Abstract:
1. A lubricating oil formulation prepared from a blend of components comprised of: from 19.7 wt % to 78.7 wt % of a metallocene catalyzed PAO having a viscosity of at least 135 cSt, Kv 100° C. and a CH from 11 wt % to 70 wt % of a PAO having a viscosity of not greater than 40 cSt, Kv 100° C., based on total weight of the blend components of the formulation; and from 10.3 wt % to 13.3 wt % of a combination of at least one Group V basestock selected from the group consisting of alkylnaphthalenes, alkylbenzenes, polyalkylene glycols and esters and a gear oil additive pack, based on total weight of the blend components of the formulation; wherein the sum of the metallocene catalyzed PAO having a viscosity of at least 135 cSt, the PAO having a viscosity of not greater than 40 cSt, and the combination of at least one Group V basestock and a gear oil additive pack is about 100 wt %; wherein the lubrication oil formulation exhibits an air release time to 0.2% air of not greater than 7.1 minutes, according to ASTM D3427-03 at 75° C.
