GENERAL INFORMATION

Viscosity of engine oils

For modern engines it is necessary to use only HD oils. HD oils are oils with the increased lubricant properties improved at the expense of various additives. These additives provide the best anticorrosive protection, more favorable conditions against the oxidation phenomenon, the smallest tendency to formation of the slags, the best change of the viscosity, clearing and dissolving properties. Clearing and dissolving additives not only reduce formation of the remains in the engine, but also ability these remains and all other pollution in engine oil at the same time possess to dissolve and keep in a suspension so that at oil replacement these pollution are removed together with merged oil.
Quality of HD oils is determined by API system (American Petroleum Institut). The European producers also adhere to this system.

Designation of a grade of oil is made by two letters. The first letter characterizes a scope: S-Service, are intended for carburetor engines; With – Commercial, are intended for diesel engines.

The second letter defines an oil grade in alphabetical order.

Premium oils on classification of API are SG for carburetor engines and CD for diesel engines.

Petrol engines

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

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

Diesel engines

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

In – all-weather oils, the VW 505 00 specification (it is unlimited for all diesel engines), all-weather oils, the API-CD specification (for diesel engines with a turbo-supercharging only in urgent cases for a dolivka), all-weather oils, the VW 501 01 specification (for diesel engines with a turbo-supercharging only in a mix with the VW 505 00 specification).
