Abstract: Gear oil compositions including a first oil basestock and a second basestock. The first basestock includes a Group II bright stock having a kinematic viscosity (ASTM D445, 40° C.) of from 250 mm2/s to 600 mm2/s, a kinematic viscosity (ASTM D445, 100° C.) of from 20 mm2/s to 70 mm2/s, a viscosity index (ASTM D2270) of from 80 to 120, and a pour point (ASTM D97) of from −50° C. to −20° C. The second basestock includes a polyalphaolefin (PAO) basestock having a kinematic viscosity (ASTM D445, 40° C.) of from 500 mm2/s to 3500 mm2/s, a kinematic viscosity (ASTM D445, 100° C.) of from 60 mm2/s to 300 mm2/s, a viscosity index (ASTM D2270) of from 150 to 250, and a pour point (ASTM D97) of from −50° C. to −20° C.

Abstract: Grease compositions may be made from an oil basestock. For example, a grease composition may include: an oil basestock having: a kinematic viscosity (ASTM D445, 40° C.) of from 320 cSt to 520 cSt, a kinematic viscosity (ASTM D445, 100° C.) of from 22 cSt to 36 cSt, a viscosity index (ASTM D2270) of from 80 to 119, a pour point (ASTM D97) of −6° C. or less, and a saturate content (ASTM D7419) of 90 wt % or greater; and from 0.5 wt % to 15 wt % of a thickener, by total weight of the grease composition.
