LUBRICATING OIL COMPOSITIONS

摘要

A lubricating oil composition for use in wet brakes comprising a base oil selected from mineral oils and synthetic oils and mixtures thereof, and from 0.01 to 0.5% by mass, relative to the lubricating oil composition, of a diol compound (A) represented by Formula (1), CnH2n+2O2 or CnH2nO2 (Formula 1), wherein the number of carbon atoms n is in the range of from 10 to 24. The lubricating oil compositions of the present invention have excellent wet brake friction characteristics and wear resistance as well as oxidative stability and are suitable as a general-purpose lubricating oil for agricultural tractors or construction machinery vehicles.
