Originally founded as Wainoco Oil in 1949, an oil and gas exploration company with production in both Canada and the U.S.

In October 1991, Wainoco purchased Frontier Oil, whose primary asset was a crude oil refinery in Cheyenne, WY.

Wainoco sold off its U.S. operations in 1995 because they weren't large enough to produce. The company sold off its Canadian operations in 1997 and concentrated on refining and marketing.

Wainoco changed its name to Frontier Oil Corporation in 1998.
