Alabama Gas Prices and Why They Are What They Are
Prices as of September 04, 2026, per AAA · Updated September 04, 2026
As of September 04, 2026, regular gasoline in Alabama averages $3.80/gallon (the 9th-lowest in the U.S.), per AAA — 0.27 below the national average of $4.07. Diesel averages $5.57. State fuel taxes and fees add 31.0¢/gallon on top of the 18.4¢ federal excise.
Where the $3.80 goes
| Component | $/gallon | Share | Source |
|---|---|---|---|
| Crude oil (national cost, WTI August 2026) | 2.00 | 53% | EIA |
| Federal + Alabama fuel taxes (18.4¢ + 31.0¢) | 0.49 | 13% | Tax Foundation |
| Refining, distribution, margins & embedded program costs (residual) | 1.31 | 34% | computed |
Crude oil costs every state's refiners roughly the same, so Alabama's position comes from the tax line and the residual: refining capacity and logistics, fuel-specification requirements, and any carbon or clean-fuel program costs embedded in the pump price.
