All-weather oils on the VW 501 01 standards and 505 00 are rather inexpensive oils with the following qualities:
– all-the-year-round use in zones of a temperate climate;
– excellent washing properties;
– good greasing ability at all temperatures and engine loadings;
– high stability of initial properties for a long time.
All-weather oils with the improved antifrictional qualities on the VW 500 00 standard have, besides, additional advantages:
– all-the-year-round use honor at all possible temperatures of external air;
– small losses of engine capacity on a friction;
– simplification of cold start-up of the engine – as well at very low temperatures.
Prevention
Seasonal oils owing to specific vyazkostno-temperature properties inherent in them usually cannot be used all the year round. Therefore these oils should be applied only in extreme climatic zones.
When using all-weather oils of the class SAE 5W-30 it is necessary to avoid long operation of the engine with high frequency of rotation and constant big load of the engine. These restrictions are not valid for all-weather oils with the improved antifrictional qualities.
It is not necessary to add any additives reducing losses on a friction, to engine oils.
