A gear oil lubricant composition and method of operating a vehicle with t he composition. The composition may include a first olefinic lubricant having a viscosity ranging from about 80 centistokes to about 150 centistokes at 100.degree.C a nd a second olefinic lubricant having a viscosity ranging from about 2 centistokes to about 15 centistokes at 100 .degree.C. A ratio of the first olefinic lubricant to the second olefinic lubricant may range from about 2:1 to about 8:1. Additionally, the compositi on may include an alkylated naphthalene base oil, a boronated ashless dispersant, a t least one hindered phenol antioxidant, at least one alkylated diphenylamine antioxidan t, and a gear oil additive package having an active phosphorus content of less than about 700 ppm and an active sulfur content of less than about 3 wt. %. The gear oil lubricant composition may contain less than about 0.1 percent by weight antioxidant composition based on a total weight of the lubricant composition.
