Abstract (en)

[origin: EP3249030A1] A lubricating oil composition according to one embodiment of the present invention contains an oxygen-containing synthetic base oil having an oxygen content (A) of from 15 to 40 mass% and a kinetic viscosity at 100°C of from 0.5 to 50 mm 2 /s, and a viscosity index improver that is an oxygen-containing compound having an oxygen content (B) of from 15 to 40 mass% and a kinetic viscosity at 100°C of 11,000 mm 2 /s or more, a mass ratio of the oxygen-containing synthetic base oil and the viscosity index improver being from 99.5:0.5 to 75:25, and a ratio (A/B) of the oxygen content (A) of the oxygen-containing synthetic base oil to the oxygen content (B) of the viscosity index improver being in a range of from 0.5 to 2.
