  • Publication number: 20240110121
    Abstract: 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). The IR spectrum of the non-boron-modified polyisobutenyl succinic bisimide (D1) is determined by an FT-IR method, having 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 contains a kinematic viscosity at 100° C. is 9.3 mm2/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.
