Engine oils

The viscosity of the motor oil

For modern engines use only oil HD. Oils HD are oils with high lubricity, enhanced by various additives. These additives provide the best anticorrosive protection, more favorable conditions against the effects of oxidation, the lowest tendency to form slag, the best change in viscosity, clearing and dissolving properties. Cleansing and solubilizing additives not only reduce the formation of residues in the engine, but at the same time are capable of all these residues and other contaminants in the engine oil to dissolve and keep in suspension so that the replacement of oil these contaminants are removed with the oil overflows.
The quality of oil is determined by the HD system API (American Petroleum Institut). European manufacturers also adhere to this system.

Designation grade oil is made by two letters. The first letter describes the field of application: S - Service, designed for gasoline engines; C - Commercial, intended for diesel engines.

The second letter defines an oil grade in alphabetic order.

Oil of the highest grade of API classification are SG for carburettor engines and CD for diesel engines.

Gasoline engines

And - all-weather oils with the raised antifrictional properties, specification VW 500 00.

In - all-weather oils, specification VW 501 01; all-weather oils, specifications API-SF or SG.

Diesel engines

And - all-weather oils with the raised antifrictional properties, specification VW 500 00 (for diesel engines with a turbo-supercharging only in a mix with specification VW 505 00).

In - all-weather oils, specification VW 505 00 (unlimited for all diesel engines), all-weather oils, specifications API-CD (for diesel engines with turbo charging only when absolutely necessary for topping), all-weather oils, specification VW 501 01 (for diesel engines turbo only in mixtures with specification VW 505 00).
