How to save more on gas in Longmont

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).
