A polyol ester having a kinematic viscosity in the range of 3 to 8 mm 2 /s at 100 degrees C and/or a polybasic acid ester having a kinematic viscosity in the range of 3 to 8 mm 2 /s at 100 degrees C is mixed in an amount in the range of 5 to 30 mass% of a total amount of the lubricating oil composition as a base oil of lubricating oil.
