LUBRICATING OIL COMPOSITION

摘要

A lubricating oil composition comprising a base oil having a kinematic viscosity at 40 ºC in the range of from 2 to 20 mm<SUP>2</SUP>/s and a viscosity index of 50 or more and a polymethacrylate, wherein the lubricating oil composition has a kinematic viscosity at 40 ºC in the range of from 22 to 95 mm2/s; a kinematic viscosity at 100 ºC in the range of from 10 to 30 mm<SUP>2</SUP>/s; a pour point of -10 ºC or less; a CCS viscosity at -20 ºC of 2500 mPas or less; and a flash point of 140 ºC or more.
