Gas Prices in Austin Today
Austin drivers are paying around $3.30–$3.40 per gallon for regular unleaded as of mid-March 2026 — slightly above the Texas state average of $3.26 and below the national average of $3.72. Texas generally enjoys some of the cheapest gas in the country thanks to Gulf Coast refinery proximity, but Austin consistently runs 5–10 cents above Houston and San Antonio because of its inland position. The ongoing Iran conflict has pushed prices sharply higher everywhere, with crude oil surging past $110 per barrel and Strait of Hormuz disruptions threatening roughly 20% of global oil supply.
Why Austin Pays More Than Houston
Austin sits about 160 miles northwest of the Houston Ship Channel refinery complex, the largest concentration of refineries in the United States. Every gallon of gas sold in Austin has to be trucked up from the coast, and that transportation cost adds a consistent premium over coastal cities. Houston and Beaumont drivers fill up essentially at the source; Austin drivers pay the freight markup.
This gap has widened during the Iran crisis. When wholesale prices jump 74 cents in a single month, the transportation cost from the Gulf Coast amplifies the increase. Austin's fast-growing population also puts more demand on fuel distribution infrastructure that was built for a smaller metro.
Where to Find the Cheapest Gas in Austin
Austin's price variation runs about 20–30 cents between the cheapest suburban stations and the most expensive spots near downtown and the university area. The I-35 corridor through north Austin and the suburbs generally offers the best pricing.
Search by ZIP code:
- Downtown / UT Campus area — 78701 — convenient but typically the most expensive in the metro
- South Austin / Manchaca — 78704, 78745 — moderate pricing, good station density along Lamar and Manchaca
- Pflugerville — 78660 — north suburban corridor, consistently competitive pricing
- Round Rock — 78681, 78664 — strong station competition along I-35, often the cheapest in the metro
- Keeping a tire pressure gauge in your glove box helps maintain proper inflation — underinflated tires waste up to 3% of your fuel.
- Running a fuel system cleaner through your tank once a season keeps injectors clean and your engine running efficiently.
The I-35 Corridor Advantage
I-35 runs straight through Austin and connects San Antonio to the south with Dallas-Fort Worth to the north. This corridor is lined with high-volume truck stops and retail stations competing aggressively for commuter and through-traffic business. Stations along I-35 in Round Rock, Pflugerville, and north Austin tend to price 10–15 cents below stations in central Austin or west of MoPac.
If your daily commute crosses the I-35 corridor, filling up along that route rather than near downtown can save $3–5 per tank.
H-E-B and Warehouse Club Pricing
H-E-B, the dominant Texas grocery chain, operates fuel stations at many of its Austin-area locations. Their pricing is consistently below surrounding stations, and their loyalty program offers periodic fuel discounts. Costco locations in north and south Austin also undercut the market by 20–30 cents per gallon, though peak-hour lines can run 10–15 minutes.
Iran Conflict and Texas Gas Prices
Texas is better positioned than most states to weather the Iran-driven crude surge because the Gulf Coast refinery corridor processes both domestic and imported crude. But even Texas isn't immune to a 26.9% jump in global oil prices. The Strait of Hormuz disruptions have tightened global supply, and Austin drivers should expect elevated prices through spring 2026 at minimum.
