Abstract: There is provided a lubricating oil composition containing a base oil (A), a molybdenum-based friction modifier (B), a metal-based detergent (C), and a dispersant (D), in which the dispersant (D) contains a non-boron-modified polyisobutenyl succinic bisimide (D1), in an IR spectrum of the non-boron-modified polyisobutenyl succinic bisimide (D1) as determined by an FT-IR method, a ratio [Abs (1705 cm -1 )/Abs (1390 cm -1 )] of a peak intensity Abs (1705 cm -1 ) at 1705 cm -1 to a peak intensity Abs (1390 cm -1 ) at 1390 cm -1 is 7.5 or less, a content of the non-boron-modified polyisobutenyl succinic bisimide (D1) is 50 mass% or more based on a total amount of the dispersant (D), and a kinematic viscosity at 100°C is 9.3 mm 2 /s or less. The lubricating oil composition has an excellent effect of reducing a friction coefficient while containing a molybdenum-based friction modifier and a succinimide compound.
