FIELD: chemistry.

SUBSTANCE: composition based on mineral, synthetic, or semi-synthetic motor oil with an alkyl additive (C₆-C₁₂) of lactic acid ester (alkyl lactate), the molybdenum complex of dioximolybdenum (VI) with benzoylhydrazone of 2-hydroxy-1-naphthaldehyde (molybdenum complex) and organic compounds, contains synthetic oil based on pentaerythritol ether and fatty (C₆-C₁₀) of acids (ester-2), for example B-3B (synthetic oil) as the organic compounds, and additionally polyethylsilicone, as well as 2-hydroxynaphthyl dodecylimine. Herewith the components of the additive are taken in the ratio, wt %: 2-hydroxynaphthyl dodecylimine 0.1-1; complex of molybdenum 0.1-2; alkyl lactate 10-50; synthetic oil 20-80; polyethyl siloxane 7-50. The amount of the additive in the composition is 1-15%.

EFFECT: increasing the antifriction and load characteristics of lubricant compositions based on mineral, synthetic, or semi-synthetic motor oils.
