Abstract:
1. A lubricating oil composition comprising: (A) a base oil with a kinematic viscosity at 100° C. of 1 to 8 mm (B) 0.005 to 0.4 percent by mass of a metallic detergent; (C) 0.005 to 0.2 percent by mass in terms of nitrogen of a succinimide-type ashless dispersant; (D) 0.005 to 0.2 percent by mass in terms of phosphorus of a phosphorus-containing anti-wear agent; and (E) 0.01 to 20 percent by mass of a viscosity index improver with a weight average molecular weight (Mw) of 50,000 or greater; wherein a viscosity index of the composition is 160 or greater.
