A dialkylanilino-cyclohexane compound useful as an antioxidant has the following formula I or formula II: wherein Ar1 and Ar2 can be the same or different and each is an alkylaromatic group; each of R1, R2, R3, and R4 is independently selected from hydrogen or CR7R8; each of R5, R6, and R7 is independently selected from hydrogen and a substituted or unsubstituted C1 to C32 hydrocarbyl group; and each R8 is independently selected from hydrogen and a C1 to C2 alkyl group, provided that when, each of R1 and R2 is CR7R8 and each such R8 is other than hydrogen, R1 and R2 may be joined to form a five or six-membered ring, and provided further that when, each of R3 and R4 is an adjacent CR7R8 and each such R8 is other than hydrogen, R3 and R4 may be joined to form a five or six-membered ring.
