Title:
LUBRICATING OIL COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2016/159006
Kind Code:
A1
Abstract:
This lubricating oil composition contains: a lubricating-oil base oil having a kinematic viscosity of 1-10 mm2/s at 100°C and a %CP of 70 or more; (A) 0.1-30 mass% of a poly(meth)acrylate viscosity index improver having an A/B ratio of less than 2.4, where A represents the thickening effect of the kinematic viscosity at 100°C and B represents the thickening effect of the HTHS viscosity at 150°C, a C/B ratio of less than 1.4, where C represents the thickening effect of the kinematic viscosity at 150°C and B represents the thickening effect of the HTHS viscosity at 150°C, a PSSI of 5 or less, and a weight average molecular weight of 10,000-500,000; and (B) 0.01-2.0 mass% of a friction adjusting agent.
