveness, so the American anti-friction additive SMT2 is fully recommended for use. A positive effect is also noted in the restoration of the surfaces of parts, that is, tribotechnical processing. This is explained by the presence of elements in the additive that “heal” irregularities. The action of the additive is based on the adsorption of active components with the surface (quartz fluorocarbonates, esters and other surfactants are used as these components).

The only disadvantage of this product is that it can rarely be found on sale. And depending on the condition of the engine, the effect of using the SMT additive, in particular the 2nd generation synthetic metal conditioner SMT-2, may not be different at all. However, this can be called a conditional disadvantage. note that It is NOT recommended to pour into the gearbox (especially if it is an automatic), only into the engine!

Sold in a 236 ml canister. Product code - SMT2514. The price for the same period is about 1000 rubles. Also sold in 1000 ml packaging. Its article number is SMT2528. The price is 2800 rubles.

A completely effective additive, which is positioned as a product that is guaranteed to work for 50 thousand kilometers. Keratek contains special microceramic particles, as well as additional chemically active components, the task of which is to correct irregularities on the surface of working engine parts. Tests of the additive have shown that the friction coefficient drops by approximately half, which is good news. The consequence of this is an increase in power and a decrease in fuel consumption. In general, it can be argued that the effect of using the German anti-friction additive in Liqui Moly Cera Tec oil is definitely there, although not as “loud” as the manufacturer claims. It is especially good that the effect of use is quite long-lasting.

No visible deficiencies were identified, therefore the anti-friction additive Liqui Moly Ceratec is fully recommended for use. It is packaged in 300 ml cans. Product code - 3721. The price of the specified package is 1900 rubles.

Positioned by the manufacturer as an atomic metal conditioner with revitalizant. This means that the composition is capable of not only reducing friction, but also restoring roughness and unevenness on the working surfaces of individual engine parts. In addition, the Ukrainian anti-friction additive XADO increases (evens out) the engine compression value, reduces fuel consumption, increases power, engine response and its overall resource.

Real tests of the additive have shown that, in principle, the effects declared by the manufacturer are indeed observed, but to an average degree. It rather depends on the general condition of the engine and the oil used. Among the shortcomings, it is also worth noting that the instructions contain a lot of incomprehensible (abstruse) words, which are sometimes difficult to understand. Another drawback is that the effect of using the XADO additive is observed only after a considerable period of time. And the product is very expensive, considering its average effectiveness.

The product is packaged in a 225 ml can. Its article number is XA40212. The price of this canister is 3,400 rubles.

The anti-friction additive Manol Molybdenum (with the addition of molybdenum disulfide) is very popular among domestic car enthusiasts. Also known as Manol 9991 (produced in Lithuania). Its main purpose is to reduce friction and wear of individual engine parts during their operation. Creates a reliable oil film on their surface that does not disappear even under heavy loads. It also increases engine power and reduces fuel consumption. Doesn't clog the oil filter. The additive must be added at every oil change, and at its operating temperature (not completely hot). One package of Mannol anti-friction additive with the addition of molybdenum is sufficient for oil systems with a volume of up to five liters.

Tests of the Manol additive show its average effectiveness. However, the low cost of the product suggests that it is fully recommended for use and will definitely not cause harm to the engine.

Packaged in a 300 ml jar. The article number of the product is 2433. The price of the package is about 230 rubles.

The abbreviation ER stands for Energy Release. ER oil additives are manufactured in the USA. This product is positioned as a metal conditioner or “friction winner”.

The operation of the air conditioner is that its composition increases the number of iron ions in the upper layers of metal surfaces with a significant increase in operating temperature. Due to this, the friction force is reduced and the stability of the mentioned parts is increased by approximately 5...10%. This increases engine power, reduces fuel consumption and exhaust toxicity. Also, the EP conditioner additive reduces the noise level, eliminates the appearance of scuffing on the surface of parts, and also increases the service life of the engine as a whole. Among other things, it facilitates the so-called cold start of the engine.

The ER air conditioner can be used not only in oil systems of internal combustion engines, but also in transmissions (except automatic), differentials (except self-locking), hydraulic boosters, various bearings, hinges and other mechanisms. Good work efficiency is noted. However, it rather depends on the conditions of use of the lubricant, as well as the degree of wear of the parts. Therefore, in “neglected” cases, weak efficiency of its work is noted.

