PURPOSE:To obtain the subject lubricant composition reduced in viscosity without causing reduction of abrasion resistance or occurrence of seizing, capable of improving the output of an engine and useful for, e.g. racer oil for a high- power gasoline engine, etc., by blending a traction oil with a lubricant base in a specified ratio. CONSTITUTION:This composition is composed of (A) a lubricant base and (B) 5 to 50wt.% traction oil. Preferably, e.g. a hydrocarbon-based base oil such as a poly-alpha-olefin having 4 to 8 cst dynamic viscocity at 100 deg.C and, e.g. a synthetic naphthalic oil represented by the formula (R1 to R4 each is 1 to 3C hydrocarbon), etc., are used as the component (A) and the component (B) respectively. |
