To provide a lubricating oil composition capable of further reducing the lubricating resistance in the same viscosity grade and further improving the energy saving performance of the lubricating oil. A lubricating base oil is blended with a viscosity index improver having a PSSI of 30 or less so that the viscosity index of the composition is 160 or more and the rate of decrease in kinematic viscosity at 100 ° C. after shearing is 15% or less. A lubricating oil composition characterized by comprising: [Selection figure] None |