Sold in 473 ml jars. Product code - ER16P002RU. The price of such packaging is about 2000 rubles.

The Russian product Xenum VX300 with microceramics is positioned as a friction modifier additive. It is a fully synthetic additive that can be added not only to motor oils, but also to transmission oils (except for those used in automatic transmissions). Has a long shelf life. The manufacturer notes a mileage of 100 thousand kilometers. However, real reviews indicate that this value is much less. It rather depends on the condition of the engine and the oil used in it. As for protective effects, the composition can reduce fuel consumption and provide good protection to the surfaces of moving engine parts.

One package is enough for an oil system with a volume of 2.5 to 5 liters. If the volume is larger, then it is necessary to add an additive based on proportional calculations. The product has proven itself well when working in various engines, both gasoline and diesel.

Packaged in 300 ml jars. Article number - 3123301. The price of the package is about 950 rubles.

This additive was created using the patented Prolong AFMT technology (manufactured in the Russian Federation). Can be used for a variety of petrol and diesel engines, including turbocharged ones (it can also be used for motorcycles and two-stroke engines, such as lawn mowers and chainsaws). "Prolong ENGINE TREATMENT" can be used with both mineral and. Quite effectively protects engine parts from wear and overheating over a wide range of operating temperatures.

The manufacturer also claims that the product can reduce fuel consumption, increase engine life, reduce exhaust smoke, and reduce oil consumption due to waste. However, real tests conducted by car owners show the low effectiveness of this additive. Therefore, the decision to use it can only be made by the car owner.

Sold in 354 ml bottles. The article number of this package is 11030. The price of the bottle is 3,400 rubles.

Antifriction additives in transmission oil

Less popular are antifriction additives for transmission oil. It is mainly used only for manual transmissions, very rarely for automatic transmissions (due to its design features).

The most well-known additives for transmission oil in manual transmissions:

• Liqui Moly Getriebeoil-Additiv;
• NANOPROTEC M-Gear;
• RESURS Total Transmission 50g RST-200 Zollex;
• Mannol 9903 Getriebeoel-Additiv Manual MoS2.

The most popular compounds for automatic transmissions are:

• Mannol 9902 Getriebeoel-Additiv Automatic;
• Suprotek-AKPP;
• RVS Master Transmission Tr5;
• Liqui Moly ATF Additive.

As a rule, these additives are added along with changing the gearbox oil. This is done to improve the performance of the lubricant, as well as to increase the service life of individual parts. These antifriction additives contain components that, when heated, create a special film that protects moving mechanisms from excessive wear.

You can argue endlessly about whether it is worth or not to use car additives. Visual experiments and tests show that there is practically no point in using additives in the first 5 years of vehicle operation. During this period, the machine and its systems are in excellent condition, everything is perfectly ground together, there are no obvious signs of wear, oxidation, scuffing or other similar phenomena.

After 5 years of operation, the engine begins to show the first signs of obvious wear. They are not so significant and destructive for the internal combustion engine, but if you do nothing and do not carry out any preventive work, the life of the engine will be significantly reduced.

One of the solutions was modern and effective additives. Moreover, it is important to understand that the main characteristic of the best engine additives is their performance, the ability to really help and improve the condition of the power plant. The problem with many additives is the lack of effect. This is just a marketing ploy aimed purely at making money for the manufacturer. But there are also really effective additives, which are included in the current rating of the best additives for oil and fuel systems.

Rating categories

It is difficult to say unequivocally which additive will be better and more effective for a specific engine and a specific situation. It all depends on the problems with the engine, as well as the needs of the motorist himself. Some people are concerned about scuffing, others are interested in the issue of increasing the viscosity of the engine oil. Still others strive to completely reduce the level of exhaust smoke. There really are a lot of options.

• the best restorative additives;
• the best anti-smoke additives;
• the best means to increase engine compression;
• the best additives for diesel internal combustion engines.

This division will allow you to find out which additive added to the oil will be the best for your gasoline engine, or which additive is the best if you have a diesel engine at your disposal. All additives have undergone real tests and have proven their effectiveness in practice.

Restorative additives

First, let's look at the best additives designed to restore the engine. In most cases, such fluids are intended to be added specifically to the engine oil, and not to the fuel tank. Although there are rare exceptions.

