ACEA (Eng. European Automobile Manufacturers Association) - Association of European Car Manufacturers. This abbreviation is denoted by the Community of Auto Producers from Europe. It includes fifteen firms producing engine oil in large volumes. Nine years ago, the community created a special standard, which allows to divide oils for cars to the subgroups, reminds GOST. SpecificationACEA classifies all oil fluids by their properties and parameters.
The classification of ACE oils includes three categories:
- The first includes oils intended for passenger cars, vans, minibuses.
- The second category includes lubricants, including a catalyst that restores spent gases.
- Oils from the third category are used in high-loaded diesel engines.
Class 1.
Any class entering the ACEA specification contains four groups of oils. Their marking consists of letters and numbers. The 1st grade includes lubricants A1 / B1, A3 / B3, A3 / B4, A5 / B5. These oils can be used for gasoline engines, low-loaded diesel engines, minibuses.
Removal designation on canister A1 / B1 have a large operational resource. Such consumables are minus, flowable. In detail to familiarize yourself with their characteristics, it is possible to look into the operational guidance attached to the car.
A3 / B3 are designed to fill in highly affiliated engines. Automal data can be used all year round. Automakers argue that they do not need to be changed.
ACEA A3 / B4 is suitable for filling in high-resistant DVS, which enclose the fuel injection system.
A5 / B5 can be used in highly affiliated motors to increase the replacement intervals. Such lubricants are sufficiently fluid, because of which they cannot be pouring into certain engines.
Class 2.
For highly affiliated motors, including the exhaust gas recovery catalyst, in classification motor oils ACEA has a special category. Oils that are included in it are used in MOX on gasoline / diesel. Lubricants prolong the operating period of soot filters and three-component catalysts.
C1 encloses the minimum number of sulfur compounds and phosphorus, have a small ash of sulfates. Oils are small, are intended to reduce the cost of fuel.
ACEA C3 for its own characteristics resemble C2, but more viscous.
C4 are similar to C1, but more viscous. The content of sulfur, phosphoric elements, the ash content of sulfates is minimal.
It is necessary to remember that the ACEA quality tolerances describe quite specialized lubricants that are intended for use in certain motors. However, this does not mean that you need to ignore the recommendations of the automaker. The manufacturer is best known which petroleum product is required to pour into its car.
Class 3.
Automas belonging to this class are marked with the letter E, poured into high-loaded motors on the diesel. They cannot be used in gasoline / gas engines. In addition to providing lubrication of parts, these consumables purify piston nodes. Commodally, they are poured into the engine, certified by Euro-1 / 2/3/4/5. Also, these lubricants increase the replacement intervals.
E4 make it possible to reduce wear of motor parts. The additive elements that are contained in them allow to reduce the formation of particulate sediments. In view of this car it is possible to apply in force aggregatesnot equipped with soot filter, but equipped with EGR, SCR. In this case, the lubricant provides a reduction in the concentration of nitrogen oxides in exhaust gases.
E6 is similar to E4, but are intended for use in power units, including soot filters.
E7 polish engine spare parts internal combustion. They provide smoothness of piston cylinders. Lubricants are poured into engines that are not equipped with soot filters. The presence / absence of ERG / SCR does not matter.
E8 are used in power units equipped with soot filters. In its characteristics, these oils are close to E7.
Selection of cars
Choosing a fresh consumator for cars, first of all, consider the recommendations of the manufacturer of the machine. Before pouring into the car, the car, differing from the recommended, be sure to consult with an employee of the service center. Remember that, the bay in the engine of the unsuitable petroleum product, you give the automaker the right to refuse you in warranty repairs.
In order not to make a mistake with the choice, you need to understand how oil labeling decryl. To be able to fulfill the labeling is not enough, it is necessary to understand what the characteristics of a petroleum product. Get acquainted with the lubricant parameters, it is possible to look into special tables.
The ACEA specification can be considered only as a source of additional information on the form and characteristics of the machine. This standard designed to simplify drivers choice lubricating fluids. For example, if the lubricants recommended by your automaker are not in stores, you can pick up the other related to the same ACEA class.
Before telling about the classification of motor oils by ACEA, we will tell a little about the organization itself.
ASCEA Association (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).

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".
Association of European Car Manufacturers ACEA (Association Des Constructeurs EUROPEENS DE L "AUTOMOBILE), represents the interests of 15 European car manufacturers and trucks and buses at the EU level. This classification establishes a new, tougher compared to CCMC, the European classification of motor oils for operational properties.

N, Daimler AG, Renault SA, Fiat Spa, Scania AB, Ford of Europe GmbH, Toyota Motor Europe, General Motors Europe AG, Volkswagen AG, Jaguar Land Rover, AB Volvo, MAN Nutzfahrzeuge AG.
In December 2008, Acea introduced an updated and most relevant classification of motor oils "ACEA 2008 European Oil Sequences for Service-Fill Oils", in which new C4 and E9 classes appeared, and adjustments were made according to the requirements for oils of antioxidant stability and elemental composition. Oils due to energy saving and environmental policies.
The classification "ACEA 2004" will act in parallel with "ASEA 2008" until December 22, 2010.
Modern classification "ACEA 2008" consists of three classes by type of engines: a, b and e (respectively gasoline, light diesel and severe diesel engines).

This is the Association of European Car Manufacturers. This organization was created to lobby the interests of automakers. One of the activities of ACEA was the issuance of requirements for the use of motor oils in engines of companies in this organization of companies.
To date, its membership is very impressive: BMW, Daf, Daimler-Crysler, Fiat, Ford, GM-Europe, Jaguar Land Rover., Man, Porshe, Psa Peugeot Citroen, Renault, Saab-Scania, Toyota, Volkswagen, Volvo.
The latest edition of the ACE motor oil classification was adopted in 2004. From this year, motor oils for diesel and gasoline engines passenger cars ASEA is combined into one category. But, due to the fact that not all the latest cars, which are classified by the new edition of ASA, can be used in engines earlier releases, manufacturers of car oils still often write on the packages of engine oil assigned earlier grades of quality according to the previous revision of 2002 .
Please note that any machine manufacturer, which uses ACEA standards in its advertising and on packaging, must necessarily conduct the necessary tests according to the requirements of the organization responsible for matching the quality of motor oils ACEA standards.
What do the numbers and letters in the class ASA?
In the latest edition of ACEA (2004), the car is divided into three categories:
A / B. - Motor oils for gasoline and diesel engines. This category includes all previously designed classes A and B (until 2004 A - Automal for petrol engines, B - for diesel). To date, there are four classes in this category: A1 / B1-04, A3 / B3-04, A3 / B4-04, A5 / B5-04.
FROM – new Class - Automal for diesel and gasoline engines that meet the latest tightened ecology requirements exhaust gases EURO-4 (as amended 2005). These engine oil are compatible with catalysts and diesel filters. Actually, it is an innovation in European environmental requirements and caused reconstruction aCEA classification. To date, there are three classes in this new category: C1-04, C2-04, C3-04.
E. - Motor oils for loaded diesel engines of heavy vehicles. This category existed from the very introduction of a classification (since 1995). In 2004, cosmetic changes were made, 2 new E6 and E7 classes were added, and two other, obsolete class were excluded.
