Gas prices in San Antonio have hit $1.99!

As of January 2026, the price for regular 87 octane gasoline in San Antonio typically ranges from $2.20 to $2.40, and it feels slightly cheaper compared to Dallas or Austin.

The best places to save on gas in San Antonio are definitely warehouse discount stores. If you have a membership, there's no need to think twice about Sam's Club and Costco. In particular, the Sam's Club near I-35 and Judson Road is often mentioned as having the lowest prices in the northeast area. The Costco near UTSA is also noticeably cheaper than the surrounding market, leading to long lines on weekends.

You can't overlook the gas stations next to H-E-B, which symbolizes Texas. H-E-B often provides additional benefits through its app or membership discounts, making the effective price even lower. Especially, the H-E-B gas stations around Loop 1604 or near 281 are quite competitive, making them popular among local residents.

Just a bit north of San Antonio, you can find the famous Buc-ee's in New Braunfels. It's considered a pilgrimage site for travelers, as it has a large number of gas pumps, allowing for quick turnover and aggressively priced fuel. This location helps to lower prices at nearby gas stations, making it worth a stop before a long drive.

Looking to the outskirts rather than the city center can also be a strategy. Gas stations right next to downtown or highways are often convenient but can be expensive. Just a little further out, like beyond Loop 1604 or in the western I-10 area, you can find relatively cheaper prices at major brand gas stations like Valero and Circle K.

In San Antonio, gas prices tend to rise as the weekend approaches, so it's better to fill up on Monday or Tuesday.

Instead of gas stations right off the highway, going just one block inward can often make a price difference. Some local gas stations offer slightly lower prices for cash payments, so paying in cash can help you save a bit more.

In San Antonio, using Sam's Club or Costco is a sure choice for saving on gas, and among regular gas stations, choosing H-E-B or the outer Valero locations can lead to significant savings.
