Patent ID: 8299007

Claim:
A lubricating oil formulation prepared from a blend of components comprised of: at least 47.10 wt % metallocene catalyzed PAO having a viscosity of greater than or equal to 150 cSt, Kv 100° C., based on total weight of the blend components of the formulation; not greater than 40.00 wt % PAO having viscosity of less than 10 cSt, Kv 100° C., based on total weight of the blend components of the formulation; and at least one cohase stock selected from the group consisting of alkylated naphthalene, alkylated benzene, alkylated diphenyloxide, alkylated diphenylsulfide, alkylated diphenylmethane, mono-basic esters, di-basic esters, and tri-basic esters, wherein the lubricating oil formulation has a viscosity greater than 3.5 cSt, Kv 100° C., and a viscosity index greater than 120, and wherein the lubricating oil formulation exhibits an air release time to 0.2% air of 17 minutes or less, according to ASTM D3427.
