Patent abstract
A lubricating oil composition of the invention includes a lubricant base oil of which kinematic viscosity at 100 degrees C. is 1 to 5 mm2/s; and at least one component selected from an olefin copolymer (OCP) and a poly-α-olefin (PAO) of which kinematic viscosity at 100° C. is 20 to 2000 mm2/s, a kinematic viscosity of the lubricating oil composition at 100 degrees C. being 8 mm2/s or less and viscosity index thereof being 155 or more.
