| description | An object of the present invention is to provide: an additive composition for a lubricating oil that exhibits high friction-reducing effects even under severe conditions in which high contact pressure is applied; and a lubricating oil composition obtained by blending the composition in a base oil. In order to achieve the object, the present invention provides the following lubricant composition and a lubricant oil composition obtained by blending the composition in a base oil. The lubricant composition includes: a molybdenum dithiocarbamate (A) represented by the general formula (1) ; and a copolymer (B) that includes, as essential constitutional units, a unit (a) represented by the general formula (2) and a unit (b) represented by the general formula (3), has a weight-average molecular weight of from 5,000 to 150,000, and has a composition ratio of the unit (a) to the unit (b), i.e., (a)/(b), of from 50/50 to 90/10 by mole. |
