What kind of oil to fill in a pneumatic wrench

Recommendations for the selection and operation of oil

• The quality of the oil should not be suspicious. It is best to pour oil from well-known manufacturers into the car, at authorized stations where you will definitely not be poured with a fake (unfortunately, oil is faked quite often).
• For the region in which you operate your car at temperatures in the winter period not lower than 10-15 degrees Celsius, there is no urgent need to use synthetic engine oil, unless, of course, all other oil parameters are suitable for your engine. But still, for reassurance, I recommend pouring 5w-40 synthetics in winter, and 10w-40 semisynthetics in summer. You just have to change a semi-synthetic oil a little more often than you would change a synthetic one. To whom the opportunity allows, it is better to constantly pour one synthetics, so as not to adapt to the season.
• Warm up the engine. In the oil that is not heated to the operating temperature, the additives do not have time to neutralize the acids formed from the products of incomplete combustion of the enriched fuel-air mixture, which intensifies the corrosion processes in the cylinders. Under load (when driving or when the air conditioner is on), the engine warms up faster, so in cold weather it should take no more than 2-3 minutes to warm up “in place”.
• Changing the brand of car oil is not very useful for the engine (let’s be honest – harmful).
• When choosing an oil viscosity (from the approved ones), the following rule must be followed: the more mileage / older the engine, the increased oil consumption – the higher the high-temperature viscosity of the oil should be (within the range approved by the automaker). It is also possible to switch from synthetic to semi-synthetic oil.
• It is forbidden to mix oils from different manufacturers! It is bad, first of all, because completely different additives are mixed, which are contained in these auto oils, and it is completely unknown what the chemical reaction will be with such mixing. It is absolutely clear that the resulting mixture cannot meet any standards or requirements. Therefore, you need to understand that any mixing of different oils. this is an extreme measure. Based on the above, it is possible that if it is necessary to add oil, it will be less harmful to add oil from the same manufacturer (of a different type, viscosity, etc.) than the same in terms of parameters, but of a different brand.
• When changing the oil, it is necessary to flush the engine with flushing oil in the following cases: on diesel engines (flushing oil washes away all the soot), on gasoline engines in the case of heavily dirty oil, and on all engines in case of changing the oil grade. Timely flushing of a running engine will help eliminate jamming of hydraulic lifters, sticking of piston rings, coking of oil channels, and also ensures equalization of compression in different cylinders. Attention! We do not recommend using five-minute flushes, especially on diesel engines (vapors of a highly evaporating solvent enter the crankcase ventilation, then into the suction manifold, from which the diesel will run wild).

ACEA engine oil classification

Classification of motor oils ACEA (Association des Constructeurs Europeens de L’Automobile) – the European analogue of the American API classification.

ACEA motor oils are divided into three categories:

• A / B. motor oils for gasoline and diesel engines. This category includes all previously developed classes A and B (until 2004, A – motor oils for gasoline engines, B – for diesel engines). Today there are four classes in this category: A1 / B1-04, A3 / B3-04, A3 / B4-04, A5 / B5-04.

• C is a new class. motor oils for diesel and gasoline engines that meet the latest toughened Euro-4 emission standards (as amended in 2005). These engine oils are compatible with catalysts and particulate filters. Actually, it was the innovations in the European environmental requirements that became the reason for the reconstruction of the ACEA classification. Today there are three classes in this new category: C1-04, C2-04, C3-04.

• E – motor oils for heavy duty diesel engines. This category has existed since the introduction of the classification (since 1995). In 2004, cosmetic changes were made, 2 new classes E6 and E7 were added, and two other, obsolete classes were excluded.

What kind of oil to fill in the engine?

Many motorists save on oil, preferring the cheaper one to the expensive one. Others, on the other hand, buy the most expensive oil on the market and pour it into their car. But the funny thing is that neither one nor the other is absolutely wrong. The engine resource depends on the oil by almost 50%.

Without going deep into the details, engine oil is a mixture of an oil base and additives. The base is obtained either from oil (mineral motor oils), or by chemical synthesis (synthetic motor oils), or by mixing mineral and synthetic bases in different proportions (semi-synthetic motor oils). The base itself has a basic set of lubricating and operational properties, but its use in an engine is impossible without the addition of various additives, allowing to take into account different modes and service life of the engine..

Additives are substances that are added to engine oil in order to strengthen, weaken, stabilize certain existing properties and characteristics of the engine oil, or to acquire new oil necessary for normal engine operation..

