How to save more on gas in Boulder
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 Colorado
Colorado's state gas tax is around 22 cents per gallon, and the Front Range corridor draws fuel from the Suncor refinery in Commerce City plus pipeline supply from Wyoming and Salt Lake City. The state requires an oxygenated winter blend from November through February at high-altitude metros, which adds 5 to 10 cents per gallon during those months. King Soopers (Kroger), Costco, and Sam's Club are the dependable cheap options across Denver, Colorado Springs, and Fort Collins. Mountain resort towns (Aspen, Vail, Breckenridge) typically run 30 to 50 cents above Front Range averages due to long supply hauls and limited local competition (no Costco or Sam's Club within 50 miles of Aspen).
