Abstract
An object of the present invention is to provide a lubricating oil composition particularly excellent in viscosity characteristics at a low temperature. The present invention provides: a lubricating oil composition including a polymer (A) and a base oil (B), wherein the polymer (A) satisfies the following requirement (A-1), and the content ratio of the polymer (A) and the base oil (B) is such that the ratio of a resin (A) is within the range of from 0.1 to 50 parts by mass with respect to 100 parts by mass of the total amount of the polymer (A) and the base oil (B). (A-1) The polymer (A) is a polymer containing a structural unit derived from an α-olefin having 20 or less carbon atoms.
