Abstract (en)
A lubricating oil composition contains: a first base oil with a kinematic viscosity at 100 degrees C in a range from 1.5 mm 2 /s to 3.5 mm 2 /s; a second base oil with a kinematic viscosity at 100 degrees C in a range more than 3.5 mm 2 /s but not more than 100 mm 2 /s; polymethacrylate with a mass average molecular weight in a range from 1 × 10 4 to 4 × 10 4 ; and a sulfur compound. The lubricating oil composition has a kinematic viscosity at 100 degrees C in a range from 5 mm 2 /s to 6 mm 2 /s and a viscosity index of 200 or more.
