Abstract
A lubricant formulation and method of blending a lubricant formulation is disclosed. The lubricant formulation comprises at least two base stocks. The first base stock comprises a viscosity greater than 40 cSt, Kv100° C. and a tight molecular weight distribution as a function of viscosity. The second base stock comprises a viscosity less than 10 cSt, Kv100° C. The lubricant formulation provides favorable properties.
