What is acea A5 B5. Decoding Oil Classification by ACEA

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 everything oil fluids By their properties and parameters.

The classification of ACE oils includes three categories:

1. The first includes oils intended for passenger cars, vans, minibuses.
2. The second category includes lubricants, including a catalyst that restores spent gases.
3. 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 the classification of motor oils by ACEA there is 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 his 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 power units that are not 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. for more information On the form and characteristics of the car. This standard is designed to simplify the driver's 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.

Acea. - Association created by the largest European manufacturers ( Alfa Romeo., BMW, Citroen, Peugeot, Fiat, Renault, Volkswagen, Daimler Benz, British Leyland, DAF).
It was founded as a result of the CCMC merge with ATIEL. CCMC specification, which is currently replaced by ACEA, classify products like G for gasoline, PD for lungs and D for heavy diesel engines.
ACEA Specifications were designed to improve quality, performance and better attitude towards the surrounding environment.
Acceptance of ACEA specifications implies:

• Introduction to the operation of new innovation materials, in comparison with the currently used
• Analysis and certification of quality levels of each used formula
• The obligation of manufacturers does not make changes to the approved formulas
• ISO 9001/2 Factory Certification
• Consent of manufacturers with ATIEL standards, organization, together with CCMC identifying methods and parameters of the basis of ACEA certificates

Tests required by ACEA specifications are added to the CCMC formulated and make them more stringent.

The following letters classly class types:
[A] - gasoline engines
[B] - Light diesel engines
[C] - Fangs with devices to reduce the number of exhaust
[E] - Heavy diesel engines
Digital categories indicate various methods Applications associated with a certain class of engines specified by letters. The latest update of the ACEA specifications occurred in February 2002.
Responsibility for choosing the desired ACEA category lies on the engine manufacturer.
Oils addressed to a specific category can also comply with the requirements of another, but the oil of a certain category and class should be poured into specific engines.
The reference for the year is only for industrial necessities, giving information about the level and quality of the materials used. More than fresh editions of the specifications mean that new tests were conducted or new requirements were introduced into the category. At the same time, the editors retain backward compatibility, new will always fully maintain the level of old, except when a new category is introduced.

Motor oils by definition cannot comply with the Unified Standard. Various engines and types of gearboxes, operating conditions - all these factors are forced to produce technical fluids with different parameters.

To consumers (automobile owners and car owners) are not combined in compatibility supplies With aggregates, it was decided to create a quality standards system.

Initially, oils were classified only by viscosity (SAE). Then the system was created quality API (American Petroleum Institute), which was used in North America.

Immediately after its introduction, the Association of European Engineers a similar classification of ACEA oils was developed, for the European market. Both standards exist in parallel, not conflicting with each other.

What does the standard say

The classification of motor oil on ACEA was designed to lobby the interests of European automakers. In addition, several concerns from the United States with branches in Europe entered the "support group".

Here is an incomplete list of founders of the Standard: BMW, Volkswagen AG, Porshe, Daimler, Land Rover., Jaguar, Fiat, PSA, Renault, Ford-Europe, GM-Europe, Crysler-Europe, Toyota, Man, Volvo, Saab-Scania, Daf. As deciphered (more precisely, what information does the standard carries in itself)?

What to pay attention to when buying a motor oil - Video Consultation

If the SAE abbreviation speaks only viscosity, then in ACEA compatibility data is laid with specific engines. And lists of compatible aggregates are agreed with car convenues - participants of the certification program.

In classification according to the ASE standard, minimal basic requirements for oil quality are laid. That is, their observance (in contrast to the selection by SAE), guarantees the trouble-free operation of the motor or gearbox. In addition, this classification provides information on the following parameters and properties:

• basic base;
• a set of additional additives;
• chemical composition;
• physical properties;
• purpose (type of fuel, load on the engine, operating conditions of the aggregate).

Marking and their meanings

The classification of motor oils by ACEA can be applied to packaging along with other standards, such as API, ILSAC and GOST.

