(57) [Problem] To provide a lubricating oil composition for an internal combustion engine having excellent low-temperature fluidity, excellent fuel economy, and excellent engine durability. (A) A kinematic viscosity at 100 ° C. of 2.5 to 1 to 25% by weight of a lubricating base oil produced by a catalytic dewaxing process at 3.5 mm 2 / s, pour point -30 ° C. or lower, A kinematic viscosity at 00 ° C of 3.5 to 7.0 mm 2 / s, an aromatic content of 0 to 5 wt%, and a lubricating base oil 75 to 99.5 produced by a hydrocracking process with a pour point of -15 ° C or less. For 100 parts by weight of a lubricating base oil consisting of (B) A lubricating oil composition for an internal combustion engine, comprising an oil-soluble organic Mo compound selected from molybdenum dithiocarbamate and molybdenum dithiophosphate in an amount of 300 to 1200 ppm as Mo content. |
