Marking of motor oils. Classification of ilsac motor oils which means GF 5 in engine oil

The classification of motor oils in ACEA allows motorists and professionals to navigate the market and choose suitable products from tens of thousands of proposals. Each high-quality oil is tested for compliance with the International Standard.

ACEA (Association Des Constracteuis Europen Des Automobiles, Association of European Auto-Engineering) is a large organization consisting of the most authoritative car manufacturers in Europe. ASEA standards are international. Oil tolerance (ACEA C3, C2, A2, B3, etc.) indicates the applicability of the composition to the components with those or other characteristics.

About standard

Initially, the world existed the API specification (American Petroleum Institute). However, other operating conditions of cars in Europe, continuous development of technologies, constructive differences from American cars forced manufacturers to create their tolerances of motor oils. In 1996, the first edition of the European Association standards was published. Soon the standard became international.

In 2004, the classification has changed. If the standardization was previously passed separately under diesel and gasoline engines, since 2004, oil brands were combined. ASEA A1 / B1, ASEA A3 / B4, and so on. The first pair of letter / digit means the level of characteristics of the gasoline motor, the second - diesel. Oils applicable only for diesel engines or only for gasoline DVS (for example, ASEA A3, AEA A5 or ASA B5), are not produced today.

The ASEA specification is divided into 4 groups:

In each group there are 5 categories indicating numbers from 1 to 5. Lubricants from them differ operational properties, compositions.

Marking and their meanings

The editorial office stands out:

• 4 categories of lubricants for gasoline engine and diesel engines of passenger cars / low-loaded equipment (ASEA A3 / B4, A1 / B1, A3 / B3, A5 / B5);
• 4 categories - for diesel engines of heavy equipment (from C1 to C4);
• Grade 4 - for motors with cleaning systems exhaust gases (E4, E6, E7, E9).

Below you can find the decoding of the ASEA specification for different engines. For convenience, the description is divided into groups for purpose.

Class A / B: for gasoline μs and low-loaded diesel engines

A1 / B1 - compositions for gasoline and diesel engine, in which an extended oil replacement range is provided. Provide low friction when high temperatures and shift speeds up to 3.5 MPa / s.

A3 / B3 - Lubricants for high-performance gasoline engines, diesel engines passenger cars. Designed for an extended replacement interval, use throughout the year, providing normal conditions the work of the DVS In severe conditions for him.

Asea A3 / B4 - for engines with direct fuel injection. Replace A3 / B3 oils. ASEA A3 / B4 class products are energy-saving, reduces fuel consumption.

ASEA A5 / B5 - for high-performance diesel engines, gasoline engines. Provide low friction coefficient at high temperatures, high shift speed. You can apply instead of class ASA A3 / B4 lubricants.

Class C: for internal combustion engine with sump filters and catalytic neutralizers

C1 - Composition for motors with summary filters, three-component catalytic neutralizers. Extends the service life of the exhaust gas purification system. Provides normal working conditions in complex operating modes: at high temperatures, shift speed up to 2.9 MPa / s.

C2 - oil for high-performance diesel engines, gasoline engine. Differs from the previous type of content of various substances.

C3 - Low sulphate lubrication. It has a low viscosity at high temperatures, shifts speed up to 3.5 MPa / s.

C4 - Low sulphate lubricants, low sulfur and phosphorus. Have a minimal viscosity at high temperatures and shift speeds up to 3.5 MPa / s.

Class E: For powerful diesel engines, special equipment

E4 - compositions that ensure the purity of the pistons. It is recommended to apply for diesel engines that meet EURO-1 ecology standards working in heavy conditions (High loads, long continuous operation). Substances are applicable to the technique in which the extended service interval is provided. This specification of motor oil does not imply compatibility with the particulate filters. Compatibility with recycling system must be specified for each specific auto model.

E6 - lubricants compatible with the particulate filters, exhaust recycling systems. Recommended for cars operating on low sulfur fuel.

E7 - compositions for DVS without particulate filters, but with exhaust recycling systems, reduce nitrogen oxide levels.

E9 - products with a similar previous scope of application, but with more stringent requirements for the composition. Used on the most modern machines.

Other standards: differences and similarities

The classification of ASEA is not the only one in the world. The standards of API and ILSAC are also generally accepted. In the CIS countries, lubricants are brought into line with GOST. But this standard does not use when choosing an oil, trusting international classifications.

