Title:

LUBRICANT COMPOSITION FOR INTERNAL COMBUSTION ENGINES

Document Type and Number:

WIPO Patent Application WO/2012/026399

Kind Code:

A1

Abstract:

This lubricant composition for internal combustion engines is characterized by containing an organic molybdenum compound as a component (A), a base oil having a kinematic viscosity at 100˚C of not less than 25 mm2/second as a component (B), and a base oil having a kinematic viscosity at 100˚C of less than 12.5 mm2/second as a component (C). The lubricant composition for internal combustion engines is also characterized by having a kinematic viscosity at 100˚C of 5-12.5 mm2/second and a phosphorus content of not more than 800 ppm.