What types and groups are motor oils divided into?

Depending on the different properties, motor oils are divided into groups according to certain parameters:

• According to the chemical composition of the base (mineral, semi-synthetic) synthetic oil.
• Viscosity grade (SAE classification).
• By the set of additives and quality (API and ACEA classification)
• According to the approvals of car manufacturers (oil tolerances).

The main criterion for distinguishing motor oils is viscosity

The viscosity of the oil most of all changes depending on the temperature, being a “variable” value, the most important characteristic and is selected depending on the design of the engine, its operating modes and many other factors.
Currently, the only recognized system for the classification of automotive engine oils by viscosity in all countries is the SAE J300 specification. SAE is an abbreviation of the Society of Automotive Engineers, which describes the viscosity of a particular motor oil at different operating temperatures. In fact, this classification gives the temperature range in which the engine is safe to operate, provided that the engine manufacturer has approved an engine oil with such parameters for use in this engine..

The oil viscosity for this system is expressed in conventional units. grades of viscosity SAE (SAE Viscosity Grade – SAE VG). So what do the oil viscosity numbers on the label mean??

After the SAE abbreviation, we see several numbers separated by the letter W and a hyphen, for example, 5W-40 (for multigrade oil, which, as a rule, all motorists use). We decipher this inscription: 5W is a low-temperature viscosity, which means that a cold start of the engine is possible at a temperature not lower than -35 ° C (that is, 40 must be subtracted from the number in front of W). This is the minimum temperature of the car oil at which the engine oil pump can pump oil through the system, while preventing dry friction of internal parts. This parameter does not affect the operation of a warmed-up engine..
If we subtract 35 from the same figure (in this case, it is 30 ° С), then we get the minimum temperature of the engine “cranking”. Obviously, as the temperature drops, the oil becomes thicker, and it becomes more difficult for the starter to crank the engine during a cold start. But this is an average parameter, the real picture very much depends on the engine itself.
So, if you live in a region where the air temperature in winter rarely drops below 20 ° C, almost any oil on the market will suit you. Another question is in what condition your starter, battery and compression are: if they are already a little tired, it will certainly be easier for them to start the engine at 20 ° C with 0W-30 oil than with 15W-40.

The second number in the designation is the high-temperature viscosity (in this case, it is 40). It cannot be translated as simply as the first into a language understandable to a motorist, because it is a collective indicator indicating the minimum and maximum viscosity of the oil at operating temperatures of 100-150 ° C. The higher the number, the higher the viscosity of the engine oil at high temperatures..

Below are the standard ranks of the classification:

winter row: SAE 0W, 5W, 10W, 15W, 20W, 25W (W – winter);
summer range: SAE 20, 30, 40, 50, 60.

The viscosity of the car oil must meet the requirements of the car manufacturer, regardless of age, mileage, driving style, budget and “authoritative” opinion of servicemen, even if it is an official service.

If the viscosity of the oil is higher than the norm stipulated by the manufacturer, the engine constantly operates in the mode of increased friction and elevated temperatures, from which its parts wear out faster and fuel consumption increases. In addition, operating temperatures also directly affect the resource of the engine oil itself: the higher the temperature, the sooner the oil oxidizes and becomes unusable. So, this oil needs to be changed much more often..

If the viscosity of the oil is below normal, then at high temperatures and at high speeds the film created on the friction pairs becomes too thin, as a result of which the lubrication efficiency decreases and the oil consumption for waste increases significantly. Under certain circumstances, the motor can even jam.

The chemical composition of the base oil

The chemical composition of the base of the oil is a substance obtained as a result of synthesis.

The main operational difference between synthetic motor oil and mineral and semi-synthetic motor oil is:

• Higher viscosity index (less viscosity change with temperature).
• Better fluidity at low temperatures.
• Higher aging resistance.
• Less volatility.
• Higher stability at high temperatures.
• Best anti-friction properties.
• Less “thickening”, ie the amount of additives required to obtain similar properties.
• Increased resistance to shear deformations.

