LUBRICATING OIL COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a new lubricating oil composition containing a metal salt of an organic acid and excellent in the effect of reducing the coefficient of friction. SOLUTION: This composition is obtained by blending a lube base oil with an effective amount of metal salts of an organic acid which comprise a mixture of metal salts of an aromatic organic acid substituted by linear hydrocarbon groups, wherein the aromatic group is substituted by at least one linear hydrocarbon group, and in which the linear hydrocarbon groups having an aromatic group bound to the C at the 2 or 3 position account for 30-90% of the total linear hydrocarbon groups.
