LUBRICATING OIL COMPOSITION

摘要

The present invention is directed to providing a lubricating oil composition which contains an alkyl group asymmetric type molydbdenum dithiocarbamate (MoDTC) as an essential component thereof and which exhibits far more excellent lubrication performance than a conventional lubricating o il composition containing an alkyl group symmetric type MoDTC conventional used in the field of lubricating oils. The lubricating oil composition according to the present invention comprises a base oil for a lubricating oil consisting of a mineral oil and/or a synthetic oil and having a viscosity index of at leas t 115 and a viscosity at 100.degree.C falling within the range of 2 to 50 cSt, and a specific alkyl group asymmetric type MoDTC as an essential component.