Before naming the most effective additives for engine restoration, you need to understand their essence and purpose. Such auto chemicals are aimed at coping with accumulated dirt, carbon deposits and resin deposits that gradually form on the internal surfaces of the internal combustion engine.

Regular and correct use of such products can increase the service life of the engine, increase its service life, delay the need for major repairs, and also reduce engine oil consumption. These are objectively the best additives designed for high mileage engines. But you shouldn’t rely on a bottle of chemical if the engine is in a dying state.

Restoring an internal combustion engine using additives has a number of positive aspects. There is no need to contact a car service, and the cost of the product is small. Just read the instructions carefully and add exactly as much liquid as indicated by the manufacturer. Otherwise, you risk significantly changing the chemical composition of the engine oil, which will ultimately have the opposite effect.

Now let's look at the top of the restoring additives intended for pouring into the engine.

FN710 from Fenom

It is a repair and restoration additive, which is available in a small bottle for one-time use. An organometallic compound is added to engine oil and serves to protect against wear. Restores performance characteristics and can be used for diesel and gasoline power units.

Tests have shown the ability to eliminate microdefects on the friction surfaces of internal moving engine parts. Increases resistance to wear of internal combustion engine elements. Helps the engine better cope with overloads and oil starvation. It also reduces mechanical losses and has a positive effect on fuel and oil consumption. The product can correct compression inside the cylinders.

As the manufacturer himself states, its additive interacts with various contaminants at the molecular level. Helps provide protection against further accumulation of soot and deposits.

CeraTec by Liqui Moly

It’s not often that motorists come across truly effective additives. But there are some. And if we talk about the most effective and useful additives intended for engine restoration, we must definitely mention the CeraTec product produced by a well-known manufacturer, Liqui Moly.

In many ways a universal remedy. It can be used to prevent contamination of internal surfaces on a new engine. The substance also copes well with already accumulated deposits on. Many people recommend adding such an additive during the engine break-in period after a major overhaul.

The restorative properties are due to the presence of microceramic substances in the composition. They fill microcracks in the engine, create a perfectly flat and smooth surface, ensuring optimal movement of the pistons and other moving components of the internal combustion engine. Moreover, the resulting protective layer is characterized by increased strength, which allows you to protect the motor from overloads.

If you don't know which additive is safer and better to put in your engine, given the type of oil you use, choose CeraTec without any worries. This substance is mixed with all types of motor oils. The additive does not form sediment and does not clog filters. Based on the test results, it was found that the effectiveness of the additive can be maintained for 40-50 thousand kilometers.

Off Road Gearbox from Suprotec

In the current rating of additives intended for engines with high mileage and for restoring internal surfaces, it is worth including the domestic development from the company Suprotec. A truly effective and high-quality additive based on a tribotechnical composition.

When it gets into oil, it forms a protective layer with a strong and stable structure on the metal surfaces of the engine. Helps in restoring the geometry and dimensions of parts that have been worn during operation. Helps reduce gaps, allowing oil to remain longer in areas where constant active friction occurs.

Some tests also showed a positive effect on fuel consumption, which decreased by an average of 5-7%. Additionally, it is worth noting a decrease in oil waste, a decrease in vibrations and noise, and smoother engine operation.

Motorists receive a pleasant addition in the form of an easier cold start of the engine after motor inactivity. The product is relevant for those who prefer active driving in fairly aggressive conditions and with increased loads on the power unit.

Anti-fog additives

Anti-smoke is required in order to temporarily reduce the volume of exhaust gas that is actively formed during engine operation, as well as to reduce the amount of noise emanating from the internal combustion engine. But this is a purely preventive and temporary measure, implying mandatory full repairs in the future.

If a car has a problem with heavy exhaust smoke, it needs to be solved not by using additive pressure, but by measuring compression and decarbonization of the engine. Then everything depends on the condition of the engine and what faults were found in it.

Let's look at a few of the best additives that have a wide list of features and benefits, and are also characterized as the most effective anti-smoke additives.

Oil Additive produced by Liqui Moly

It is considered an antifriction additive, which includes molybdenum disulfide. Added directly to engine lubricant. Perfect for cars of previous generations that have an impressive mileage. This additive has been on the market for many years and has long established itself as a very effective and efficient product.

