(57) [Summary] [Object] To provide a lubricating oil composition having a low coefficient of friction and improved copper corrosion. Also, to provide a lubricating oil composition that exhibits a low friction coefficient from the initial stage and has improved copper corrosiveness. [Composition] (a) 0.01% by weight or more and less than 0.2% by weight of sulfurized oxymolybdenum dithiocarbamate and / or sulfurized oxymolybdenum organophosphorodithioate in mineral oil, and (b) zinc dithiophosphate and / or A lubricating oil composition comprising zinc dithiocarbamate in an amount of 0.5 to 7% by weight. A lubricating oil composition further comprising (c) an organic amide compound in a proportion of 0.01 to 5% by weight. |
