The applied motive oils. Oil consumption

Greasing of the engine is carried out by all-weather oil that does not demand seasonal change of oil (summer/winter). All-weather oils are based on seasonal oil with low viscosity (for example, 10 W) and are stabilized in a hot state by means of "the viscosity stabilizer". Thanks to it possibility of greasing of both the cold, and hot engine is provided.

Designation on SAE characterizes viscosity of motive oil.

Example: SAE 10 W 40:

10 — Viscosity of oil in a cold state. The number is less, the oil has smaller viscosity.

W — Oil is suitable for operation in the winter.

40 — Viscosity of oil in a hot state. The more hot oil has number, the smaller viscosity.

Motive Longlife oil

Engines of AUDI A4 cars are filled at plant with Longlife special oil. At use of Longlife oil according to norms of VW, the two-year interval of service is provided.

Also usual motive oil according to norms of VW can be applied. But in this case the interval of service has to be reduced till 12 months of/15.000 km.

Types of oils are given in Specifications.

If for filling of the lubrication system there is no Longlife oil, it is possible to fill in 0.5 l of motive oil on norm of VW 502 00 (the petrol engine) or on norm 505 00/505 01 (the diesel engine), without transferring the indicator of terms of service to the situation "nicht flexibel" ("not flexible").

Oil consumption

At internal combustion engines the consumption of oil is understood as its such quantity which is consumed owing to combustion process. It is not necessary to confuse an oil consumption to its loss arising owing to leakage of the pallet of a case, a cover a head of cylinders, etc.

The normal consumption of oil arises owing to combustion of a small amount of oil in cylinders, owing to branch with products of combustion and products of wear. Besides, oil is lost owing to the high temperatures of combustion and a high pressure taking place during the operation of the engine. Also external service conditions have impact on a consumption of oil, such as management style the car, and also admissions of production of details of the engine. The consumption of oil should not exceed 0.8 l / 1000 km.

Do not fill in oil above Max mark at all. If the excess amount of oil was poured, it is necessary to remove it. Otherwise the catalytic converter since not burned down oil gets to system of release can be damaged.
