Finding cheap gas in Longmont (80501)
Longmont spreads across northeastern Boulder County into western Weld, and US Highway 287 runs through its center as Main Street, the artery that carries most of the city's fuel traffic north toward Loveland and south toward Denver. The historic downtown blocks around Main hold the old-town character, but the gas stations gather on the wider commercial stretches.
The Main Street corridor and the area where the Ken Pratt Boulevard and Highway 119 Diagonal meet hold the densest cluster of stations, and competition along them keeps Longmont generally cheaper than nearby Boulder. Grocery and big-box fuel centers usually beat the standalone stops.
Because the Diagonal connects quickly to I-25 on the east and Boulder on the southwest, some stations near those junctions price for through traffic. Filling at a Main Street or Ken Pratt grocery anchor rather than a junction station is the dependable way to save here.

How to save more on gas in Longmont
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).
