5w 30 what kind of oil. Engine oil marking

The car engine needs constant lubrication and protection of components from frictional forces. For normal operation of the power plant, lubricants are needed to protect the motor parts from unnecessary contact. If the technical fluid is selected correctly, then the service life of the unit will noticeably increase. In the market for branded lubricants, motor oil 5w30 takes a leading place in demand among products of synthetic origin.

Any lubricating motor fluid has its own classification and specifications, this must be considered before purchasing the product. Lubricants are used for gasoline and diesel engines. In addition, there are universal formulations that can be combined with any type of power system, including diesel installations. Motor auto-lubricants by their nature are divided into mineral composition, semi-synthetic oil and synthetics.

Today, when choosing a consumable, drivers do not know how the labeling of the engine mixture is deciphered. Let us consider in detail what is the decoding of SAE 5w30, what each of the numbers means, what is the meaning of these values.

Temperature range for engine oils

Special requirements are imposed on motor lubricants. Among the main physical parameters, the viscosity of the substance and its temperature regime are distinguished. In developed countries, the SAE classification is used, taking into account the viscosity-temperature characteristics. 5w30 synthetic oil is marked according to the SAE system. The designation for this classification sets the operating temperature range of the material.

According to SAE, all engine lubricants are classified according to the season of operation:

• Winter mixtures. The low viscosity of the oil provides a guaranteed engine start at low temperatures.
• Summer compositions. Due to its high viscosity, the solution reliably lubricates the vehicle's engine system at high temperatures.
• Universal (all-season) materials. Automotive oils are used both in winter and in summer.

What do the numbers mean? According to this classification, all motor mixtures are divided into 12 groups, including 6 winter categories (0w, 5w, 10w, 15w, 20w, 25w) and 6 summer viscosity groups (10, 20, 30, 40, 50, 60). For multigrade automotive oils, two numbers are indicated in the designation. The first characterizes the properties of the composition in an environment of low temperatures, and the second shows the viscosity of the component in the summer. 5w30 oil decoding:

• The first digit 5 ​​in the product label indicates the minimum temperature regime at which the parameters of the substance do not change. In our case, the lower temperature limit is at least 30 degrees below zero.
• The letter designation "W" indicates that it is advisable to use the lubricant during the cold season. It turns out that SAE 5w engine oil belongs to the winter category of lubricating components.
• The last digit corresponds to the temperature limit at which the lubricant functions normally. SAE 5w 30 engine oil indicates that it only applies up to 30 degrees Celsius.

5w30 oil decoding makes it clear that the mixture can be used at temperatures from -30 to +30 degrees Celsius. To obtain a substance with specified viscosity-temperature properties, a special additive package is required. The additives are capable of thinning the technical solution at low temperatures and thickening at higher values.

Specifications

Engine oil in the engine

Motor oil 5w30 has a lot of advantages. The excellent performance of this component helps you cope with harsh operating environments. An adverse effect on engine parts is considered:

• long-term operation of the vehicle at idle speed;
• constant stops and traffic jams;
• increased gas pollution and dustiness of the area.

Thanks to the synthesis reaction of a set of additives and a universal structure, motor oil 5w30:

• protects the mechanisms and elements of the engine from mechanical and chemical effects;
• forms a stable oil film on parts;
• slows down oxidative and corrosive processes;
• relieves working surfaces from carbon deposits and other deposits;
• cools the components of the system properly.

Motor oil 5w30 impresses with its characteristics. When choosing a lubricant for the power unit of a car, you need to pay special attention to its technical documentation. These acts contain the manufacturer's recommendations for engine operation. The same document establishes the tolerances for automobile oils, but it must be remembered that the manufacturer's recommendations are aimed only at the "heart" of the car.

