Finding cheap gas in Austin (78738)
Out where Highway 71 meets RM 620 in the rolling Hill Country west of the city, 78738 takes in Bee Cave, Lakeway, and The Hills, some of the most affluent terrain in the Austin metro. The Hill Country Galleria, an open-air center with more than a hundred shops, is the retail and social hub, and the fuel market reflects the higher-income, lower-density character of the area.
Stations cluster around the Galleria and the Highway 71 and 620 corridors, since the residential pockets here are spread thin across the hills with long stretches between commercial nodes. That means fewer pumps overall, and the convenience-store prices in this part of the metro can run on the higher side.
Most residents reach downtown in 25 to 40 minutes via Highway 71, and many fuel up at the Galleria-area stations on the way in or out. If you are passing through toward the lake or the Hill Country beyond, topping off near Bee Cave beats the sparser options further west on 71.

How to save more on gas in Austin
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.
