Abstract (en)
A lubricating oil composition contains a base oil containing a compound (A) and a compound (B) below and a compound (C). The lubricating oil composition exhibits a kinematic viscosity at 40 degrees C in a range of 20 mm 2 /s to 40 mm 2 /s, a density at 15 degrees C of 1.1 g/cm 3 or more, a flash point of 200 degrees C or more, and a viscosity index of 100 or more. The compound (A) is an ester or an ether having two or more aromatic rings. The compound (B) is an ester or an ether having a kinematic viscosity at 40 degrees C of 12 mm 2 /s or less, a density at 15 degrees C of 0.9 g/cm 3 or more and a flash point of 100 degrees C or more. The compound (C) is a poly(meth)acrylate having a mass average molecular weight of 50000 or less.