If you are interested in high-quality engine additives that require good cleaning and restoration, then Oil Additiv is almost the most effective among existing additives for gasoline and diesel engines. Auto chemicals are perfectly adapted to work together with synthetic, mineral and semi-synthetic motor oil, do not change its chemical composition, and do not affect the characteristics and lubricating properties.

The development from Liqui Moly does not have a negative impact on engine filter systems and helps reduce engine wear during long runs and increased loads. Helps improve oil and fuel consumption. It copes well with exhaust smoke, although it acts as a temporary measure.

HG2250 from Hi Gear

One of the world leaders in the production of automotive additives. This product is a special complex with universal properties. It has proven itself well as an anti-smoke additive, while simultaneously providing a wide list of advantages and additional capabilities.

Tests have shown the ability of the additive to optimize the performance of rubbing pairs in which increased gaps have formed due to natural wear. It also helps reduce dynamic loads and extends the life of worn motors. The composition includes a special metal conditioner SMT2, which is a new generation development and has proven effectiveness.

Recommended for use on worn diesel and. The additive contains anti-smoke, anti-foam, extreme pressure and reducing components. During tests, it was found that the smokiness and waste of oil with proper use of this additive is reduced by 2-3 times.

Motor Healer from RiMet

If we talk about the highest quality additives from domestic manufacturers intended for engines, then RiMet products are rightly positioned as effective and efficient with a proven positive effect on the internal combustion engine.

Despite its initially different purpose, this composition is considered an excellent option for an anti-smoke additive. The manufacturer himself notes that the additive protects power units from wear, increases their service life and helps delay major repairs.

The composition and properties of Motor Healer make it possible to wash internal surfaces and then create a protective layer on them.

The additive is based on German synthetic oil, which can interact with any type of motor oil. The main feature of the additive is its ability to reduce friction and increase engine power. At the same time, it acts as a restorative and protective agent and reduces engine noise. This is a good preventive measure for new cars whose owners do not want to allow early wear, soot formation and deposits on internal surfaces.

Compression additives

But every motorist must know that it is almost impossible to effectively increase compression without disassembling the power unit itself. An alternative can be special additives, the action of which is aimed at extending the life of the engine. These are synthetic additives that help reduce friction between moving elements, which cannot be achieved with conventional motor oil.

Time-tested and proven automotive additive. It forms high-strength protective films on internal surfaces that literally envelop engine parts. By sealing the gaps, the efficiency of the motor increases, and a certain increase in power is observed. To be more precise, the additive only returns power lost due to wear of the internal combustion engine, and does not miraculously squeeze new horsepower out of the factory engine.

The active component of the additive is a special powder consisting of dust of tin, silver and copper. It penetrates into friction areas and forms cladding layers there. This evens out microdefects and improves the performance of crankshaft bearings and CPGs.

The main useful properties include the following:

• reducing the level of exhaust gas toxicity;
• increased compression;
• reduction of engine oil waste;
• protection against dry friction during overloads, overheating and during a cold start.

It is also important to add that Resurs is one of the few additives on the market that has a so-called surface fatigue relief effect.

Revitalizant EX120 from Xado

Protects motors from wear and prolongs their service life. Suitable for use on gasoline and gas power plants, including turbocharged and forced versions of internal combustion engines.

This is an improved formula that is more effective at restoring worn internal engine surfaces. The main positive properties include:

• protection against consequences during cold engine starts;
• increased compression;
• restoration of worn parts of friction pairs;
• general increase in the resource of the internal combustion engine;
• increase in pressure in the oil system;
• reduction of vibrations and noise;
• optimization of fuel consumption.

In fact, the principle of action of the additive is based on restoring the original geometry of worn parts. Thus, with proper use of the additive, the engine life can be increased by 50-60 thousand kilometers.

Platinum MF444 by Abro

A fairly well-known manufacturer of automotive chemicals and special additives. The product in question is characterized by high efficiency in cleaning the oil system, effectively eliminating carbon deposits, varnish films and carbon deposits. It copes well with coked piston rings and helps create optimal working conditions for them.

Removed contaminants are removed through the oil sump and oil filtration system. The additive makes it possible to eliminate the need to use flushing engine oil.

