Finding cheap gas in San Antonio (78216)
This is San Antonio's Uptown, built around North Star Mall at the high-traffic corner of San Pedro Avenue and Loop 410, just a couple of miles from the international airport. It is a major retail district, and the dense run of shopping along San Pedro and the Loop supports a thick field of competing gas stations.
The airport proximity adds a wrinkle: rental returns and travelers topping off can prop up prices at the stations closest to the terminals along the Loop 410 frontage. Step back toward the San Pedro retail corridor and the everyday competition usually delivers a better number.
With Loop 410 and US-281 both threading through the area, the freeway-adjacent pumps price for through traffic and travelers. Buying along the interior commercial streets near the mall tends to beat the convenient airport-side corners. Because Uptown packs so much retail into a small footprint, there is rarely just one station to choose from, and the gap between the airport-side pumps and the San Pedro corridor is usually worth the short hop.

How to save more on gas in San Antonio
1. Use warehouse clubs
Costco and Sam’s Club typically price 15-25 cents per gallon below nearby stations. Membership pays for itself within a few fill-ups.
2. Fill up early in the week
Stations often raise prices Thursday for weekend demand. Fill up Monday through Wednesday to avoid the lift.
3. Keep tires properly inflated
Properly inflated tires improve fuel economy by up to 3 percent at current prices. Check pressure once a month.
4. Check back tomorrow
Prices can shift 10-20 cents overnight during volatile markets. A quick check before you leave home avoids paying yesterday’s spike.
5. Pay cash at split-pricing stations
Stations with cash and credit split pricing typically save an average of 10 cents per gallon when you pay cash.

About gas prices in Texas
Texas runs one of the lowest gas tax rates in the country at 20 cents per gallon, and its location next to the Gulf Coast refining belt (which produces roughly 40 percent of US refined fuel) keeps prices consistently below the national average. Buc-ee's, Costco, and Sam's Club draw the cheapest pump prices across Houston, Dallas, Austin, and San Antonio metros, while HEB Fuel and Kroger Fuel are competitive grocery options. Watch for noticeable Friday afternoon hikes in Houston, Dallas, and Austin during peak summer driving season, when local demand briefly outpaces supply.
