1. A lubricant oil composition comprising
(a) a first base oil component in the amount of 1 weight % to 50 weight % based on the total weight of the oil composition, wherein the first base oil component comprises a compound of Formula (I) wherein R is (C18-C40)alkyl, (C5-C40)cycloalkyl, (C5-C40)aryl, (C7-C9)aralkyl; wherein the aralkyl is optionally substituted with (C1-C36)alkyl, or (C6-C40)alkenyl; and (b) a second base oil component in the amount of 0.1 weight % to 80 weight % based on the total weight of the oil composition, wherein the second base oil component comprises one or more of a polyalphaolefin (PAO) base stock, Group II base stock, Group III base stock, Group V base stock, GTL base stock, alkylated benzene base stock, and ester base stock;wherein the composition has a kinematic viscosity at 100° C. of 7.6 cSt or less, a Noack volatility at 250° C. of less than 10%, and a viscosity index of at least 90. |