Diesel additives

There is a separate category of automotive additives that are aimed specifically at use in diesel power plants. A different type of fuel is used here, and the operating mode of the engine is different. Considering the initially low quality of diesel fuel at many domestic gas stations, owners of diesel cars are interested in purchasing truly effective and efficient additives that at least partially compensate for the quality of diesel fuel.

Diesel Zusatz by Liqui Moly

The additive contains a large number of cleaning additives, lubricating components and elements that increase the cetane number.

The additive helps to gently but effectively remove contaminants from the oil and fuel systems, ensures better combustion of the air-fuel mixture, helps increase engine performance and reduce engine oil consumption.

Despite the fact that the composition is intended for the fuel system, the additive has a positive effect on the entire engine, including its lubrication system. Recommended for regular use to get the most out of a proven and proven additive.

Active Plus Diesel by Suprotec

The product is intended for use on diesel cars and small trucks during normal, regular use. It is recommended to pour the composition into cars that have traveled more than 50 thousand kilometers.

With early use of the additive in a diesel engine, it is possible to prevent coking of the piston rings, stabilize and increase compression, and reduce oil consumption. Repeated use restores normal pressure inside the engine's lubrication system, returns the engine to its efficiency, and contributes to a drop in fuel consumption.

Turbo Cleaner by Bardahl

A topical product for diesel turbocharged engines with variable geometry. The additive helps prevent turbocharger sticking problems. Helps eliminate the effect of turbocharging blades jamming without disassembling the unit itself.

The composition includes a large number of active cleaning components necessary to remove carbon deposits and soot. As with Liqui Moly, this liquid is poured into the fuel tank, after which it penetrates directly into the engine itself. It must be added to a full tank, which must be used completely to get the desired effect from using a highly effective additive.

Whether or not to use engine additives is a matter for each motorist personally. There is no denying the fact that a number of supplements on the market actually work. They cannot replace a full-fledged repair or have a miraculous effect on an old, worn-out and almost dead engine.

Experienced motorists and experts advise using additives only as needed. They should not be abused, since in such a situation the effect will be the opposite, and you will only harm your own engine with your own hands. Follow the instructions and do not exceed the recommended dosage. Remember that each additive has its own application features. Therefore, first read the manufacturer’s manual and strictly according to the proposed scheme, fill the liquid into the oil system or the same fuel tank.

It’s even better to carefully monitor the condition of your car, keep the engine in optimal condition by timely replacing consumables, using high-quality lubricating fluids and filling with good, proven fuel. The additive will serve as an auxiliary and preventive measure. It cannot be called superfluous if the additive is used correctly, in a timely manner and for its intended purpose.

A very controversial topic that causes a lot of controversy, both among drivers and among specialists. Despite numerous studies that prove the effectiveness of adding certain additives to the car, not all car owners want to use them. In this article, we will look at which oil additives show themselves to be most effective, and what is the principle of their action.

What are engine oil additives?

Additives are a complex of additives that are poured directly into the engine by the driver, thereby improving the performance properties of the oil used. Additives can extend the life of the motor, but only if they are selected correctly. Depending on different situations, it is advisable to use different compositions.

Please note: Additives are not only used for engine oil. There are separate additives for fuel and gearbox.

Oil additives to reduce engine wear

Liqui Moly Ceratec

One of the most well-known additives added to motor oil is a Liqui Moly formulation called Ceratec.

This additive can reduce the wear rate of parts by up to 30%, reduce friction between parts, reduce (slightly, by about 2-3%) fuel consumption, increase engine efficiency, and minimize the likelihood of engine breakdown when operating in extreme conditions.

Ceratec oil additive is based on liquid ceramics. It contains a lot of elements aimed at “enveloping” the motor elements. Among these components are calcium, magnesium, molybdenum disulfide, boron nitride.

Before using the Ceratec additive, it is necessary to perform and, accordingly,. This composition cannot be used with old motor oil if there is a need to achieve maximum efficiency from it.

Please note: The approximate service life of the Ceratec additive is 50 thousand kilometers. Despite the fact that during this period the oil is changed several times, the additive continues to retain its properties, settling on the engine components.

RVS Master

Another additive that does a good job of reducing engine wear is the RVS Master Engine compound. This brand produces a large number of various additives intended for engines of various classes: motorcycles, cars, trucks, and special equipment.

