Lubricant additive compositions having improved viscosity index increasing properties |
| abstract |
A lubricant composition, additive concentrate, and method for lubricating an engine. The crankcase lubricant has less than 30 weight percent of a relatively low Noack volatility base oil and a viscosity additive. The viscosity additive has a minor effective amount of sacrificial polymeric viscosity index improver having a shear stability index (SSI) of greater than about 45 and a major amount of aviscosity index improver having an SSI of less than about 26. The minor amount of sacrificial viscosity index improver additive is effective to provide a lubricant composition having a ratio of absolute viscosity increase at 40 DEG C. to an absolute viscosity increase at 40 DEG C. of an RL 216 reference oil of less than about 0.8. |
