Before talking about classification motor oils By ACEA, we will tell a little about the organization itself.
ASSOCIATION DES Constructeurs Europeens De L'Automobile) (Association of European Car Manufacturers) was organized back in 1991. The head office of the Association is located in Brussels. In addition, in 1995 and 2004, Acea opened additional offices in Tokyo and Beijing.

It is noteworthy that the Board of Directors of the Association represent top managers of leading autocompany: BMW Group, Porsche AG, DAF Trucks NV, PSA Peugeot Citroën, Daimler AG, Renault SA, Fiat S.P. A, SCANIA AB, Ford of Europe GmbH, Toyota Motor Europe, General Motors Europe AG, Volkswagen AG, Jaguar Land Rover, AB Volvo, Man Nutzfahrzeuge AG.
Total 15 representatives of autocompany. Their main goal is to study and improve the operational quality of cars, including through the use of high quality supplies, for example, motor oils.
So in December 2008, Acea introduced an updated and relevant classification of motor oils "ACEA 2008 European Oil Sequences for Service-Fill Oils". The classification was supplemented with more perfect classes C4 and E9. In addition, corrections were introduced to the oils in the stability of oxidation and the composition of the oils. All this was done in order to highlight oils with high ecology and energy saving. Energy saving is provided by lower oil viscosity at extreme temperatures.
Currently, the classification of oils according to ACEA 2008 is drawn up as a document for 3 conventional modes of motors: A, B and E. These are groups accordingly mean that oils are intended for gasoline, light diesel and severely loaded diesel engines.

At the same time, each class is also divided into categories of various levels of operational properties:

Four for gasoline and lungs diesel engines (A1 / B1, A3 / B3, A3 / B4, A5 / B5);
Four specially for gasoline and light diesel engines equipped with catalytic doctor systems (C1, C2, C3, C4);
Four for heavy loaded diesel engines (E4, E6, E7, E9).

Motor Oil Class ACEA: Motor oils for gasoline engines and diesel engines of passenger cars, vans, minibuses

	The main disadvantage of this group of oils is high ash content and low environmental friendliness.
A3 / B3.	Oil resistant to destruction intended for use with an increased replacement interval in gasoline and diesel engine. The possibility of applying as all-season oils, slightly best features By environmentally friendly than the previous group.
A3 / B4.	Oil resistant to destruction intended for use with an increased replacement interval in gasoline and diesel engine. Oils used for injector engines.
A5 / B5.	Oil resistant to destruction intended for use with an increased replacement interval in gasoline and diesel engine. Low viscosity makes this group of oils most preferable to use in engines, where it is permissible to use such an oil.

Motor Oil Class E ACEA: Motor Oils for Heavy Diesel Engines

	Recommended for use in high-turn diesel engines that meet the requirements of EURO-1, EURO-2, EURO-3, EURO-4 and EURO-5 by emission toxic substances and working in particularly severe operating conditions. Oils are used for engines without particulars, as well as for some engines equipped with exhaust gas recirculation systems (EGR) and selective catalytic reduction system (SCR) to reduce the level of nitrogen oxides NOX in exhaust gases.
	Oils providing a high level of stability of lubricating properties depending on operating temperatures and the deadline for use. Having minimal ash content. As a result, oils are not so much darker, do not contaminate the emissions of the atmosphere, do not lose low viscosity, do not pollute the cavity of the engine. Recommended for use in high-speed diesel engines that meet the requirements of EURO-1, EURO-2, EURO-3, EURO-4 and EURO-5 on emissions of toxic substances and working in particularly severe operating conditions, for example, significantly increased oil replacement intervals in accordance With the recommendation of the automaker. Oils are applicable to engines equipped with exhaust gas recirculation systems (EGR) with / without summary filters (DPF), as well as for engines with a selective catalytic reduction system (SCR) to reduce the level of nitrogen oxides NOX in exhaust gases. The quality of the E6 is directly recommended for the engines with the particulate filters (DPF) in combination with a small diesel fuel.

E9 is directly recommended for engines with particulate filters (DPF) and designed to work in combination with a small diesel fuel.

According to the results of the table, it is necessary to say that it is impossible to choose oil based only from your preferences and speculations. Here it is necessary to pay attention to your type of engine and on the recommendation to your machine.
So the use of high ash oil when using a catalytic neutralizer can lead to its failure.
And this means that the oil must be applied to the recommended, and not the first "one you caught under the arm".

ACEA Standard (Association of European Car Manufacturers), represents the certification of motor oil for use and work, and takes into account the requirements of 15 automakers (BMW, DAF, Daimler-Crysler, Fiat, Ford, GM-Europe, Jaguar Land Rover., MAN, PORSHE, PSA Peugeot Citroen, Renault, Saab-Scania, Toyota, Volkswagen, Volvo).

