LOW VISCOSITY LUBRICANT COMPOSITIONS |
| 摘要 |
Lubricant formulations are provided having a base oil blend, the base oil blend having a first Fischer-Tropsch derived base oil having a kinematic viscosity at 100° C. of between 2.5 and 3.5 cSt and a second Fischer-Tropsch derived base oil having a kinematic viscosity at 100° C. of between 3.5 and 4.5 cSt, wherein the resulting base oil blend has a Noack volatility of less than 15%. The first Fischer-Tropsch derived base oil can be present in an amount up to 12 wt. % and the second Fischer-Tropsch derived base oil can be present in an amount up to 88 wt. %. |
