PROBLEM TO BE SOLVED: To obtain an oil composition which can prevent scratching in an automotive AT belt type CVT by mixing a base oil with a plurality of specified substances. SOLUTION: This composition is obtained by mixing a base oil (e.g. paraffinic mineral oil) desirably containing a viscosity improver with a sulfonate (e.g. calcium sulfonate), an ashless dispersant desirably being an imide compound (e.g. alkylsuccinimide), an acid amide (e.g. an amide of a fatty acid with a polyalkylenepolyamine), an organomolybdenum compound desirably being molybdenum dithiophosphate or molydenum dithiocarbamate, and an amine antioxidant (e.g. alkylate of diphenylamine). |
