M-8V

GOST 10541-78

Motor oil M-8B is used all-season in medium-duty gasoline engines of cars and trucks with a frequency of replacement up to 18 thousand km of run, as well as winter oil for medium-engine diesel engines. It is prepared from a mixture of distillate and residual components or a distillate component of a narrow fractional composition with an effective additive composition.
