PROBLEM TO BE SOLVED: To provide a lubricating oil composition that has a low friction coefficient (traction coefficient), excellent low-temperature flowability and is suitable as a transmission oil for automatic transmissions, etc.SOLUTION: A lubricating oil composition uses a base oil containing a high-viscosity index mineral oil satisfying the following conditions of (1) a kinematic viscosity at 100°C of 5-8 mm/s, (2) a viscosity index of ≥130 and (3) a (%Cof ≥80 by ring analysis (n-d-M method). |