And as a result, there are a number of excellent arguments for using synthetic motor oils:

• no problems during cold start of the engine (based on points 1 and 2);
• faster oil flow to engine parts after a cold start, therefore – less wear of parts during cold start (based on points 1, 2 and 6);
• significant fuel savings, especially with frequent cold starts and short runs (based on points 1, 2 and 6);
• low oil consumption (based on point 4);
• more reliable protection against high-temperature deposits (based on points 3 and 5);
• higher stability of characteristics, allowing, with the approval of the car manufacturer, to increase the intervals between oil changes (based on point 7);
• higher lubricity at high temperatures (based on points 1, 5 and 6).

There is perhaps one drawback of synthetic oils – high cost.

Mineral motor oil is a natural raw material obtained from petroleum. We do not consider pure mineral oil, since it is not suitable for any of the modern engines..

Semi-synthetic motor oil is made from a mixed base, where 30-50% is a synthetic component, and, accordingly, 50-70% is mineral. Such oil really has much better stability characteristics than mineral oil, but inferior to synthetic oil. Semi-synthetic engine oil is recommended to be poured into modern engines with high mileage when the waste of synthetic oil increases.

API classification of engine oils

This engine oil classification system was created in 1969 by the American Petroleum Institute. Popularly, the API classification is also called the classification by the quality of engine oils..

In particular, this classification divides motor oils into two types: for gasoline “S” and for diesel “C” engines. For each of these types, quality classes are provided, which, in fact, describe a certain set of properties and qualities for motor oils of each class..
On the label, information on the assignment of an API class to an engine oil is provided in the following form: API SJ, API CF-4 or API SJ / CF-4. If the engine oil can be used in both types of engines, then this oil is assigned two classes – for diesel and for gasoline engines. On the oil label, these classes are separated by a forward slash (forward slash) – for example, API SJ / CF-4. At the same time, the first is the class of oil that corresponds to the more preferable (according to the manufacturer of the car oil) application.. That is, in the above case, the main purpose of the car oil is for gasoline engines, but at the same time, the manufacturer allows its use in diesel engines.

API engine oil quality classes: gasoline engines

API class SM. Class approved on November 30, 2004.

Motor oils for modern gasoline (multivalve, turbocharged) engines. Compared to the SL class, engine oils that meet API SM requirements must have a higher level of protection against oxidation and premature wear of engine parts. In addition, standards have been raised regarding oil properties at low temperatures. Engine oils of this class can be certified according to the ILSAC energy efficiency class.

Engine oils that meet the requirements of API SL, SM can be used in cases where the car manufacturer recommends class SJ or earlier.

API SL class – Motor oils for engines of cars manufactured after 2000.
In accordance with the requirements of car manufacturers, motor oils of this class are used in multivalve, turbocharged engines running on lean fuel mixtures that meet modern increased environmental requirements, as well as energy saving.

Automotive oils that meet API SL requirements can be used in cases where the car manufacturer recommends the SJ class or earlier.

SJ API class. Motor oils for use in gasoline engines since 1996.

API SJ class describes motor oils that are used in gasoline engines since 1996. Motor oils of this class are intended for use in gasoline engines of cars and sports cars, vans and light trucks, which are serviced in accordance with the requirements of car manufacturers. SJ provides the same minimum standards as SH, plus additional carbon and low temperature requirements. Engine oils meeting API SJ requirements can be used in cases where the vehicle manufacturer recommends SH class or earlier..

API SH class. Motor oils for gasoline engines since 1994.

The class was adopted in 1992 for engine oils recommended since 1993. This class is characterized by higher requirements compared to the SG class, and was developed as a substitute for the latter, to improve the anti-carbon, antioxidant, anti-wear properties of oils and increased protection against corrosion. Motor oils of this class are intended for use in gasoline engines of passenger cars, vans and light trucks in accordance with the recommendations of their manufacturers. Engine oils of this class have been tested in accordance with the requirements of the Chemical Manufacturers Association (CMA). Engine oils of this class can be used when the vehicle manufacturer recommends class SG or earlier..

API class SG. Motor oils for gasoline engines since 1989.

Designed for use in gasoline engines of passenger cars, vans and light trucks. Motor oils of this class have properties that provide improved protection against carbon deposits, engine oil oxidation and engine wear in comparison with previous classes, and also contain additives that protect against rust and corrosion of internal engine parts. SG engine oils meet API CC diesel engine oils and can be used where SF, SE, SF / CC, or SE / CC are recommended.

API class SF. Motor oils for gasoline engines since 1980 (obsolete class).

