Abstract:
1. An oil formulation comprising: a) a chromium catalyzed HVI-PAO at from 34.9 to 43.9 wt % of the oil formulation with a viscosity of 150 cSt kv 100° C. and a viscosity index greater than 100; b) a second chromium catalyzed low viscosity PAO base stock at from 23 to 28 wt % of the oil formulation with a viscosity of 2 cSt kv 100° C.; c) di-octyl sebacate ester with a viscosity of at least 2 and less than 6 cSt kv 100° C., the di-octyl sebacate ester comprising about 20 weight percent of the oil formulation; d) the oil formulation having a viscosity index of greater than or equal to 208; and wherein the oil formulation exhibits a moisture corrosion resistance as measured by ASTM D7038/L-33-1 of at least 9.4 and a traction coefficient over a range of 0 to 30% slide-to-roll ratio of less than 0.02 (measured at a speed of 2 m/sec, a pressure of 1.00 GPa and a temperature of 80 deg. C.).
