ACEA (European Automobile Manufacturers Association) is an association of European car manufacturers. This abbreviation stands for the European automotive community. It includes fifteen companies that produce motor oil in large volumes. Nine years ago, the community created a special standard that allows car oils to be divided into subgroups, reminiscent of GOST. SpecificationACEA classifies all oily fluids according to their properties and parameters.
ACEA oils are classified in three categories:
- The first includes oils designed for cars, vans, minibuses.
- The second category includes lubricants that include an exhaust gas recovery catalyst.
- Oils from the third category are used in highly loaded diesel engines.
Class 1
Any class included in the ACEA specification includes four groups of oils. Their markings consist of letters and numbers. Class 1 includes greases A1 / B1, A3 / B3, A3 / B4, A5 / B5. These oils can be used for gasoline engines, lightly loaded diesel engines, minibuses.
Designation of tolerance on the canister A1 / B1 have a long service life. Such consumables are low-viscosity, fluid. You can get acquainted with their characteristics in detail by looking in the operating manual that comes with the car.
A3 / B3 are designed to be loaded into high-powered engines. These motor oils can be used all year round. Automakers say they don't need to be changed frequently.
ACEA A3 / B4 are suitable for filling into highly accelerated internal combustion engines, incorporating a direct fuel injection system.
The A5 / B5 can be used in high performance engines for extended drain intervals. Such lubricants are fluid enough that they cannot be poured into certain engines.
Class 2
For high performance engines that include an exhaust gas recovery catalyst, there is a special category in the ACEA engine oil classification. The oils that it contains are used in gasoline / diesel internal combustion engines. Lubricants prolong the operating life of soot filters and three-way catalysts.
C1 contain the minimum amount of sulfur and phosphorus compounds, and have a small ash content of sulphates. Low-viscosity oils are designed to reduce fuel consumption.
ACEA C3 is similar in its characteristics to C2, but more viscous.
C4 are similar to C1, but more viscous. The content of sulfur, phosphorus elements, ash content of sulfates is minimal.
It should be remembered that the ACEA quality tolerances describe fairly specialized lubricants that are intended for use in certain motors. However, this does not mean that one should ignore the recommendations of the automaker. The manufacturer knows best what kind of petroleum product needs to be poured into his machine.
Class 3
Car oils belonging to this class are marked with the letter E and are poured into highly loaded diesel engines. They cannot be used in petrol / gas engines. In addition to ensuring lubrication of parts, these consumables clean the piston assemblies. Usually they are poured into internal combustion engines certified according to "Euro-1/2/3/4/5". Also, these greases extend drain intervals.
E4 offer the ability to reduce wear on motor parts. The additives they contain help to reduce the formation of soot deposits. In view of this, the motor oil can be used in power units that are not equipped with a soot filter, but are equipped with EGR, SCR. In this case, the lubrication will reduce the concentration of nitrogen oxides in the exhaust gases.
The E6 are similar to the E4, but are intended for use in powertrains that include soot filters.
E7 polish parts for internal combustion engines. They ensure the smoothness of the piston cylinders. Lubricants are poured into engines that are not equipped with soot filters. The presence / absence of ERG / SCR is irrelevant.
E8 is used in powertrains equipped with soot filters. In terms of their characteristics, these oils are close to E7.
Selection of car oil
When choosing a fresh consumable for a car, you must first of all take into account the recommendations of the car manufacturer. Before filling the car with a car oil that differs from the recommended one, be sure to consult with an employee of the service center. Remember that by pouring an unsuitable oil product into the engine, you give the automaker the right to refuse warranty repairs.
In order not to be mistaken with the choice, you need to understand how the oil markings are deciphered. It is not enough to be able to decipher the markings, it is necessary to understand what the characteristics of this or that oil product are. It is possible to get acquainted with the parameters of lubricants by looking at special tables.
The ACEA specification can only be considered as a source of additional information about the type and characteristics of the car oil. This standard is intended to make it easier for drivers to select lubricating fluids. For example, if a lubricant recommended by your car manufacturer is not available in stores, you can choose another one that belongs to the same ACEA class.
ACEA- an 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 merger of CCMC with ATIEL. The CCMC specifications, which have now been superseded by ACEA, classify products as G for gasoline, PD for light and D for heavy diesel engines.
ACEA specifications have been developed to improve quality, productivity and environmental friendliness.
Acceptance of the ACEA specifications implies:
- Commissioning of new innovative materials, in comparison with currently used
- Analysis and certification of quality levels of each formula used
- Manufacturers' commitment not to change approved formulas
- Plant certification ISO 9001/2
- Compliance of manufacturers with ATIEL standards, the organization, together with the CCMC, defined the methods and parameters for the basis of ACEA certificates
The tests required by the ACEA specifications are added to the formulated CCMC and make them more stringent.
