  • Chromium HVI-PAO bi-modal lubricant compositions
    Patent number: 8476205
    Abstract: The invention relates to oil compositions containing chromium catalyzed high viscosity index polyalphaolefins (HVI-PAO). In one embodiment the oil formulation comprises a chromium catalyzed HVI-PAO with a viscosity greater than 125 cSt kv 100° C. and a viscosity index greater than 100, a second base stock with a viscosity of at least 2 cSt kv 100° C. and less than 60 cSt kv 100° C. wherein the second base stock is at least 120 cSt kv 100° C. less than the chromium HVI-PAO, an ester with a viscosity of at least 2 and less than 6, the ester chosen from the group consisting of monoester, di-octyl sebacate and any combination thereof comprising more than 10 weight percent and less than 30 weight percent of the oil formulation, the oil formulation having a viscosity index of greater than 180.