This additive is based on a compound of magnesium and silicon. They are able to form a film on the surface of engine parts that protects the engine from excessive wear. It is worth noting that this composition also has some restorative functions. It allows you to eliminate small scratches and chips, thereby normalizing compression in the engine cylinders, which leads to a reduction in oil and gasoline consumption and generally improves the quality of engine operation.

The RVS Master additive stands out among its competitors due to its long service life. During operation, it creates a protective layer on the engine elements, which is capable of protecting the engine from the formation of defects for 100-120 thousand kilometers.

3ton Plamet

Another additive for the engine that can increase the service life of the engine. It is based on copper, zinc and boron, which create a protective film on engine parts.

The main task of the 3ton additive is to reduce the friction of engine elements against each other during operation. The additive manufacturer claims that it is possible to reduce engine wear by almost a quarter, thereby delaying the need for major repairs by 25%.

Important: The 3ton Plamet additive must only be added to new oil, otherwise it will lose many of its properties. At the same time, the manufacturer of the composition recommends adding it during the initial stages of engine operation - up to 10 thousand kilometers.

Oil additives for a new engine

If the car has only recently left the factory and has practically no mileage, it makes sense to immediately concern itself with the issue of protecting its engine from possible damage. Most often, engine damage occurs when the filled motor oil in a car has almost reached its expiration date.

To ensure that the oil better retains its properties from the moment it enters the engine until it is replaced, you can use the Hi-Gear HG 2249 additive. Its purpose is to reduce the likelihood of wear on the components of a “young” engine.

This additive consists of organic substances. The complex itself is based on chlorinated paraffin. The formula of the composition allows the filled oil not to lose all its properties by the time it is replaced.

At the same time, this additive reduces the likelihood of oxidation and dilution of the oil. Such a problem with it can occur when it is overloaded and rises to serious temperatures, or when third-party components get into the lubricating fluid.

Please note: The manufacturer of the Hi-Gear HG 2249 oil additive claims that this complex allows, among other things, to reduce fuel consumption by 8%. But independent studies indicate that there is indeed a reduction in fuel consumption, but not by more than 2-3%.

Given the properties of this additive, it is necessary to add it to the oil at every oil change.

Oil additives under high loads

Another type of oil additive is designed for vehicles that are subject to high loads. Also, such additives are called “sports”, since they are supposed to be used by drivers who are involved in motorsports. Such additives include Bardahl Turbo Protect.

This additive is best suited for highly accelerated engines that are turbocharged. The compound used allows the formation of weak ionic bonds between the molecules of phosphorus, zinc and potassium, as well as the area of ​​the metal elements of the engine. Thanks to this composition, this additive works with turbocharged engines throughout the entire service life of the oil, whereas when using other additives, they lose their characteristics in turbocharging after 3-4 thousand kilometers.

Please note: The manufacturer of the additive Bardahl Turbo Protect recommends using 2 bottles of its product at once before the start of competitions where serious overloads in the engine are expected. But such oil will need to be drained after the end of the competition; it is not recommended to operate the engine for a long time with such an amount of such an additive.

It is worth noting the unique technology for the formation of fullerene spheres between rubbing parts, which is implemented in Bardahl Turbo Protect. Such spheres protect engine elements much more effectively than the ceramic or metal coatings and films formed when using other compounds. Fullerene spheres significantly reduce friction and act like small ball bearings.

Important: When using Bardahl Turbo Protect in a car that is not equipped with a turbocharged engine, the effect will be minimal.

Oil additives for cleaning hydraulic compensators

Another important type of composition is an additive that copes with the task of cleaning hydraulic compensators or pushers, thereby allowing the driver not to think about the need to adjust the thermal gap. Such additives include Bardahl Hydraulic Valve Lifters.

This composition consists of a patented complex of substances that eliminate accumulated deposits and minimize the likelihood of sedimentation of soot and other pollutants inside hydraulic compensators. According to studies, the use of such an additive increases the service life of hydraulic compensators and pushers by 2-3 times.

In addition to the function of protecting hydraulic compensators, the additive in question also contains components that prevent wear of other moving engine components by forming a film on them. Using such a solution, it is possible to increase the service life of valves, camshafts and other elements of the intake system. The composition also contains various “washing out” additives that remove negatively affecting deposits.

Important: The composition of Bardahl Hydraulic Valve Lifters is extremely sensitive to the quality of the oil used. It should only be added to new oil that does not contain foreign components.