Chemical base

7TOTAL Quartz INEO 5W30

The complex of additives included in the SAE 30 greases perform strictly specified functions in specific types of propulsion systems. The additives used meet all regulations and regulatory standards. Choosing a consumable for your car is an individual decision for the driver. He takes into account some of its technical characteristics and chooses a lubricant according to his taste and natural origin. It is widely believed that 5w30 mineral oil in used machines results in lower consumable consumption and longer motor life. Synthetics or semi-synthetics are used for more modern cars, but it all depends on the owner. If the owner has a power plant that has not yet been run in, then it is recommended to use synthetic compounds. The synthetic motor lubricant SAE 5w30 is also in this category.

It is worth noting that before obtaining a quality certificate, a test of 5w30 oils and their chemical analysis are performed. As a result of tests of SAE 5w30 engine oils, it is possible to accurately simulate real operating conditions and record the results obtained. The product packaging contains all the necessary information about the conformity of the properties of the lubricant mixture to the declared requirements. Tests of synthetic motor oils reveal to customers the technical parameters of the purchased mixtures from different manufacturers. No one is insured from buying a low-quality product, which means it is easy to fall for the bait of an unscrupulous seller, so you should not buy car oils at unverified points. It is more rational to visit official points of sale, where the possibility of purchasing fake engine oil is reduced to zero. Before buying a product, you should carefully examine the packaging for scuffs and scratches, deformation of the cover and information label. Consider the description of some popular auto mixtures, where the best ratio in terms of engine oil quality and price:

• ZIC XQ 5w-30. Lubrication - all-season and is intended for a turbocharged engine (turbocharged units) or without it. The oil combines two main functions - the reliability of the engine and economical fuel consumption.
• General Motors Dexos2 Longlife 5W30. A feature of this substance is considered to be the high lubricity of the parts of the power unit, which makes it possible to operate the car in difficult conditions.
• TOTAL Quartz INEO 5W30. The mixture is distinguished by its sulfate low ash content. Thanks to this characteristic, fuel is saved and the emission of harmful substances is reduced. The component is intended for both gasoline systems and diesel

Let's summarize

Synthetics SAE 5w 30 is a demi-season lubricant mixture. Due to this property, 5w30 motor oil is applicable all year round, even in conditions of unexpected temperature changes in the off-season, while maintaining all its "useful" functional characteristics in any type of engine.

Engine oils are oils that are used to lubricate pistons and rotors in an internal combustion engine. Today they are a base fluid with additives that increase the parameters. Distillates and residual elements with different viscosity index (hydrocarbon components), their mixtures, synthetic substances (ethers, olefins) are taken as a basis. The main part of all-season lubricants is produced by thickening a low-viscosity base with macropolymers.

What is required from car oils

Automotive lubricant is a significant part of the internal combustion engine. It is able to perform its own task for a long time and reliably, to provide a certain engine resource only if its indicators are fully consistent with those temperature, chemical and mechanical influences that it transfers in the lubrication complex of a car. Description of the basic requirements for motor oils:

• Good detergent properties in relation to various contaminants, which ensures the cleanliness of the motor elements;
• Wear resistance, which is achieved by a durable oil film and optimal viscosity;
• Lack of corrosive effects on internal combustion engine components;
• Resistance to aging, the ability to cope with external influences, minimally deteriorating their performance;
• Compatibility with seals and catalysts;
• Low foaming properties;
• Low volatility, low waste consumption.

Certain lubricants have special requirements. For example, lubricants that are thickened with additive macropolymers must have the necessary stability to thermal destruction. For energy-saving lubricants, antifriction properties and good rheological characteristics are important.

How oils are classified by origin

V Depending on the chemical composition, as well as the method of making the base, lubricants are divided into a couple of broad subgroups - mineral and synthetic. Mineral oily liquid is made from petroleum by distillation. Synthetic is produced by means of organic synthesis, also on a petroleum basis, but with a more complete processing of the base substance.

There are also semi-synthetic lubricants. Semi-synthetics are made by adding synthetic elements to mineral oil. Semi-synthetics is not quite the correct name, it would be more correct to say “mineral with added synthetic elements”.

