International Classification:

C10M 107/02

Abstract:

This disclosure provides a method for improving wear control, while maintaining or improving energy efficiency, in a mechanical component having sliding or rolling between contacting surfaces. The method involves using a lubricant composition in the mechanical component having sliding or rolling between contacting surfaces. The lubricant composition has a base stock blend as a major component, and at least one lubricant additive, as a minor component. The base stock blend has at least one first base stock having a viscosity from 1 to 50 cSt at 40 C. and at least one second base stock having viscosity from 100 to 2000 cSt at 40 C. The first base stock is present in an amount greater than 50 to 95 wt % of the base stock blend, and the second base stock is present in an amount from 5 to less than 50 wt % of the base stock blend.
