Gas prices in Wyoming

About gas prices in Wyoming

Wyoming hosts in-state refineries at Cheyenne (HollyFrontier, 52,000 barrels per day), Sinclair (Sinclair Wyoming, 92,000), and Casper (P66 Sinclair), making the state largely self-sufficient for fuel. The state gas tax is around 24 cents per gallon, on the lower end nationally. Cheyenne, Casper, and Laramie all see relatively competitive pricing. Maverik (a Utah-Wyoming chain), Loaf 'N Jug, Sam's Club (in Cheyenne), and Costco lead on value across Cheyenne, Casper, and Laramie. Yellowstone-area summer tourism creates seasonal price increases in the northwestern corner of the state, while the Powder River Basin coal country in northeastern Wyoming typically tracks the lowest pricing in the state due to direct refinery proximity and low local taxes.
