How to save more on gas in Casper
1. Use warehouse clubs
Costco and Sam’s Club typically price 15-25 cents per gallon below nearby stations. Membership pays for itself within a few fill-ups.
2. Fill up early in the week
Stations often raise prices Thursday for weekend demand. Fill up Monday through Wednesday to avoid the lift.
3. Keep tires properly inflated
Properly inflated tires improve fuel economy by up to 3 percent at current prices. Check pressure once a month.
4. Check back tomorrow
Prices can shift 10-20 cents overnight during volatile markets. A quick check before you leave home avoids paying yesterday’s spike.

Stations with cash and credit split pricing typically save an average of 10 cents per gallon when you pay cash.

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.