API.

The American Oil Institute shares all the foundations on which lubricants are made for 5 groups. They are shown in the table below.

S - Quality categories for gasoline engines; depending on the basis and package of additives, conclusions are made regarding the applicability of the finished composition to the machines of certain annual releases. ASEA Classification divides all lubricants into 4 categories, API - by 2:

• S - Quality categories for gasoline engines;
• C - standards for diesel engines.

Each standard contains 2 letters. The first indicates a group (s or c), the second is the year of production of the car to which the oil is applicable.

API is an American standard, but it is recognized worldwide. Therefore, the class on this standard can give European oil.

Ilsac

ILSAC (International Committee on Standardization and Approbation of Motor Oils -INTERNATIONAL LUBRICANT STANDARTIZATION AND APPROVAL COMMITTEE) - an organization established by American and Japanese Associations of car manufacturers (Aaama and Jama). It is clear from the name that it is engaged exclusively by motor oils in contrast to the associations described above. The Committee tightens existing oil tolerances on the basis of its own studies.

Increased requirements are presented to the following characteristics:

Today, the classification of oils divides all the compositions for 5 categories:

Classification of ASAA oils, API, ILSAC - an important criterion for choosing a car for a car. It is always necessary to compare the requirements for the manufacturer of the car with the lubricant marks indicated on the package.

Strictly speaking, engine oils are classified according to viscosity-temperature properties and quality level. In the first case, you need to talk about the system sAE classificationwhich is generally accepted all over the world. But if you try to separate oils by grades of quality, everything looks not entirely definitely. One of the newly created quality standards received the name of ILSAC, and we will look at it further. Note that this standard is developing American and Japanese car manufacturers under the guidance of the International Standardization Committee lubricants (ILSAC).

As in the American API system, the ILSAC standard differs materials intended for gasoline engines and for diesel engines. But the requirements developed now are only related to gasoline engines. You do not need to be surprised, seeing the inscription "for Gasoline" on the label, whereas according to API, the material corresponds to the SJ / CF class, which has a relationship to "diesel engines" and gasoline engine at the same time. Which of the modern classification systems is more accurate (API, ILSAC, GOST), we will not argue. Note only that the later the standard was developed, the more relevant.

What is it?

In total, the ILSAC standard provides five quality classes, from GF-1 to GF-5. Note that if the engine oil corresponds to one of the specified classes, it is suitable for operation with a gasoline engine. But this does not mean that it cannot be operated with diesel engines. The ILSAC standard does not consider the requirements for oil for "diesel", which can sometimes be confused when choosing.

How to use it

The higher the ilsac oil class, the better and more modern. For example, the GF-2 class is the same as the SJ API, but provided that the material corresponds to one of the listed viscosity classes by SAE: from 0W-x to 10W-X, where x is 30-60, as well as 0W- 20 and 5W-20. The most "qualitative" class of ILSAC corresponds to the quality class API SM. But the requirements of the API standard are complemented here by the following items:

• Dynamic viscosity should be within 2.6-2.9 MPa * C;
• The material must have low foaming, volatility, good filterness at low temperatures;
• The small content of phosphorus is regulated, which, during operation, the Iridiyevy catalyst is helped with a direct injection.

As you can see, the ILSAC system is more modern than the API. Requirements tougher, it means that more confidence. Oils corresponding to the requirements of the GF-4 class, including LUKOIL. Choose the best for your car!

At the end of 2010, two new models of engine oils API SN and ILSAC GF5 are published. From October 2010, licensing began. Products with new classes appeared in our market at the beginning of 2011.

The new class SM was created by the American Oil Institute (API) together with the American Professional ASTM Association (American Society for Testing Materials) and SAE (Society of Engineers of the Automotive Industry). The differences between the SN API class from the previous SM specification are much more scaligible than the differences of the SM class from SL. The main difference between the SN API from previous API classifications in limiting phosphorus content for compatibility with modern system neutralization systems, as well as integrated energy saving. That is, the oils classified according to the API SN will approximately correspond to ASE C2, C3, C4, without an amendment to high-temperature viscosity. For the new category API SN, the lubricant committee proposed to follow the same development scheme as with earlier categories of API and ILSAC. This means that all performance features Motor oils for API and ILSAC will be equivalent to, except that the proposed requirements of the API SN do not include tests for wear on the Sequence IIIG method on the generated oils. These tests and fuel savings tests according to the Sequence Vid methodare important benchmarks for oils claiming to comply with the ILSAC GF-5 standard.

