Finding cheap gas in San Antonio (78240)
The South Texas Medical Center defines this Northwest Side ZIP, a cluster of hospitals and clinics including Methodist and University Hospital that brings a steady daytime population of staff, patients, and visitors. That reliable demand keeps the stations around the Medical Drive and Wurzbach corridors well used.
Sitting between I-10 and the Bandera Road side of town, the area mixes medical campuses with established apartments and neighborhoods. Grocery fuel in the retail centers serving those residents tends to set the lower prices, while the stations right by the hospital entrances lean on captive convenience.
Commuters and medical workers funnel onto I-10 and Loop 410 nearby, so the ramp-side pumps price accordingly. For a better deal, the stations a little deeper into the Wurzbach and Fredericksburg Road retail usually undercut the freeway-facing corners. With a hospital shift always rolling over, demand here is steadier than in a purely residential ZIP, which gives the busier corridors enough volume to keep prices competitive.

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.
