Title: LUBRICATING OIL COMPOSITION, METHOD FOR MANUFACTURING LUBRICATING OIL COMPOSITION, AND DRIVE SYSTEM APPARATUS
Abstract:
Provided is a lubricating oil composition comprising: a base oil having a kinematic viscosity at 40°C of 4.0 mm2/s or more and less than 6.0 mm2/s, a kinematic viscosity at 100°C of 1.0 mm2/s or more and less than 2.0 mm2/s, and a flash point of 140°C or higher; and a viscosity index improver. The lubricating oil composition has a Brookfield viscosity at -40°C of 750 mPa∙s or less, a kinematic viscosity at 60°C of 5.5 mm2/s or more, and a NOACK value at 145°C for an hour of 10 mass% or less, has excellent viscometric properties, and does not tend to evaporate.