These engine oils were used in gasoline engines manufactured in 1980-1989, subject to the recommendations and instructions of the engine manufacturer. Provides enhanced oxidation stability, improved wear protection compared to baseline SE lubricants, and better protection against carbon deposits, rust and corrosion. Engine oils of class SF could be used as replacements for previous classes SE, SD or SC.

API Engine Oil Grades: Diesel Engines

API class CI-4 (CI-4 PLUS). New performance class for diesel engine oils. Compared to API CI-4, the requirements for the specific soot content, as well as volatility and high-temperature oxidation, are increased. When certified in this classification, the engine oil must be tested in seventeen motor tests..

API class CI-4. The class was introduced in 2002. These engine oils are used in modern diesel engines with various types of injection and pressurization..

Engine oil corresponding to this class must contain appropriate detergent and dispersant additives and has, in comparison with the CH-4 class, increased resistance to thermal oxidation, as well as higher dispersing properties. In addition, such motor oils provide a significant reduction in engine oil waste by reducing volatility and reducing evaporation at an operating temperature of up to 370 ° C under the influence of gases. The requirements for cold pumpability have also been strengthened, the resource of clearances, tolerances and motor seals has been increased by improving the fluidity of the motor oil..

API CI-4 class was introduced in connection with the emergence of new, more stringent requirements for the ecology and toxicity of exhaust gases. These requirements apply to engines manufactured from October 1, 2002..

API class CH-4. The class was introduced on December 1, 1998. Motor oils of this class are used in four-stroke diesel engines that operate in high-speed modes and comply with the requirements of the norms and standards for exhaust gas toxicity adopted in 1998.

API CH-4 motor oils meet the stringent requirements of both American and European diesel engine manufacturers. The class requirements are specially designed for use in motors running on high quality fuels with a specific sulfur content of up to 0.5%. At the same time, in contrast to the API CG-4 class, the resource of these engine oils is less sensitive to the use of diesel fuel with m sulfur more than 0.5%, which is especially important for the countries of South America, Asia, Africa..

API CH-4 engine oils meet increased requirements and must contain additives that more effectively prevent valve wear and the formation of carbon deposits on internal surfaces. Can be used as a substitute for API CD, API CE, API CF-4 and API CG-4 engine oils in accordance with the engine manufacturer’s recommendations.

API Class CG-4. The class was introduced in 1995. Motor oils of this class are recommended for four-stroke diesel engines of buses, trucks and tractors of mainline and non-mainline types, which are operated under increased loads, as well as high-speed modes. API CG-4 engine oil is suitable for engines that use high-quality fuels with a specific sulfur content of not more than 0.05%, as well as in engines for which there are no special requirements for fuel quality (specific sulfur can be up to 0.5%).

Automotive oils certified according to API CG-4 class should more effectively prevent wear of internal engine parts, formation of carbon deposits on internal surfaces and pistons, oxidation, foaming, and soot formation (these properties are especially needed for engines of modern main-line buses and tractors).

API CG-4 class was created in connection with the approval in the United States of new requirements and standards for the ecology and toxicity of exhaust gases (1994 revision). Motor oils of this class can be used in engines for which API CD, API CE and API CF-4 classes are recommended. The main drawback limiting the massive use of this class of motor oils, for example, in Eastern Europe and Asia, is the significant dependence of the motor oil resource on the quality of the fuel used..

API class CF-2 (CF-II). Automotive oils designed for use in two-stroke diesel engines that are operated in difficult conditions.

The class was introduced in 1994. Motor oils of this class are usually used in two-stroke diesel engines that operate under high stress conditions. API CF-2 oils must contain additives that provide enhanced performance protection against wear on internal engine parts such as cylinders and rings. In addition, these oils should prevent the accumulation of deposits on the internal surfaces of the engine (improved cleaning function).

API CF-2 certified engine oil has improved properties and can be used in place of earlier comparable oils, subject to the manufacturer’s recommendation.

API class CF-4. Engine oils for use in four-stroke diesel engines since 1990.
Motor oils of this class can be used in four-stroke diesel engines, the operating conditions of which are associated with high-speed modes. For such conditions, the requirements for the quality of oils exceed the capabilities of the CE class, therefore CF-4 engine oils can be used instead of CE oils (subject to the appropriate recommendations of the engine manufacturer).

API CF-4 motor oils must contain appropriate additives that reduce the waste of the car oil, as well as protect against carbon deposits in the piston group. The main purpose of motor oils of this class is the use in diesel engines of heavy-duty tractors and other vehicles that are used for long-distance trips on highways.

