Texas Gas Prices and Why They Are What They Are
Prices as of July 06, 2026, per AAA · Updated July 06, 2026
As of July 06, 2026, regular gasoline in Texas averages $3.31/gallon (the 2nd-lowest in the U.S.), per AAA — 0.52 below the national average of $3.83. Diesel averages $4.19. State fuel taxes and fees add 20.0¢/gallon on top of the 18.4¢ federal excise.
Where the $3.31 goes
| Component | $/gallon | Share | Source |
|---|---|---|---|
| Crude oil (national cost, WTI June 2026) | 2.04 | 62% | EIA |
| Federal + Texas fuel taxes (18.4¢ + 20.0¢) | 0.38 | 12% | Tax Foundation |
| Refining, distribution, margins & embedded program costs (residual) | 0.89 | 27% | computed |
Crude oil costs every state's refiners roughly the same, so Texas'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.
