    摘要: The present invention provides a lubricating oil composition for an internal combustion engine used mainly to drive a generator and to improve the fuel economy thereof. The composition comprises (A) a base oil being a hydrocarbon base oil having a ratio (CA/CB) of the proportion of the component of 24 or fewer carbon atoms (CA) and the proportion of the component of 25 or more carbon atoms (CB) in the carbon number distribution obtained by gas chromatography distillation of 2.0 or higher, the composition having a ratio (Vs/Vk) of the 80° C. high-temperature high-shear (HTHS) viscosity (Vk) and the 150° C. HTHS viscosity (Vs) of 0.35 or higher and a 100° C. kinematic viscosity of 2.5 mm2/s or higher and 5.2 mm2/s or lower.
