Wyoming avg
Wyoming state gas tax: 24¢/gal · Federal tax: 18.4¢/gal · Total tax: ~42¢/gal
Wyoming is an oil and gas producing state with two refineries, which helps keep prices moderate. However, its vast geography means many towns are far from fuel distribution hubs, requiring expensive truck delivery. Cheyenne and Casper see the most competitive pricing. Remote areas like Jackson Hole pay a significant premium.