Decryption 5w30

Often, when purchasing engine oils, car owners do not understand what the decoding of 5w30 is. What does this oil data show? For which cars is it desirable to use it? In order to fully decipher the marking of the oil liquid, a special base has been created.

The lubricant is divided according to the scope of its use, respectively, with the API (Petroleum Institute). On the back side of the canister, the API designation does not indicate quality, but performance characteristics. For example, the letters S or C indicate that the lubricant should be used in a gasoline / gas engine. That is, if semisynthetics or synthetics A3 / B3 category resembles API SL / CF in properties, then its use exclusively in turbocharged engines is irrational.

For such power units, a semi-synthetic oil with a low viscosity and excellent environmental characteristics is optimal. In view of this, a grease such as ACEA A5 / B5 is now common among many engine manufacturers. This oil can outperform API SM / CI-4 in many indicators. It is no secret that with the correct choice of an oil fluid of the ACEA category, the likelihood of the need for a complete repair of the power unit decreases.

There is also an ISLAC engine oil. It indicates that the product has been manufactured in accordance with the requirements of the American Japan Committee. Hence, a lot of data is the same as the API. For example, ISLAC GL-2 is almost the same as API SL in terms of its performance.

What if you need to buy energy-saving grease for your car? Such oil makes it possible to significantly reduce fuel costs. According to the parameters of “High temperature / high shear viscosity, this oil is suitable for high temperature operation. In other words, if the temperature of the motor becomes more than one hundred degrees Celsius, the following increases:

• Oil viscosity index;
• Oil film thickness;
• Fuel costs.

When using an energy-saving lubricant, the viscosity under similar operating conditions is less than that of regular oil, but the oil film is thinner. In addition, the owner of the car should be aware of the possibilities of using the grease at different temperatures.

5w30 value

The Russian Federation is a large state, in some parts of which there is severe cold, in others - unbearable heat. In view of this, any car owner should know the technical characteristics of a car oil.

5w30 oil is marked according to the special SAE system. By marking it is possible to establish the temperature at which it is necessary to use it. Accordingly, with SAE 5w 30 it is intended for use in winter, but it can also be used in summer. The decoding of 5w30 engine oil is as follows:

• The first number tells you what the lower temperature limit is at which the properties of the oil (say, viscosity) do not change. "5" means that this grease can be filled in if the air temperature is not lower than minus thirty degrees. It also shows how smoothly and at what speed the lubricant will pass through the oil complex to the working surfaces, how much energy will be spent in this case;
• The letter indicates at what time of the year it is recommended to use the lubricant. "W" - preferably for use in winter conditions;
• The last number shows the maximum temperature at which it is possible to use oil normally (if the temperature of the power unit is not more than one hundred degrees). "30" means that the oil can only be used at temperatures up to plus twenty-five degrees.

The main criterion when choosing an engine oil is the recommendations of the engine manufacturer. For markings of the 5w30 type, decoding the parameter values ​​will help determine the most suitable engine oil option for specific operating conditions. You have to choose from a number of designations allowed by the manufacturer for each engine.

Viscosity indices

The specialists from the Society of Automotive Engineers, or SAE for short, suggested marking the characteristics of lubricants with a combination of letters and numbers, such as 5w50, 10w 40. The separator between digital indices in the form of the Latin letter "w" refers to the first of them and comes from the English word winter (winter). The numbers are the viscosity indices. These values ​​are based on SAE J300 APR97.

The first index indicates the starting properties of the oil in conditions of boundary temperature drops. It can take values ​​from 0 to 25 in increments of 5 units. Oils 20w and 25w are not relevant for domestic conditions. Each low-temperature viscosity index corresponds to the standard temperature values ​​for which oil can be pumped through the system and the engine crankshaft cranked by the starter.

The second indicator depends on the viscosity of the oil at the engine operating temperature.

It can take values ​​from 20 to 60 with an interval of 10 units. Each of them has a viscosity range at 100 ° C. For these values, the viscosity at 150 ° C and the shear rate of 10 6 s −1 are also normalized.

