Gas Prices in Waco, TX Today
Waco drivers are paying around $3.28 per gallon for regular unleaded as of late March 2026 — notably below the Texas average of $3.42 and well below the national average of $3.91. Waco's position at the midpoint of the I-35 corridor between Dallas and Austin creates a high-volume, competitive fuel market that benefits local drivers.
Why Waco Prices Stay Low
The I-35 corridor is one of the busiest truck freight routes in the United States, running from the Mexican border through San Antonio, Waco, Dallas, and north into Oklahoma. Waco sits exactly at the midpoint between two of Texas's largest metros. That geography produces an exceptionally competitive roadside fuel market — truck stops, travel plazas, and high-volume gas stations cluster along I-35 in Waco and compete aggressively for both commercial and passenger traffic.
High throughput means lower per-gallon margins. Stations near I-35 in Waco are selling thousands of gallons a day to through-traffic, which lets them price below what a suburban Dallas station can afford to charge. That price discipline affects the entire local market.
Baylor University's presence also shapes the market. With roughly 20,000 students, many of whom are on tight budgets, there's real demand for cheap fuel in the ZIP codes surrounding campus. Stations in 76706 and 76707 near the Baylor corridor know they're competing for student wallets.
Where to Find the Cheapest Gas in Waco
- 76706 — South Waco along I-35 and Valley Mills Drive, some of the best prices in the city — high-volume truck-stop-adjacent stations keep the whole corridor competitive
- 76707 — West Waco near Baylor's campus, student-demand-driven competition; several independent stations price aggressively
- 76701 — Downtown Waco, lower station density but check before assuming downtown prices are higher
- 76704 — East Waco, older residential area with a mix of independent operators; worth checking for outlier deals
- 76708 — North Waco, residential with commercial corridors along Hwy 84; mid-range pricing
- 76710 — Southwest Waco near Richland Mall, higher retail density and some competitive pricing on the Hewitt Drive corridor
- An affordable tire pressure gauge can improve your fuel economy by up to 3% — one of the easiest ways to save at the pump.
- A phone mount makes it easy to navigate hands-free to the cheapest station nearby.
The Flying J and Pilot truck stops along I-35 in the 76706 area — while primarily truck-focused — offer passenger vehicle fuel at prices that often undercut the surrounding city stations by 8–12 cents.
The Dallas-Austin Price Spread
Waco benefits from an interesting dynamic: it's below both Dallas and Austin in price, even though it sits between them on the I-35 corridor. Austin's prices tend to be higher due to California-style urban market premiums and the tech industry wage base that reduces price sensitivity. Dallas prices run higher than Waco for distribution-cost reasons. Waco captures neither penalty and benefits from I-35 corridor competition instead.
If you're driving between Dallas and Austin and need to fill up along the way, Waco is the right stop. Prices drop noticeably as you enter McLennan County from either direction.
Practical Tips for Waco Drivers
H-E-B has a strong presence in Waco with fuel centers at several locations, and their loyalty program ties grocery purchases to pump discounts. Regular H-E-B shoppers can knock 10–15 cents per gallon off an already-cheap Waco price.
Mid-week filling (Tuesday through Thursday) consistently beats Friday and weekend pricing across Waco's main commercial corridors. The I-35 through-traffic spike on Friday afternoons creates a brief demand surge that local stations use as cover to bump prices a few cents.