In addition, these engine oils are sometimes assigned the API CF-4 / S dual grade. In this case, subject to the availability of the appropriate recommendations of the engine manufacturer, these oils can also be used in gasoline engines..

API class CF (CF-2, CF-4). Indirect injection diesel engine oils. Classes were introduced from 1990 to 1994. A hyphenated number means a two- or four-stroke engine.

Class CF describes engine oils recommended for use in diesel engines with indirect injection, as well as other types of diesel engines that run on fuels of various qualities, including those with increased sulfur (for example, more than 0.5% of the total mass).

CF engine oils contain additives to better prevent piston deposits, wear and corrosion of copper (cm copper) bearings, which are important for these types of engines, and can be pumped in the usual way, as well as with a turbocharger or compressor. Engine oils of this class can be used where the CD quality class is recommended..

Engine manufacturer approval

This is a specific quality standard for engine oil, for which all parameters are determined that the car manufacturer considers mandatory when using such a car oil in its engine. Many car manufacturers develop their own standards and requirements for car oil for each engine (or line of those). At the request of car oil manufacturers, the necessary research and tests are done, as a result of which a specific brand of oil from a specific manufacturer is allowed for use in a specific engine. All this is issued with a certificate, and only after that the manufacturer of the car oil has the right to write the approval of the car manufacturer on the label of this particular oil (see Fig.). We emphasize right away that according to the description given, it is impossible to determine the admission to your car engine, the admission must be looked at in the car description (for example, in the service book, manual, documentation, etc.).

How often to change the engine oil?

a) change the oil at least once a year;

b) take into account the coefficient of the operating mode of the car: urban mode (on synthetics – 10 thousand km, on semisynthetics – 8 thousand km), track mode (on synthetics – 13 thousand km, on semisynthetics – 10 thousand km). In worn-out engines, it is also desirable to change the oil more often, since the operating conditions of their mechanisms are more severe and more hot gases enter the engine crankcases, which are a source of accelerated oxidation;

c) by visual inspection of the oil: take oil on your finger from the tip of the dipstick and rub it between your fingers, if there are soot particles on your fingers, dirt – the oil must be changed;

d) odor: rancid-fried odor signals that the oil is out of date. For experience, we recommend checking the smell of the oil after changing it and throughout the entire period, so that a clear picture is formed;

e) do not “get fooled” by the oil change intervals recommended by the automaker!

Time does not stand still, and it is absolutely obvious that the era of “eternal” cars is far behind. It has long been not profitable for automakers to produce cars that do not break down for decades, because they need to somehow maintain their developed service infrastructures, as well as stimulate consumers to buy new cars..

Therefore, the car manufacturer, oddly enough, does not care at all about the “longevity” of the engine in the long term when calculating the recommended oil change interval. It is important for him how the engine will work during the factory warranty period, and it is absolutely not important what will happen to the engine next. Moreover, it is beneficial for the manufacturer that after the end of the warranty period, the owner of the car often visits the company service or thinks about buying a new car as soon as possible. So, for an automaker, a service interval is a marketing concept, and the main task in its calculation is to ensure the minimum costs of warranty service with the maximum attractiveness of the car for a potential consumer..

How justified it is in the CIS – judge for yourself. How often to change the oil in your engine is up to you.

The main idea of ​​this article. the manufacturer’s recommended service interval. not always a perfect car maintenance plan.

Then pour some kind of non-additive, low-viscosity – a spindle, for example. And, in pneumatic impact wrenches, if I’m not mistaken (at least what I’ve seen), oil is regularly buried in special. hole. And, when using a lubricator, a low viscosity is needed so that a sufficient amount of oil is transferred by air to the rubbing parts. And, the motorboat has a viscosity of about 100 cSt (he brought the har-ki himself). A, you need about 10 cSt

When working with any pneumatic equipment, it is necessary to ensure that purified air, which is enriched with oil particles, is supplied to the system. The filter copes with the first task, but the second requires a lubricator for the pneumatic tool. This device dilutes the airflow with oil during the spraying process, which greatly extends the life of the entire equipment and reduces wear. This is especially important for those who have to regularly resort to the use of pneumatic devices (workshop employees, service stations, construction crews, etc.).