The dependence of oil properties on temperature conditions according to the SAE classification is presented in the form of a table:

It can be seen from the standard that 5w30 oils must ensure a stable start of a working engine with a fully charged battery when the temperature drops to -30 ° C after a long stay. For the second parameter 30, the decoding gives that on a warm engine in the zone where the oil temperature is about 100 ° C, its viscosity should be in the range of 9.3.12.6 mm² / s. Similarly, you can determine the parameters that must correspond to oils 5w50, 10w 40 and others.

Criterias of choice

With the 1st parameter, everything is simple. The lower it is, the better. Cost becomes the limiting factor. Oil 0w, other things being equal, turns out to be more expensive than 5w and even more so 10w. For regions with a temperate climate, the overpayment for the stock in terms of starting properties does not seem justified.

The 0w and 5w values ​​are typical for the highest quality synthetic oils. With indexes 5w and 10w, semi-synthetic oils, optimal in terms of combination of price and quality, are produced. Budget mineral oils are available in low temperature viscosities of 10w and 15w.

The second parameter is more complicated. There is no overall optimum high temperature viscosity for any engine. The designers coordinate the dimensions of the gaps, the types of surface treatment, the cross-section of the oil channels, the pump performance, the temperature modes of operation with the oil viscosity required for a given combination of conditions.

Until recently, the most popular type of oil in our country was semi-synthetic, with a viscosity of 10w 40. It was perfect for domestic front-wheel drive cars and budget foreign cars with outdated engines. Large enough clearances, the absence of turbines and variable valve timing systems made it possible.

Motorists, who prefer to drive aggressively, tended to flood "sports", as it was presented by marketers, 5w50 or 10w60 brands. For conventional engines, this led to a change in the thickness of the lubricating film, an increase in hydraulic losses, a decrease in efficiency and an increase in operating temperatures with a correction for a resource.

In recent years, carmakers have prioritized fuel economy. As a result, the priorities began to shift towards a more liquid oil in operating modes 5w30 or 0w30. Reducing clearances and increasing fluidity have a positive effect on engine output and fuel consumption.

For the most modern Japanese and Korean engines, manufacturers indicate oils with a viscosity of 5w20 and 0w20 as the main ones. Such products provide excellent performance indicators, but due to their operation with a minimum oil film thickness, they require the highest quality parameters. Economical liquid oils are comparatively expensive. The resource is depleted faster, so replacement should be done more often. European designers still prefer 30s.

Transmission standard

There is an SAE specification for transmission lubricants. Analogies with engine products are irrelevant in this case. Decoding 10w 40, 5w30 or any other engine oil to determine starting properties is very simple. It is enough to subtract the number 30 from the low-temperature index. This will be the approximate temperature in ° C at which a stable engine start is possible.

The 75w90 marking for the "transmission" does not mean that it loses fluidity even at a positive temperature. The flow temperature parameters of these products are described in SAE J306. The low-temperature and high-temperature index values ​​for transmission products are chosen so that they do not overlap with the series of values ​​for the engine grades. The values ​​are 70W, 75W, 80W, 85W for the "winter" series and 80, 85, 90, 140, 250 - for the "summer".

The value of the maximum permissible viscosity at low temperatures was taken to be 150,000 cP. With a greater decrease in fluidity, there is a likelihood of destruction of bearings and other elements of gearboxes and drive axles. The upper yield point should provide sufficient oil film thickness at 100 ° C, based on the potential point loads in the particular assembly.

So, for a product marked 75w90, the permissible operating temperature is -40 ° C, and the viscosity when heated to 100 ° C should be in the range of 13.5.24 mm² / s. The 75w90 marking is typical for synthetic products that are poured into gearboxes of modern passenger cars.

