Patent ID: 8569216

Claim:
A lubricating composition comprising in admixture: from 15 wt. % to 25 wt. % of a Group V base oil component, based on the total weight of the blend components that are used to produce the lubricating composition, wherein the Group V base oil component is alkylated naphthalene, from 65 wt. % to 85 wt. % of a Group IV base oil component, based on the total weight of the blend components that are used to produce the lubricating composition, wherein the Group IV base oil component is one or more polyalphaolefin base stocks, from 0.25 wt. % to 1.5 wt. % of a trithiophosphate-containing compound, based on the total weight of the blend components that are used to produce the lubricating composition, wherein the trithiophosphate-containing compound is S,S,S-Tris-carbo-2-isooctyloxy-methyl trithiophosphate, from 0.25 wt. % to 1.5 wt. % of alkylated diphenyl amine, based on the total weight of the blend components that are used to produce the lubricating composition, and not greater than 5 wt. % of a Group I, Group II, or Group III base oil component, based on the total weight of the blend components that are used to produce the lubricating composition, and wherein the 210 hour oxidation stability test of the lubricating composition yields a value greater than 210 hours.