Modern lubricators have an autonomous design, their system allows you to calibrate the supply of lubricants during operation; thus, the pneumatic tool receives the required amount of fluid. During operation, the oil level in the filling container can be monitored. During operation, it is important to use those types of consumables that the manufacturer recommends: the use of low-quality or simply unsuitable oil leads to malfunctions not only of the equipment, but also of the lubricator itself.

The question in the title can be classified as eternal, that is, those about which motorists will argue to the point of hoarseness as long as the power units that need this technical fluid are in use. Of course, it is impossible to say unequivocally that only mineral, semi-synthetic or synthetic oil should be poured into a car engine – there are too many factors to consider when choosing it. Today we will consider all the possible options that can affect the choice of lubricant for the “heart” of the machine..

To begin with, let’s remember why, in fact, the engine needs oil. It performs several useful functions: it lubricates the rubbing surfaces of engine parts, protects them from corrosion, removes heat in the places of friction of parts of the power unit, reduces shock loads, and, finally, serves as a “detergent”, washing out all the debris accumulated in the engine casing during its exploitation. Now we will build on what types of oil mankind has invented in order to protect the power plant of the machine from all of the above troubles.

The first motor oil was produced naturally from petroleum feedstocks. It is the most “natural” lubricating fluid, the composition of which is rich in natural hydrocarbons. Unfortunately, these natural components of the oil are highly unstable, changing their properties under the influence of external factors, such as ambient temperature. The first engines that used mineral oil suffered greatly from the effects of temperatures, as a result of which the technical fluid could not perform its main functions for a long time, and needed to be replaced frequently, which in itself did not please car owners. With the development of chemistry, scientists have figured out that it is possible to stabilize the properties of mineral motor oil with the help of special substances – the so-called additives. They began to be actively added to the composition of the oil, but although the expected effect was, it also turned out to be short-lived. And all because the additives added to the lubricating fluid under the influence of all the same factors collapsed very quickly, extending the life of the “mineral water” for a short time.

A real breakthrough in the “oil” business was the invention of synthetic technical fluids for engine lubrication. Obtained by the synthesis of hydrocarbons, these oils were distinguished by greater resistance to unfavorable factors, did not require, due to their stable composition, many additives inherent for “mineral water”, and, most importantly, significantly extended the life of the engine.

Then a third type of motor oil appeared – semi-synthetic. It was created by mixing bases of synthetic and mineral oils in a 30/70 proportion (some semi-synthetic oils are based equally on “synthetics” and “mineral water”). This oil is the “golden mean”, as it has absorbed the best properties of the other two lubricants.

Talking about which oil is better to fill in a car engine, you need to remember a few more of its parameters that need to be considered when choosing this technical fluid. These include viscosity (the ability of an oil to become thinner or thicker under the influence of certain temperatures), the presence of additives and the approval of an automobile manufacturer.

It cannot be said that some oil is better, and some worse – for one type of engine, for example, “mineral water” is suitable, and the other will work like clockwork only on “synthetics”. As a rule, mineral motor oils are filled into older engines (carburetor). Modern injection engines (it doesn’t matter if a gasoline or a diesel engine in a car) of new cars is best tolerated by synthetic oil – it is this oil that is poured into the engines of cars while still on the conveyor. But in the same modern engines, with an increase in mileage, such a property as increased waste (degree of combustion and oil consumption) appears. To reduce the degree of waste, semi-synthetic oil is used. Thus, we came to the conclusion: mineral water – for engines of old cars (they can work on synthetics and semisynthetics, but what’s the point of paying more?), Synthetics – for motors of completely new cars, semisynthetics – for units of new, but already passed a certain kilometers (from 60 to 90 thousand km) of cars.

But it was we who decided on what types of oils to choose in terms of chemical composition under ideal conditions. In fact, the process of choosing an oil for a particular engine is a little more complicated. First of all, you need to consider which oils the manufacturer recommends. Information about this can be found in the car manual, but if you bought a used car and there is no “manual” for it, then data on the types, brands and viscosity characteristics of engine oil can be found on the Internet, on the websites of the automaker.

As a last resort, you can call the dealership that sells cars of your brand and check all the parameters with a consultant. Then you need to determine which oil was filled from the factory (if the car is new) or the previous owner of the car. In modern cars, as mentioned above, synthetic oils are used, while used cars in the engine, most likely, are filled with “semi-synthetics” or, if the device is rare, “mineral water”. Having determined what composition and viscosity the oil has already been used in the unit of your car, you can select the brand.

