Gas Prices in Houston
Houston's proximity to Gulf Coast refineries and abundant station competition from H-E-B Gas, Murphy USA, and Valero keeps prices among the lowest for any major US metro. The city's car-dependent sprawl means residents average 17+ miles of daily driving, making price-per-gallon savings meaningful.
Prices at individual stations can vary by 5–15 cents within the same city depending on brand, location, and local competition. Use apps like GasBuddy to find the cheapest station near you in Houston.
