Patent ID: 8772210

Claim:
A grease with favorable frictional properties, comprising a) a first base stock comprising a PAO with a viscosity of about 150 cSt KV 100° C. and a viscosity index over 100; b) a second base stock with a viscosity of about 50 cSt KV 100° C. less than the viscosity of the first base stock, the second base stock is a PAO, and c) a polyurea thickener, d) an additive package comprising a combination of friction reducers, antiwear additives, extreme pressure additives and rust inhibitors at about 6.8 weight percent of the grease, wherein the first base stock comprises about 83 weight percent of the total base stock, the second base stock comprises about 17 weight percent of the total base stock, the total base stock comprises about 74 weight percent of the grease and the polyurea thickener comprises about 19.1 weight percent of the grease, and wherein the coefficient of friction of the grease as measured by the Optimol SRV test is less than or equal to 0.067 over a load range of from 50 to 600 Newtons.
