Lubricant and functional fluid additive package, and lubricants and functional fluids containing same

A lubricant or functional fluid composition of a lubricating viscosity, comprising:

• a polyalphaolefin having a viscosity of about 10 centiStokes at 100° C. and present in the lubricant or functional fluid composition in an amount of 85.8 percent by weight;
• a polyalphaolefin having a viscosity of about 40 centiStokes at 100° C. and present in the lubricant or functional fluid composition in an amount of 12 percent by weight;
• an anti-wear component consisting essentially of 95% isopropylated triarylphosphate and 5% dodecyl phosphate, the dodecyl phosphate being only partially esterified, the anti-wear component present in the polyolefin oil blend in an amount of 1 percent by weight, the anti-wear component characterized by an acid value from about 10 mg KOH/g to about 15 mg KOH/g;
• an antioxidant component selected from the group consisting of alkylated phenyl-alpha-naphthylamine, phenyl-alpha-naphthylamine and mixtures thereof, the antioxidant being present in the polyolefin oil blend in an amount of 1 percent by weight;
• an anti-rust component comprising an alkenyl succinic acid ester anti-rust agent, the anti-rust component being present in the polyolefin oil blend in an amount of about 0.1 percent by weight;
• a metal deactivator component comprising a tolytriazole derivative, the metal deactivator component being present in the polyolefin oil blend in an amount of 0.1 percent by weight;
• a dye present in the polyolefin oil blend in an amount of 0.01 percent by weight;
• and
• a polydimethlysiloxane present in the polyolefin oil blend in an amount of 0.002 percent by weight,
• the lubricant or functional fluid composition being characterized by a Wedeven Associates Machine (WAM) load stage failure test rating of about the same or greater compared to a WAM load stage failure test rating of 2190-TEP under the same test conditions.

A lubricant or functional fluid composition of a lubricating viscosity and comprising:
