Gas Prices in Texas: What You Pay at the Pump and Why

Texas drivers consistently pay less for fuel than most of the country, and the latest pump prices show why the Lone Star State has a reputation for cheap gas. Regular unleaded averages $3.31 per gallon, mid-grade runs about $3.796, premium sits near $4.164, and diesel comes in at $4.288. Compared with the US national average of $3.867 for regular, Texas is roughly 55 cents cheaper per gallon, a gap that adds up fast for anyone driving the state's long highways.

Why Texas Fuel Is Cheaper Than Most States

The single biggest reason is geography and industry. Texas is the heart of American oil and gas production, home to the Permian Basin and the Gulf Coast refining complex around Houston, Port Arthur, and Corpus Christi. The state refines more crude oil than any other in the nation, so the supply chain between the wellhead, the refinery, and the pump is unusually short. Less transport distance and abundant local product mean retailers can price aggressively, and the 27 metro markets tracked across the state tend to compete hard with one another.

Taxes are the other half of the story. Texas levies a state motor fuels tax of 20 cents per gallon on both gasoline and diesel, a rate that has not changed since 1991 and is among the lower fuel taxes in the country. Stack the federal excise tax of 18.4 cents per gallon (24.4 cents on diesel) on top of that, and the combined tax burden is still modest compared with high-tax states like California or Pennsylvania. Because Texas has no state income tax, you might expect higher fuel levies to compensate, but the state instead leans on sales and severance taxes from its own energy sector to fund roads.

Diesel, Premium, and the Spread

Notice that diesel at $4.288 is the most expensive grade here, even pricier than premium gasoline. That is normal nationwide right now: diesel carries a higher federal tax, is tied to global distillate demand, and competes with heating oil and freight markets. For the many commercial trucks and farm operations that crisscross Texas, that spread matters. The premium-to-regular gap of about 85 cents reflects refining and additive costs rather than any local tax quirk.

How Texas Compares to Its Neighbors

Texas usually undercuts most of the region, though a few states trade places with it month to month. Neighboring Oklahoma is another energy producer that often posts similarly low numbers, while Tennessee and Indiana sit closer to the national mainstream. The common thread among the cheapest states is proximity to refining capacity and lighter tax loads, both of which Texas enjoys in abundance.

What Drives Day-to-Day Price Swings

Even within a cheap state, prices move. Hurricane season is the wild card on the Gulf Coast: a single storm that forces refineries offline can briefly push Texas prices above the national average, the rare occasion when the state's refining strength becomes a vulnerability. The annual switch to summer-blend gasoline each spring adds a few cents, and crude oil moves on the global market still set the baseline. Because so much product is local, however, Texas tends to recover from price spikes faster than import-dependent states on the coasts.
