International standards, compliance with which is stated in the characteristics of this brand of oil. In modern brands of oil, the following options may be found:
— API — a standard developed in the USA by the American Petroleum Institute. It provides for two separate classifications — for gasoline (
API SG,
SH,
SJ,
SL,
SM,
SN,
SN RC,
SN Plus,
SN Plus RC,
SP,
SP RC,
SP Plus) and for diesel engines (
API CI-4,
CH-4,
CG-4,
CF,
CE,
CD); in the first case, the letter S comes first in the standard designation (for example, API SL), in the second case, C (for example, API CI-4). If the oil is suitable for both types of engines, a double designation is used — for example, API SL/CI-4; in this case, the index of the type for which the oil is best suited comes first (in our example, it is gasoline). The standard also includes a classification of two-stroke engines — TA, TB
..., TC, TC+, TD.
— ACEA — a standard used by the eponymous association of European automakers, an alternative to the American API. Includes three classes: A/B — all oils developed before 2004 for different types of engines. Actually, before 2004 there were two classes — A for gasoline engines and B for diesel engines; then they were combined ( A1/B1, A3/B3, A3/B4 and A5/B5). However, separate designations can still be used. C — oils for all types of engines that meet the Euro-4 environmental standard and are compatible with additional equipment such as catalytic converters and particulate filters. There are APEA C1, C2, C3, C4 and C5. E — a separate class for diesel engines of heavy equipment, including special ones. It has the marking APEA E4, E6, E7 and E9.
— JASO — developed by the Japanese Association of Automobile Standards. It is one of the main modern standards for oils for gasoline motorcycle engines, within this purpose it has two classes — F for two-stroke engines, namely FA, FB, FC, FD and M for four-stroke (subclass MA for wet clutch MA-1 and MA-2, MB for dry). And also a new GLV-1 approval for ultra-efficient gasoline engines and hybrid power plants.
— ILSAC is a standard created jointly by the American and Japanese Automobile Manufacturers Associations. It is used for oils designed for passenger cars with gasoline engines. There are only five ILSAC categories ( GF-2, GF-3, GF-4, GF-5, GF-6A), in general they are similar to certain API categories (see above), but differ in increased requirements for energy saving and limiting harmful emissions.
The list of specific oil standards recommended by the manufacturer for a particular engine is usually specified in the official specifications of the vehicle. Note that many standards are interchangeable; compatibility data (as well as a description of each individual category) can be found in specialized sources.An engine oil quality standard that VAG considers essential for correct operation when used in the engine of its vehicles.
