Finding cheap gas in Johnstown (80534)
Johnstown landed on the map for fuel in a big way when Colorado's first Buc-ee's opened here in 2024, a 74,000-square-foot travel center fronted by 116 pumps at the I-25 and County Road 48 interchange. That single location reshaped the local gas market, drawing drivers from across the northern Front Range and pressuring nearby stations to stay sharp.
The whole 2534 development area where I-25 meets US 34 has grown into a major retail and fuel node serving travelers between Denver, Loveland, and Fort Collins. Stations there price with that giant Buc-ee's in sight, which generally benefits drivers willing to compare before pulling in.
Away from the interstate, Johnstown's older town center has fewer options, so most fuel decisions here happen near the highway. Pricing the travel-center pumps against a standalone station along US 34 is worth the look, since the busiest stop is not automatically the cheapest.

How to save more on gas in Johnstown
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).
