Abstract
A lubricating oil composition useful for internal combustion engines comprises a base oil, and, as combined therewith, specified amounts of a molybdenum dialkyl-dithiocarbamate, a selected zinc dihydrocarbyl dithiophosphate and a selected copper carboxylate, respectively. The oil composition exhibits a high friction-reducing effect when the oil is fresh and maintains the same effect even after the oil has been deteriorated.
