In one embodiment a novel lubricant is disclosed. The lubricant comprises an alkylated naphthalene base stock with a viscosity of at least 2 cSt and less than 22 cSt kv100° C., the alkylated naphthalene base stock is greater than 55 weight percent of the lubricant, a PAO base stock with at least 4 cSt and less than 250 cSt kv100° C., the PAO base stock is at least 2 and less than 40 weight percent of the lubricant, at least 0.5 and less than 1.5 weight percent of the lubricant is an amine antioxidant additive, at least 0.5 and less than 1.5 weight percent of the lubricant is a defoamant additive, at least 0.1 and less than 0.4 weight percent of the lubricant is an alkylated rust inhibitor additive, and the lubricant has a viscosity of at least 4 cSt and less than 10 cSt kv100° C., less than 10 ppm metals, less than 100 ppm sulfur, and a VI greater than 70. |