In December 2008, Acea introduced the updated and most recent classification of motor oils "ACEA 2008 European Oil Sequences for Service-Fill Oils", in which new C4 and E9 classes appeared, and adjustments for the requirements for oils of antioxidant stability and item The composition of oils due to energy saving and environmental policy.

The new classification divides oil into three classes by type of engines: A (gasoline), B (light diesel) and E (severely loaded diesel engines).

Each class is divided into categories of various levels of operational properties:

• Four for gasoline and light diesel engines (A1 / B1, A3 / B3, A3 / B4, A5 / B5);
• Four specially for gasoline and light diesel engines equipped with catalytic doctor systems (C1, C2, C3, C4);
• Four for heavy loaded diesel engines (E4, E6, E7, E9).

As follows from the name, the ACEA organization was created by major automotive concerns to coordinate the production and adoption of uniform product quality standards. Car enthusiasts are primarily interested in classification of ASEA oils - as a rule, the corresponding digital-letter codes are written on the CO's canices and help the buyer to choose the desired product.

About standard

Initially, a similar association was formed in the United States (API), but the difference in the design details of cars pushed the Europeans to the base of ASEA. In 1996, the first classification of ASE engine oils was determined, in which individual sections were devoted to lubricant materials for gasoline machines and. Later, in 2008, hydrocarbons were launched, suitable for both categories of engines, and the documentation was edited. Now the product is marked: ASEA A1 / B1, AEA A3 / B3, etc., and t. "A" characterizes lubricant for gasoline motor, "B" - for diesel.

What are the numbers and letters in the class of ASEA

Now let's talk about the meaning of digital-letter codes in the classification of ASE engine oil.

Classes

According to the composition and field of application, these petroleum products are divided into three classes: A / B, C and E.

1. The letters a / in canister say that inside lubricantrecommended for and low-loaded diesel engines.
2. C - oils for diesel and gasoline injection engines with environmentally friendly properties and complementary filters for neutralization harmful substances when exhaust.
3. E is the category of oils intended for heavy vehicles with a diesel engine. In the last edition, the discharges are added E6 and E7.

Figures from 1 to 7, ascribed to the letters, refine the properties of the lubricant and its composition.

Documentation

In general, the ASEA documentation reminds Russian GOST and consists of the classification of motor oils, requirements for them, describing the tests carried out, as a result of which a particular product was released under the auspices of the community. Observice of ASA standards is monitored by the European Commission EelQMS. Each manufacturer seeking to obtain motor oil from the Association of European Auto-Engineers is obliged to conduct research in laboratories recommended by association and prove that its products meet all specifications.

Description of classes and categories

A1 / B1 - all-season oils with a moderate viscosity for gasoline and diesel engine (in machines with small loading). Such a hydrocarbon can be changed for two years. However, it is not suitable for all engines, and not recommended to apply it in a hot climate, where the temperature approaches the indicator above +25.

A3 / B3 - also applies to both gasoline and diesel engines (in light transport) with the only difference that this case We are talking about engines with high power. This species Lubricants are all-season in moderate climate and for a long time does not require replacement.

ASEA A3 / B4 engine oil is almost the same look as A3 / B3, but designed for newer cars with an injection fuel supply system.

ASEA ASA A5 / B5 oil is a low-grade type for machines with an injection fuel supply system. Its lubricants can not be called all-season - they are or harsh climate, and some engines are contraindicated.

C1 is a category for gasoline and diesel injector DVS with a reduced content of phosphorus and sulfur salts. Focused on savings and decay to neutral substances when exhaust. Has low viscosity to approach powerful engines With small gaps between the details. Such petroleum product cannot be used if the machine is pretty outdated or previously worked on a more aggressive lubricant.

C2 - hydrocarbon with higher, in comparison with the previous category, phosphate and sulfate content. Also, lubricants are designed for economical injection engines with exhaust filtration system.

C3 - the same in composition, as well as C2, but a more viscous type of oil - for operation in the southern climate.

C4 - in turn it is similar in composition with C1, but has a greater viscosity.

E4 - oil intended exclusively for diesel engines of large trucks. It helps to neutralize the N2O, even if a special filter is not installed, prevents the formation of particulate sediments.

E6 - practically the same as E4, but for cars equipped with filtration system.

Motor ASEA E7 oil is an improved version of E4 for machines without filters. Cleans piston cylinders and turbochargers. Lubrication does not require.

Perhaps you also met oils with marks on the A1 / V1-04 or 96 canister. These additional numbers are sent to the editorial board of ASEA. That is, it is possible to find out the properties of this product in the species ACEA classification for 2004 or 1996.

To properly choose a lubricant for your engine, oil tables on ASA are not enough: you need to carefully read specifications Machines, examine related documentation (tolerances of the American Oil Institute - API, SAE - classification by viscosity, etc.).
