Document Type and Number:
WIPO Patent Application WO/2014/017556
Kind Code:
A1
Abstract:
A lubricating oil composition containing: a lubricating oil base oil of which the kinematic viscosity at 100° C is 1-10mm2/s; and a branched poly (meth) acrylate viscosity index improver of which the ratio of a structural unit represented by general formula (1) is 30-90 Mol%, and the degree of branching is 0.1-8.0. [In formula (1), R1 represents hydrogen or a methyl group, and R2 represents a straight-chain or branched hydrocarbon group having a carbon number of 6 or less.]
