LUBRICANT COMPOSITION

摘要

A lubricating oil composition of the invention includes a lubricant base oil of which kinematic viscosity at 100 degrees C is 1 to 5 mm 2 /s; and at least one component selected from an olefin copolymer (OCP) and a poly-±-olefin (PAO) of which kinematic viscosity at 100°C is 20 to 2000 mm 2 /s, a kinematic viscosity of the lubricating oil composition at 100 degrees C being 8 mm 2 /s or less and viscosity index thereof being 155 or more.
