How to save more on gas in Round Rock
1. Use warehouse clubs

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.

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.
