Abstract

This invention relates to a lubricating oil composition comprising or resulting from the admixing of:

(i) at least 50 mass %, based upon the weight of the lubricating oil composition, of base oil,(ii) at least one capped dispersant having number average molecular weight (Mn) of less than 1600 g/mol,(iii) at least one magnesium containing detergent,(iv) at least one calcium containing detergent,(v) at least one copolymer viscosity modifier that has: 1) a ratio of relative KV140/relative KV20 of 1.9 or more;2) a ratio of relative KV100/relative KV70 or 1.30 or more; and3) a viscosity index (ASTM 2270D) of 320 or more, when 1), 2) and 3) are measured on blend, having a KV100 of about 8 cSt, of the copolymer viscosity modifier and a group III base oil having a KV100 (ASTM D445) of about 4 cSt and a viscosity index (ASTM D2270) of about 120.