Every driver should at least roughly know the classification that engine oils have in order to easily determine which lubricant to buy at one time or another. Most often, car owners use all-season mixtures, since it is very convenient and practical. In Russia, one of the most common oil is SAE 5W30. It can be used both in frost (from -35 ° to -25 ° C) and in warm weather (25-30 ° C). Like all other lubricants, this fluid can be mineral, semi-synthetic, or synthetic. The first of the options has not been produced for a long time, but the other two are very popular. But how do they differ, and which one is better?

Synthetic oils

Synthetics are the best type of engine oil. However, this is not only due to cost. Thanks to the production technology and composition, the lubricating fluid ensures stable vehicle start-up in any weather, effective protection and economical fuel consumption. The oil is created entirely from artificial components (as opposed to semi-synthetics, which also includes natural elements). This allows the lubricant to be resistant to ignition and combustion, which makes evaporation much slower.

The undoubted advantage of the oil is its extended temperature range. Synthetics 5W30 will allow you to start the engine in the most adverse weather conditions.

For example, the average minimum temperature of liquids in this category is -30 ° C, however, synthetic Liqui Moly lubricants with a viscosity of 5W30 are able to start the car even at -35 ° C. The upper heat point also depends on the manufacturer, while its value usually does not exceed 25 ° C. Otherwise, the oils must be labeled with a viscosity grade of 5W40.

The advantages of synthetic formulations also include a reliable oil film that forms as a result of filling the lubrication system. This important component helps to protect the friction parts of the engine from wear. For the same reason, with synthetics, the power unit of the car makes a little less noise, since the slip improves.

The main disadvantage of synthetics is its price. Good oil A 5W30 generated entirely from artificial components will cost about 2 times more than semi-synthetics. In addition, a greater amount of carbon deposits should be attributed to the disadvantages, however, this is compensated by the presence of active detergent additives in most lubricants, which remove combustion product residues well.

Each manufacturer uses its own technology for the production of engines, so the same oil may not be suitable for different units. Some concerns produce their own 5W30 synthetic lubricants, for example, Ford, Volkswagen, Nissan. There are other multi-grade greases in this class that can suit most machines. The best are Castrol Magnatec A1 5W30, Petro-Canada Supreme Synthetic 5W30 and Shell Helix Ultra Extra 5W30.

Semi-synthetic oils

High-quality synthetics are sometimes not available in affordable stores, or there may not be enough money for it. In such cases, it would be preferable to buy a reliable 5W30 semi-synthetics. Such mixtures are created from artificial and natural ingredients. Those oils that are more expensive contain a higher percentage of synthetics (up to 70%). If the price of a consumable is low, then, most likely, mineral elements in it can occupy up to 50%.

Semi-synthetic oil is not at all synonymous with poor quality. The demand for such mixtures is relatively high, so manufacturers strive to make them no worse than synthetic ones. A major advantage of this category of lubricants is their improved cleaning properties. Semi-synthetics protect the friction parts of the unit much better than completely artificial counterparts, due to which it is not clogged with residues of combustion products.

The protective properties of 5W30 mixtures are no worse. All moving elements of the engine work stably and without unnecessary noise, which changes the sound background of the internal combustion engine for the better. Of course, wear does not slow down so much, nevertheless, reliable protection of parts is provided (of course, if the mixture itself is of high quality). In addition, good semisynthetics should slowly evaporate due to a thicker composition, and this is also a big plus.

The main disadvantage of engine oils with mineral components is the shorter drain intervals.

It is best to top up the mixture at regular intervals, otherwise an empty lubrication system can take the driver by surprise. In addition, some natural elements are not as mobile and elastic as artificial ones, so the oil film can sometimes be damaged (you can fix it by adding liquid).

What choice to make?

So synthetics or semi-synthetics? The answer to this question lies in two things: the make of the car and the wallet of the car owner. The first factor concerns those vehicles in which it is best (and sometimes necessary) to use synthetics. This applies to cars with high-performance multivalve power units, including turbocharged ones, which can deliver the required power and torque only with the right oil in the system.

In addition, the driver's finances also play an important role. If there is no money for a high-quality synthetic fluid, then it is better to take a good semi-synthetics. If the car owner can afford more expensive materials, it is better to purchase reliable synthetics.

