Abstract
Provided is a lubricating oil composition for a two-wheeled vehicle, containing a base oil, (A) a zinc dialkyldithiophosphate, and (B) a molybdenum-based friction modifier, in which a mass ratio (P/Mo) of a content of a phosphorus atom derived from the zinc dialkyldithiophosphate (A) to a content of a molybdenum atom derived from the molybdenum-based friction modifier (B) is 0.8 or more and less than 2.0, and a kinematic viscosity at 100° C. is 5.0 to 7.1 mm2/s, the lubricating oil composition for a two-wheeled vehicle by which excellent fuel efficiency is achieved.

A lubricating oil composition for a two-wheeled vehicle, comprising:
- a base oil;
- a zinc dialkyldithiophosphate;
- and
- a molybdenum-based friction modifier,
- wherein a mass ratio of a content of a phosphorus atom derived from the zinc dialkyldithiophosphate to a content of a molybdenum atom derived from the molybdenum-based friction modifier is 0.8 or more and less than 2.0, and a kinematic viscosity of the lubricating oil composition at 100° C. is in a range of 5.0 to 7.1 mm2/s.
