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 300 cSt, Kv100° C. and a tight molecular weight distribution as a function of viscosity. The second base stock comprises a viscosity less than 100 cSt, Kv100° C. The lubricant formulation provides favorable properties.

Abstract: A premium wear resistant lubricant comprises a base stock, preferably a GTL liquid or the liquid isomerization product of slack wax or F-T wax, and a non-ionic ashless anti-wear additive. The non-ionic ashless antiwear additive is preferably at least one of thiosalicylic acid or alkyl ester thereof, thioxomalonate, 2,2-dithiopyridine and thiazolidine. The lubricant may also contain additional base stock materials selected from other hydrocarbonaceous and synthetic base stock materials in admixture with the GTL liquid or slack wax or F-T derived base stock.
