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 mm/s to 600 mm/s, a kinematic viscosity (ASTM D445, 100° C.) of from 20 mm/s to 70 mm/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 mm/s to 3500 mm/s, a kinematic viscosity (ASTM D445, 100° C.) of from 60 mm/s to 300 mm/s, a viscosity index (ASTM D2270) of from 150 to 250, and a pour point (ASTM D97) of from −50° C. to −20° C.
