An oil composition for non-stage transmissions which is obtained by incorporating (b) a polymethacrylate, (c) the phenate or a sulfonate of an alkaline earth metal, (d) an imide compound, (e) an (alkyl)phenyl (thio)phosphate, (f) zinc dithiophosphate, and (g) a fatty acid amide compound into (a) a lube base oil. It has such a high coefficient of friction that it can transmit the power of a high-output engine, and is highly effective in wearing prevention and scratch noise prevention. It is hence useful as a lubricating oil for automotive CVTs. |