The following letters classify the engine types:
[A] - gasoline engines
[B] - light diesel engines
[C] - engines with devices for reducing the amount of exhaust
[E] - heavy diesel engines
The numerical categories indicate the different applications associated with a particular class of motors, indicated by letters. ACEA specifications were last updated in February 2002.
It is the responsibility of the engine manufacturer to select the correct ACEA category.
Oils belonging to a certain category may also meet the requirements of another, but specific engines must be filled with oil of a certain category and class.
The year reference serves only for industrial purposes, giving information about the level and quality of the materials used. More recent revisions of the specifications mean that new tests have been performed or new requirements have been introduced into a category. At the same time, the editions retain backward compatibility, the new ones will always fully support the level of the old ones, except for the cases when a new category is introduced.

The choice of oil for your car has always been important for car enthusiasts and iron horse owners who are not indifferent to their cars.
In particular, many copies have been broken about the interchangeability of oils of ILSAC and ACEA standards, the applicability of low-viscosity oils in modern engines and engines of previous generations, the danger of using such oils under severe operating conditions and forced driving modes. All this can be found and read on the Internet.
We would like, in turn, to bring to the attention of motorists several low-viscosity full ash motor oils from the line of fully synthetic EUROL motor oils of ACEA A5 / B5 standard.
A few words about the ACEA A5 / B5 standard:
This standard was created Association des Constracteuis Europeen des Automobiles (ACEA), the Association of European Automotive Engineers - Europe's largest organization of the largest and most reputable car manufacturers in Europe. The oil performance requirements of this association are more stringent than other ILSAC and API standards.
Oils of category A5 / B5 are classified as full ash, with sulphated ash content up to 1.6% by mass, with volatility up to 13% by mass, with unregulated sulfur and phosphorus content. Ax / Bx categories were created for use in internal combustion engines with external injection (injection into the intake manifold) on fuel with a high sulfur content (over 350mg / kg). These oils should have a high base number of 9-12.
Categories A1 / B1 and A5 / B5 are low-viscosity and are designed to improve the fuel efficiency of internal combustion engines and, as a result, reduce emissions of toxic components and CO2, ensure extended drain intervals and emission standards EURO - 4 and higher. These oils are designed for European high-speed and high-load / forced gasoline and light-duty diesel internal combustion engines with an extended drain interval.
Such an important parameter as HTHS (HighTemperature High Shear) This is the so-called high-temperature viscosity, which indicates the ability of an oil film on friction surfaces to resist rupture under mechanical stress and at high temperatures: for oils of A5 / B5 standard it lies in the range of 2.9 - 3.5 mPa * s. It should be noted that engine wear begins when this parameter is below 2.6 mPa * s.
In the EUROL product line, offered by the official distributor of the brand in Russia, there are three brands of oil corresponding to the ACEA A5 / B5 category: Eurol Fluence FE 5W-30, Eurol Ultrance VA 0W-30, Eurol Fortence 5W-30.
Eurol Fluence FE 5W-30- midSAPS low ash content (0.8), hydrocracked VHVI, base number 7.7, complies with API SN, Renault RN 0700, Peugeot / Citroen PSA B71 2290 approvals.
Eurol Ultrance VA 0W-30- full ash (1.1), low viscosity, hydrocracked VHVI, base number 9, complies with API SL / CF, Volvo VCC 95200377 approval.
Eurol Fortence 5W-30- full ash (1.13), low viscosity, hydrocracking VHVI, base number 9.93, complies with API SL / CF, WSS-M2C-913D (Approved), Ford WSS-M2C-913 A / B / C & 912A, Renault RN 0700.
These oils are suitable for European cars FORD, Volvo, Renault, Peugeot, Citroen, etc. both with modern engines and with engines of previous generations requiring oils of category ACEA A5 / B5, A1 / B1.
If we compare oils of ACEA A5 / B5 and ILSAC GF-5 standards, then it can be noted that these oils are in many respects similar in parameters. But there are differences, such as ash content. ILSAC GF-5 has higher ash content requirements - no more than 1. Moreover, engines of Asian manufacturers can also use hollow ash oils. So why not add A5 / B5 oil to your Toyota or KIA? Can! And many are pouring and are quite happy with the results. But it is important to understand that this oil contains more sulfur and phosphorus in the form of additives and is more prone to deposit deposits in the engine and damage converters. You should not "run over" on this oil more than 10,000 km. and shorten the replacement interval if you like to “crush the sneaker” or have to make short trips in winter with long warm-ups.
Another important point regarding low-viscosity oils: there is an opinion that the lower the viscosity, the easier it is for the motor to spin. A dangerous delusion! Today, engines are specially developed for low-viscosity oils that save fuel and protect the environment. In your Ford or Renault, these oils may simply not work. The low HTHS of modern low viscosity oils, especially with aggressive driving style, can lead to rapid engine wear.
All in all, if you want to save some fuel and extend your oil change intervals, these oils are for you. But before making a purchase decision, be sure to check the instructions for manufacturer's approval of the use of ACEA category A5 / B5 oils.
