Abstract (en)

A lubricating oil composition is used in an internal combustion engine that uses a fuel containing at least one fat and oil selected from a group consisting of natural fat and oil, hydrotreated natural fat and oil, transesterified natural fat and oil and hydrotreated transesterified natural fat and oil. 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.
