Abstract
A lubricating oil composition for a transmission includes a base oil in a range of 1 mass % to 80 mass %, the base oil having a kinematic viscosity at 40 degrees C. in a range of 0.5 mm/s to 20 mm/s and a viscosity index of 200 or more. Since the composition exhibits a high viscosity index and a high shear stability, the composition is suitable for a continuously variable transmission.