Currently, the automaker does not name specific brands of oils that they pour into the engines of their cars, telling customers that there is branded oil (for example, “Mercedes” or “BMW”).

They do this because they want to keep the owner of the car on the service “needle” for as long as possible, selling him “branded” oil at a price much higher than it is sold by the spruce plant of technical fluid. Therefore, the task of the motorist is still to find out the specific brand of oil in order to save his money. In addition, it is not at all necessary to pour oil of a certain brand into the engine of your “iron horse” – for sure there are a lot of analogues on the market, which, perhaps, will suit you more on the “price – quality” scale. Indeed, the main thing in oil is not the brand, but its chemical composition (mineral, synthetic or semi-synthetic) and the degree of viscosity.

Based on all of the above parameters, you can determine which type of oil is suitable for your particular engine..

GOST and TU

Previously, in the Russian Federation, the compliance of engine oil with GOST requirements was a prerequisite. Today, the state standard has given way to some technical specifications, which are practically not standardized, since each manufacturer defines its own parameters..

An example of an oil that meets the GOST standard

Standardization according to GOST standards, from the point of view of the “Western tycoons” of the market economy, is a voluntary and unnecessary business..

International Lubricant Standartization and Approval Committee

Note that the International Committee for the Approbation and Standardization of Lubricants has proposed its own system that allows the layman to independently determine which is the best oil for the engine of his car..

Example of an ILSAC compliant oil

The IL SAC classification in practice turned out to be an attempt to introduce one universal standard that combines the North American and Western European classification.

Association des Constracteurs Europeens des Automobiles standard

The European ACEA standard is close to the overseas analogue. In this case, the letters mean belonging to the class of machines and the type of their power units.

An example of an ACEA oil

• A – passenger vehicles equipped with a diesel engine;
• B – cars with a gasoline engine;
• С – commercial vehicles;
• E – heavy duty trucks.

What oil is better to fill in the engine

What brand of oil is best for the engine? This question is of interest to absolutely all car owners, regardless of length of service and driving experience. A huge range of motor oils, which is constantly being replenished, requires special scrupulousness in choosing the right formulation..

Of course, the change of lubricant can be entrusted to the specialists of the technical center by paying a certain amount for this service. For those who wish to independently understand this procedure, we recommend that you read this article to the end..

First of all, you need to determine which oil is best to fill in the engine. The answer can be found only by understanding the classification of the corresponding product..

Experts distinguish several criteria for the selection of a lubricant. Among them:

• washing ability;
• viscosity;
• energy saving;
• resistance to corrosion, oxidation and wear.

Society of Automotive Engineers Standard

The most famous is the international SAE standard. According to this marking, the first and second numbers give information about the viscosity of the motor oil at low and high temperature operating conditions, respectively..

The difference between these indicators gives an idea of ​​the temperature range in which the substance retains the declared characteristics. However, it does not provide complete data on all lubrication parameters..

Main characteristics

All the markings mentioned, among other things, take into account and describe the main performance indicators of the grease. Therefore, we will dwell on them in more detail, which will help to figure out which oil is better to fill in a new engine..

Classification

Today, different classification systems are used to determine which engine oil is best to pour into the engine..

Viscosity limit

The low viscosity of the lubricant often causes a decrease in pressure in the internal combustion engine systems, and also provokes the formation of leaks in the pipelines of the car. On the other hand, excessive viscosity causes additional loads on power units, which reduces the working life of units and parts..

Therefore, when choosing a car oil, one should be guided by the viscosity parameters that are recommended by the automaker of a particular vehicle model. Make sure that the lubricant meets the specified standards, because even the slightest discrepancy in the letter or number of the marking can lead to a malfunction of the power unit..

So, if the car is equipped with a pumping turbine, then the lubrication must be designed to work in turbocharged engines. Otherwise, the resource of the turbine is sharply reduced, and the oil consumption increases..

An example of the viscosity of different oils at temperature 20

Cars equipped with particulate filters require the use of specialized lubricants, which are distinguished by minimal impurities and sulfur. Other lubricants, burning during operation, clog filters very quickly, disabling the entire system..

We also note the fact that it is impossible to use oil oriented to use in modern high-speed power plants if the vehicle is aggregated with a low-speed internal combustion engine. Otherwise, expect a drop in pressure in the lubrication system, and also be prepared for leaks in seals and / or oil seals..
