LUBRICANT COMPOSITION AND METHOD FOR PRODUCING SAME |
摘要 |
A lubricating oil composition comprising: a lubricating base oil comprising a first lubricating base oil component having a urea adduct value of not greater than 4% by mass, a kinematic viscosity at 40° C. of 14-25 mm2/s and a viscosity index of 120 or higher and a second lubricating base oil component having a kinematic viscosity at 40° C. of less than 14 mm2/s, wherein the content of the first lubricating base oil component is 10-99% by mass and the content of the second lubricating base oil component is 1-50% by mass, based on the total amount of the lubricating base oil; and a viscosity index improver, the lubricating oil composition having a kinematic viscosity at 100° C. of 4-12 mm2/s and a viscosity index of 200-350.
