Abstract (en)
The purpose of the present invention is to provide a lubricating oil composition that can suppress wear of bearings and the like and scoring of gear teeth surfaces and the like even at low viscosity. Provided is a lubricating oil composition that includes a lubricating oil base oil, a sulfur-based extreme pressure agent, and a phosphorus-based extreme pressure agent, wherein the lubricating oil composition is characterized in that: the quantity of active sulfur in the sulfur-based extreme pressure agent is 5-30% by mass; the sulfur-based extreme pressure agent is included in the composition at a quantity of 5-15% by mass relative to the mass of the entire lubricating oil composition; and the phosphorus-based extreme pressure agent is included in the composition at a quantity of 1.5-8% by mass relative to the mass of the entire lubricating oil composition.
