Abstract (en)

The oil composition for infinite variable speed devices of the present invention comprises: (a) a lubricating oil base oil, (b) a polymethacrylate, (c) a phenate or sulfonate of alkaline earth metal, (d) an imido compound, (e) an (alkyl)phenyl (thio)phosphate, (f) a zinc dithiophosphate, and (g) a fatty acid amide compound. The oil composition exhibits a high coefficient of friction required for transmitting power to large output engines, and excellent capability of preventing abrasion and scratch noises. Therefore, the composition can be suitably used as a lubricating oil for a CVT for vehicles.
