FIELD: chemistry.
SUBSTANCE: described is lubricating oil composition which contains lubricating base oil which contains (A) a partial ester of a polyatomic alcohol and carboxylic acid in amount of 5-75 wt % per total weight of the base oil, and having kinematic viscosity at temperature of 100°C of 1-15 mm2/s. The composition has kinematic viscosity at temperature of 100°C of 1-20 mm2/s, the polyatomic alcohol is an alcohol from a diatomic alcohol to a hexatomic alcohol and the carboxylic acid is selected from a group comprising monobasic acids, polybasic acids and mixtures thereof.
EFFECT: reduced friction between components, which enables to save energy, high efficiency of the lubricating oil composition.
