System of greasing of the engineEngine greasing is carried out by all-weather oil that excludes necessity of replacement of oil at change of a season (summer/winter). A basis of this oil is маловязкое seasonal oil (for example, 10 W) which in a hot condition becomes more viscous by means of so-called “the viscosity stabilizer”. Thereby, effective greasing, both cold, and the hot engine is provided.
(Oils easy oils can be applied to high capacities) also. They represent all-weather oils into which as an additive along with others are entered уменьшители friction factor. In easy oils as a basis so-called synthetic oils are applied.
Scope viscosity oils/classes
Designation SAE specifies in viscosity of impellent oil.
For example: SAE 10 W 40:
10 viscosity of oil in a cold condition. Than number, especially liquid oil in a cold condition less.
W oil is suitable for application in the winter
40 viscosity of oil in a hot condition. Than number, especially dense oil in a hot condition more.

Спецификациия impellent oil
The European manufacturers classify the oils under the specification “ACEA” (Association des Constucteurs Europeens de I‘Automobile) which considers, first of all, the European "know-how" of engines. Oils for petrol engines of cars have under specification ACEA classes of quality with А1-96 on А3-96, oils of diesel engines have classes with В1-96 on В3-96. Oils А3 for petrol and В3 for diesel engines have the highest quality.
Classification of impellent oils by the American manufacturers is carried out on system API (API: American Petroleum Institut). The designation consists of two letters. The first letter specifies in a scope: S - Service, it is intended for petrol engines; C - Commercial, it is intended for diesel engines. The second letter specifies in quality in alphabetic order. Oils of API-specification SJ for petrol and CF for diesel engines have the first-rate quality.
Firm BMW for the engines has established other norms and impellent oils classifies as “Longlife-le” and “Spezialle”.
