LUBRICATING OIL COMPOSITION

摘要

Provided is a lubricating oil composition with a low coefficient of friction (coefficient of traction) and excellent low-temperature fluidity, wherein the lubricating oil composition is made suitable as a transmission oil for an automatic transmission by using a base oil containing a mineral oil that satisfies the following conditions: (1) the kinematic viscosity at 100°C is 5 to 8 mm2/s; (2) the viscosity index is 130 or higher; (3) the %Cp derived by ring analysis (n-d-M) is 80 or higher.
