Estimated average retail price of regular-grade gasoline across all formulations, including taxes, in EIA's West Coast petroleum district excluding California. The six-state region contains Alaska, Arizona, Hawaii, Nevada, Oregon, and Washington.
Arizona compared with the U.S.
Regular gasoline price- Arizona
- $4.823/gal
- United States
- $4.071/gal
The regional average was 75.2 cents per gallon higher, or about 18.5% above the U.S. average.
Both figures are EIA weekly retail estimates for regular gasoline, including taxes, for the week of August 31, 2026. The Arizona-side figure is a six-state regional proxy, not an Arizona statewide estimate. Recent weekly prices

How it was measured: EIA does not publish a current Arizona statewide weekly gasoline-price series. FactVote therefore uses EIA's West Coast (PADD 5) Except California series as the smallest current EIA retail region that includes Arizona, displays the published dollars-per-gallon value, and calculates changes from the prior-week and nearest year-earlier weekly observations.
Keep in mind- This is a six-state regional average, not an Arizona statewide gasoline-price estimate, and it is excluded from state rankings.
- The regional average combines Alaska, Arizona, Hawaii, Nevada, Oregon, and Washington and can mask substantial differences among those states, communities, and individual stations.
- The nominal weekly price does not identify why prices changed or establish the effect of any tax, bill, executive action, fuel formulation, or market event.
