Abstract

See full text

The present invention relates to a lubricating oil composition containing a base oil (A) containing an olefin-based polymer (A1) having an area ratio of a peak derived from a hydride (A11) of a decene trimer of 80% or more relative to 100% of a total area of peaks derived from the olefin-based polymer (A1) detected in a chromatogram and having predetermined kinematic viscosity, flash point, and pour point, a viscosity index improver (B) containing a comb-shaped polymer (B1), and an organic molybdenum-based compound (C), in which the content of the comb-shaped polymer (B1) is regulated within a specified range and having a HTHS viscosity at each of 150° C. and 50° C. of the lubricating oil composition and a NOACK value in predetermined ranges, respectively.
