| titleOfInvention | Lubricating oil composition |
| abstract | 【Task】 The present invention provides a lubricating oil composition having a relatively high viscosity at a high temperature (for example, 100 ° C. or higher) and a low shear viscosity at a shear rate (× 107 / s) at 100 ° C. The purpose. SOLUTION: A lubricating oil composition containing (A) a base oil and (B) (co) polymer and having a NOACK evaporation amount of 25% by mass or more and less than 40% by mass, wherein the (A) base oil operates at 100 ° C. The component (B) having a viscosity of 2.5 to 3.5 mm 2 / s and a weight average molecular weight (Mw) of 100,000 to 1,000,000 is 1.0 to 10 mass with respect to the total mass of the lubricating oil composition. %, The kinematic viscosity at 100 ° C is 5.0 or more and less than 9.3 mm 2 / s, the high temperature and high shear viscosity at 100 ° C ( 107 / s) is 3.0 or more and less than 4.5 mPa · s, and 100 ° C. Ratio of high-temperature high-shear viscosity ( 107 / s) at 100 ° C to high-temperature high-shear viscosity (10 6 / s) at 100 ° C [(high-temperature high-shear viscosity at 100 ° C (10 7 / s)) / (100) The lubricating oil composition, wherein the high-temperature and high-shear viscosity at ° C. ( 106 / s))] is 0.70 or more and less than 0.99. [Selection diagram] None |