The main differences between the ILSAC GF-5 from the previous classification of GF4, in the ability to work with biofuels, improved wear and corrosion protection, greater fuel economy, improved owlart a perception with sealing materials and improved slag protection.
The requirements of the API SN and ILSAC GF5 are close enough and small oils, most likely, will be classified together in these two classifications.

Comparison of ILSAC GF-5 and API SN

Motor tests ilsac oils and API.

For motor oils of gasoline engines. One of the reasons is that aPI classification SN headed new category Motor oils called - resource-saving.

To understand that such an API SN in the resource is a saving oil, you need to deal with the API SM energy saving.

Decoding API SN and SM

When a new class API SM was developed in 2005, he received an additional specification, more precisely, it was determined in a new category of energy-saving oils at that time, in which it is still alone (API SM).

Energy Conserving. (indicated by EC, example API SM EC.) i.e. Energy saving oil, which has low-visual properties (in other words, more fluid or liquid), due to which fuel economy was achieved at least 1.5% of the similar reference API SM.

Resource Conserving. (denotes RC, example API SN RC.) and is a resource-saving oil and in this category only the classification of the engine oil API SN. The RC Specification (Resource Conserving) appeared in 2010, when the SN API.

Summing up Notes, the difference between RC from EC is the requirements for the specification. It can be said that the resource-saving oil exceeds energy saving, as it requires not only saving fuel from high-quality oil, as well as the preservation of the parts of the exhaust system, turbocharging and compatibility with biofuels.

The SN API is not completed on this. For a more correct and understandable presentation in improvements you need to simply compare aPI Specification SN and SM.

• Improved degree of protection at high temperature in cylinders
• Less than nagar sediments
• Improved compatibility S. different species Fuel
• Improved detergent
• Improved protective properties

Requirements for the ILSAC GF-5 standard are similar to the SN RC API.

In fact, the requirements for the International Asian market are sufficiently objective. If you find on japanese oil ILSAC GF-5, you may not doubt that this oil meets the requirements of the API SN RC. The absence of a resource-saving oil specification deprives its capabilities to obtain the ILSAC GF-5 standard.

ILSAC, the International Committee for Standardization and Approval of Lubricants, formed in 1992 AAMA (American Association of Car Manufacturers, Representatives Daimlerchrysler Corporation, Ford Motor Company. and General Motors Corporation) and Jama (Japanese car manufacturers Association) to determine the needs, parameters and licensing. and administering the specifications of lubricants. Together with the trilateral system (API, SAE and ASTM), Eolcs was formed, licensing and certification of engine oil. ILSAC oils often have API service symbol (donut), including energy saving designation and / or API certification sign (Starburst).

Further lists the current ILSAC sectoral standards. Before using data from tables, you should carefully examine the instruction manual vehicle. Engine oil can meet the requirements of more than one operational category.

The latest edition of the Sectoral ILSAC Standard ( GF-5.) Motor oils of automotive gasoline engines includes operational requirements Previous versions and can be used to serve previously released engines for which oils of previous categories were recommended.

Soon a new standard should be adopted - GF-6. The ILSAC GF-6 specification is currently in development and is likely to be divided into two sub-specification. ILSAC GF-6A will be fully compatible with ILSAC GF-5, but will provide better fuel economy, better defense Engine and improved characteristics while maintaining durability. ILSAC GF-6B will have the same characteristics as ILSAC GF-5A, but will allow the use of less viscosity oils, such as XW-16, using the advantages of fuel economy offered by the new SAE 16 viscosity class.

The main differences of the oils of the ILSAC category:

• low viscosity - 2.6-2.9 MPa C at a temperature of 150 ° C and a shear rate of 10 ^ 6 s ^ -1;
• small volatility (on Nok or ASTM);
• good filterness at low temperatures (test General Motors);
• low leaning to foaming (test ASTM I-IV);
• high stability to the shift (L-38 at least 10 hours) (SHEAR STABILITY);
• mandatory fuel economy (ASTM test, Sequence VIA);
• small phosphorus content (to prevent the catalyst clogging);
