Finding cheap gas in Boulder (80304)
North Boulder, or NoBo, runs from the Old North End up Broadway into the arts district, an artsy, increasingly built-up stretch backed against the foothills. Stations are genuinely sparse here, since much of the ZIP is residential and the city's growth limits and bike-first culture leave little room for big fuel plazas, so locals lean on the handful along Broadway and 28th Street.
The dependable value sits down on 28th Street, where the Glenwood Grove area and the busier commercial corridor host grocery-linked fuel and higher-volume brands. The Old North Boulder grid is mostly quiet residential streets, so plan to drive to the corridor to fill.
Boulder runs expensive across the board, a function of affluence, limited station count, and a community that bikes more than it drives. The best move is to compare the 28th Street options and stack a King Soopers or Safeway fuel reward, which is where the real savings live in this part of town.

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).
