Abstract
A lubricating oil composition comprising a base oil, a zinc dialkyldithiophosphate, and a sarcosine derivate is described. The lubricating oil composition may comprise the zinc dialkyldithiophosphate at a concentration of 0.10 to 10 mass % and the sarcosine derivate at a concentration of 0.01 to 5.0 mass %. The lubricating oil composition may have a kinematic viscosity at 100° C. of 6.5 mm/s or less, and can be used for lubricating a speed reducer.