Conclusion

Engine oil plays a critical role in engine performance. Without it, the car will neither start nor drive. Therefore, it is imperative to use reliable lubricants to keep the vehicle running smoothly.

The most popular of all the presented fuels and lubricants is the 5w30 synthetic motor oil from the world's leading brands.

The main and main task of lubricants is to protect engine parts from dry running and to ensure its normal operation in conditions of complete tightness of working cylinders. Correctly selected engine oil is a guarantee of the correct operation of the engine and increases the service life of its components.

The market for fuels and lubricants is represented by three product categories:

• for cars with gasoline engines;
• for diesel units;
• universal, which have physical characteristics that allow them to be used in engines internal combustion and diesel engines.

According to the seasonality of use, lubricants are distinguished:

• winter - 5w, 10w
• summer,
• all season - 0w 30, 5w30

Regardless of the category of lubricant product, engine oil has a major parameter of physical properties that determine its effectiveness. This is viscosity (5w30), that is, the ability lubricant maintain fluidity while remaining on the surface of the parts. The protection of parts from friction and wear during vehicle operation depends on this indicator. If the viscosity (5w) does not correspond to the recommended one, then the engine life will be reduced. The second indicator (30) is also of great importance - this is the high-temperature viscosity. Its deviations from the recommended one can lead the engine to overhaul faster than it was originally planned. Since in this case the motor operates at increased speeds, which can bring it out of the range of maximum permissible norms.

When choosing a lubricant, you need to take into account the viscosity index. It should not exceed the parameters recommended by the manufacturer. Otherwise, you will increase the load on the engine, which can lead to serious damage and subsequent costly repairs.

How to make the right choice?

What should you look for when choosing universal fuels and lubricants for your car?

1. Viscosity index.

• It is on him that the ability to start the engine in winter conditions depends. The lower this indicator, the easier the engine obeys the ignition signal.
• The degree of coverage of engine parts with a lubricant depends on viscosity in order to prevent friction and wear, as well as to prevent chemical and mechanical damage.

1. Temperature conditions.

• It defines the minimum threshold for the effectiveness of a given type of lubricant in the cold season.
• It also sets the temperature range at which the use of an oil liquid guarantees safe operation of the vehicle when the engine is heated.

This classification of fuels and lubricants in terms of viscosity and temperature conditions was established by the American community of engineers SAE. Conformity of engine oils to this classification is indicated on each “sae” package.

5w 30 series

The most popular of all the presented fuels and lubricants is synthetic motor oil of the 5w30 series. The characteristics of the products of this group meet the stringent requirements for operating vehicles in urban conditions and on highways. The city mode is different:

• long idle operation of the motor,
• idle car in traffic jams,
• stable trips over short distances,
• increased dust content in the air.

These factors significantly reduce the service life of the motors. Correctly selected oil product is the key to long-term operation and technical good condition of the engine.

Automotive lubricants of the sae 5w30 class are distinguished by a unique formula based on the synthesis of an oil base and a package of additives, which are characteristic of synthetics, providing:

• protection of the engine from friction and wear of parts,
• resistance to oxidative processes during operation in conditions of high humidity and climatic precipitation.

The additive package can be different. All of them perform only their specific functions. It is the balanced set of additives that makes the oil base suitable for use in any particular type of engine. In each specific type of lubricant, the compliance of the additives must be within the framework of the standards for the quality of engine oils.

It should be noted that changes in the heating temperature of the motor can change the properties of the lubricating components. Depending on the intensity of its operation, engine oils of the sae 5w30 class can heat up to 150 ° C. When choosing an engine oil, you must rely on the specifications recommended by the car manufacturer. Oil tolerance is not given for a specific car brand, but directly by the type of engine. Therefore, the brand of oil fluids can be any, but the main parameters of the lubricant must meet the requirements set by the manufacturer of your car.

