PURPOSE:To provide the subject composition having a low abrasion coefficient and excellent in the abrasion resistance by adding a sulfideoxymolybdenum dithiocarbamate, etc., to a lubricant base oil in a specific ratio. CONSTITUTION:A lubricant base oil is compounded with (A) 0.01-10wt.% of sulfideoxymolybdehum dithiocarbamate and sulfideoxymolybdenum organophosphodithioate, (B) 0.01-10wt.% of a fatty acid ester and/or an organic amide compound, (C) 0.1-10wt.% of one kind or more of compounds selected from calcium sulfonate, magnesium sulfonate, calcium phenate or magnesium phenate, (D) 0.5-15wt.% of one kind or more of compounds selected from benzylamine, the boric acid derivative of benzylamine, an alkenylsuccinic acid imide and the boric acid derivative of the alkenylsuccinic acid imide, and (E) 0.1-7wt.% of one kind or more of organic zinc compounds selected from zinc dithiophosphate and zinc dithiocarbamate. |
