System of greasing of the engineGreasing of the engine is carried out by all-weather oil that excludes need of replacement of oil at season change (summer/winter). A basis of this oil is low-viscous 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.
Also light oils (oils can be applied to high capacities). They represent all-weather oils into which as an additive along with others umenshitel of factor of a friction are entered. In light oils as a basis so-called synthetic oils are applied.
Scope viscosity oils/classes
Designation of SAE indicates 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.

Spetsifikatsiiya of impellent oil
The European manufacturers classify the oils according to the ACEA specification (Association des Constucteurs Europeens de I‘Automobile) which considers, first of all, the European production technology of engines. Oils for petrol engines of cars have according to the ACEA specification quality classes with A1-96 on A3-96, oils of diesel engines have classes with B1-96 on B3-96. A3 oils for petrol and В3 for diesel engines have the highest quality.
Classification of impellent oils by the American manufacturers is carried out on API system (to API: American Petroleum Institut). Designation consists of two letters. The first letter indicates a scope: S-Service, is intended for petrol engines; C-Commercial, is intended for diesel engines. The second letter indicates quality in alphabetical order. SJ API specification oils for petrol and CF for diesel engines have the first-rate quality.
The BMW firm for the engines established other norms and impellent oils classifies as “Longlife-Öle” and “Spezialöle”.