Buying synthetic or mineral motor oil with a sae 5w30 rating is a purely personal matter. It depends on the age of the machine, the characteristics of the engine and the characteristics of the operating conditions. Some are inclined to believe that cars older than 5 - 7 years old better perceive mineral lubricants, as this allows you to reduce the consumption of oil liquid and increase the service life of the engine. In this case, it is better to opt for higher viscosity.

For cars with engines of a new generation and foreign production, synthetic motor fluids are recommended for use. Of this series, synthetic motor oils of the sae 5w30 class are in the greatest demand, since they meet the climatic conditions and traffic intensity in the urban format.

Changing the lubricant

The frequency of changing the lubricant in a car depends on the operating conditions, mileage, condition of engine parts. The best option is 10 thousand km. In difficult conditions of use, this period can be reduced to 7 - 8 thousand km. mileage. With a dual fuel format, for example, "gasoline - gas", the replacement period is increased to 15 - 20 thousand km. This is due to the fact that gas fuel is a more environmentally friendly product and has a softer effect on the parts of the unit. The quality of the engine oil in the engine and its quantity should be checked every two weeks. For this, cars have a special dipstick indicating the minimum and maximum oil level.

Classification and standards

Motor oils of the sae 5w30 class synthetics meet the requirements of environmental friendliness. All representatives of this group not only have compliance with SAE, ACEA and API, but are also certified for use in vehicles with valve gasoline and diesel engines from such major manufacturers as: BMW, VOLVO, RENAULT, MAN. To obtain the manufacturer's approval, all oil products undergo strict control and numerous tests. All declared characteristics must meet the requirements of the manufacturers.

SAE - classification of lubricant products by viscosity (5w);

ACEA is a European classification based on the set of additives and the quality of the final product.

API - American classification of fuels and lubricants by engine type. Separates the purpose of the oil for use in gasoline (SJ) and diesel (CF) engines. The absence of this information indicates an outdated quality class.

Benefits of choosing 5w30 synthetics

Due to its technical composition, synthetic 5w30 has the following advantages:

• enhanced protection of the internal parts of the motor from mechanical and chemical influences;
• provide a super-strong film coating of engine parts from the inside;
• protective properties against oxidation and corrosion;
• protective functions in relation to the moving parts of the motor from mechanical friction and wear during operation;
• a longer range of time between engine oil change procedures;
• universal lubricant composition 5w30 allows the use of fluids of this class in different types of power units.

Synthetics sae 5w 30 is a demi-season lubricant that allows it to be used all year round. There is no need to change oil in accordance with seasonal changes. At the same time, it does not lose its properties and remains effective for any engine.

Synthetics 5w 30 CF series for diesel engines

Synthetic low ash motor oil 5w 30 is designed for diesel cars and is equipped with a double exhaust gas cleaning system. This category complies with national environmental standards for lubricating fluids. Recommended for vehicles with particulate filters, turbochargers and catalysts. Compliant with the latest API SN / CF, ACEA C3.

In the production of 5w 30 diesel engine oils, modern basic components are used, developed according to new nanotechnologies. They increase protective functions and reduce waste emissions. Synthetic additives have a reduced content of sulfur, phosphorus and chlorine bonds.

5w30 engine oils have the characteristics recommended for filling in diesel engines With particulate filters and turbines:

• keep the working unit clean;
• provide quick access to motor parts;
• maintain normal operating pressure in the engine at any degree of load;
• guarantee strong lubrication at low and high temperatures;
• reduce fuel consumption;
• reduce the amount of exhaust gases.

The sae 5w 30 diesel engine oils guarantee high vehicle performance and increase the service life of gas converters. Automakers allow the use of sae 5w 30 synthetics with the specified properties, which preserves preferential conditions for car maintenance during the warranty period.

Modern lubricants have the ability to reduce fuel consumption. As a universal lubricant, engine oils are used in both new generation cars and old models of world car manufacturers. One of the most significant indicators in the choice of a lubricant is its compliance with all necessary regulations and standards.