Important! From the point of view of the consumer, this particular certificate guarantees high quality. Conditions for testing oils To obtain the ACEA specification, significantly higher, in comparison with the rest of the standards. European requirements of tougher North American, Asian and Russian.

Despite the compactness of the classifier (for example, AEA A1 / B1), there is enough voluminous information into the abbreviation. During the existence of the standard (starting since 1996), the layout of characters changed several times.

The first certification options assumed a separate labeling for gasoline and diesel engines (ACEA A or ACEA B). Starting from 2004, all oils presented to obtain admission are simultaneously tested for all types of fuel.

It makes no sense to remember abbreviations with mono tolerance, such consumables are no longer produced.

Modern oils certified at once for all types of fuel are labeled with an indication of the class by fraction: for example, ACEA A1 / B1.

Main classification of oils according to ACEA standard (including outdated)

1. Class A - certified compatibility with power plants operating only on gasoline. The content of sulfur and sulfate ash is higher than modern EURO environmental safety standards.
2. Class B - admission is suitable for heavy fuel engines. Load class on diesel force aggregate: "Light Duty", that is, light and medium. The percentage of sulfate ash is reduced to modern norms, the sulfur content is quite high.
3. Class C - Standard is designed for a fairly large line of motors. Works with gasoline engines equipped with a catalytic neutralizer, as well as with diesel engines equipped with summer filter. It is characterized by the average and low content of sulfate ash and sulfur, oil meets the high requirements of environmental safety.
4. Class E is a fairly narrow standard, intended for the powerful diesel engines working in the difficult conditions "Heavy Duty".

Detailed ACEA Classification

After 2012, ACEA introduced many additional subclasses:

• For passenger carsequipped with diesel and gasoline engines. Measures small and average load. 4 categories of Motor Oil ACEA: A3 / B4, A1 / B1, A3 / B3, A5 / B5;
• For commercial diesel engineering and heavy trucks of category from C1 to C4, the engine must comply with EURO 4 environmental standards;
• For motors working on any fuel, in the presence of cleaning systems in the design exhaust gases (Catalyst, DPF) - another 4 Categories: E4, E6, E7, E9.

The last figure denotes a consistent increase in class and compatibility class. If in power installation It is prescribed to use ACEA A3 / B3 oil, then the ACEA A5 / B5 can be poured into it. No backward compatibility.

Details about Classes ACEA - Video

The most sought-after categories with decoding:

• A1 / B1 - stable to bundle oil, are designed to prolong the replacement interval. Minor friction losses. The main use is gasoline and diesel engines working on small loads. The classifier is not universal - you should study the tolerances of the car manufacturer.
• A3 / B3 - designed for petrol engines With a high degree of forcing, including turbine. When operating with diesel fuel, on the contrary, used on low-loaded DVS. Universal weather exploitation, increased replacement intervals.
• A3 / B4 - Development of the previous specification: Work is allowed on turbocharged diesel engines with high forcing. Have backward compatibility with A3 / B3.
• A5 / B5 is a relatively fresh standard that has enjoyed advantages (more precisely - requirements) of previous classifications. In addition to environmental tolerances, oil refers to the category of highly economical. In addition, the lubricant is practically not consumed "on the Ear". It has backward compatibility with previous classes. The exception is only the lack of compatibility with specific engines (indicated in the instructions for regulatory work).

Important! If there are several quality standards on packaging with motor oil, it is better to navigate exactly on ACEA.

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 of passenger cars in ASA are 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 included all previously designed classes A and B (until 2004 a - auto-oil for gasoline engines, in - for diesel). To date, there are four classes in this category: A1 / B1-04, A3 / B3-04, A3 / B4-04, A5 / B5-04.

FROM - A new class - auto-oil for diesel and gasoline engines, corresponding to the latest tightened requirements for the ecology of EURO-4 exhaust gases (as amended in 2005). These engine oil are compatible with catalysts and diesel filters. Actually, it is the innovation in European environmental requirements and caused the reconstruction of the 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.
