Denver gas and diesel still ease overall, but regular tops $4
Denver’s latest AAA check shows regular gas at $4.054 and diesel at $4.889, both below Colorado and U.S. averages even after a small daily uptick.
Denver drivers got a little more breathing room in AAA’s latest metro check, even though the day-to-day move ticked up slightly. Regular gas averaged $4.054 a gallon in Denver on June 10, 2026, while diesel averaged $4.889. Regular was up from $4.029 yesterday and diesel was up from $4.873, but both fuels were still below their week-ago, month-ago, and year-ago levels.
Regular gas and diesel are still moving differently
Regular gas is down from $4.204 a week ago and $4.329 a month ago, though it remains above the $2.961 average from a year ago. Diesel followed the same broader direction, falling from $5.059 a week ago and $5.392 a month ago, even though it is still well above $3.150 a year ago. Diesel remains the bigger pain point for contractors, delivery fleets, restaurants, and other businesses that burn fuel every day.
Denver is still cheaper than Colorado and the nation
Denver’s regular price is still below the Colorado average of $4.270 and the U.S. average of $4.151. Diesel also sits below both benchmarks, with Colorado at $5.051 and the U.S. at $5.303. That gives local commuters, households, and road-trippers a useful benchmark when comparing stations around town.
What to watch next
The federal Energy Information Administration’s latest weekly update also showed U.S. gasoline and diesel prices lower than a week earlier, which fits the softer overall trend. For anyone planning summer driving, the practical takeaway is simple: Denver fuel costs are still high, but the bigger picture has been easing. If you’re filling up locally, share the highest and lowest pump prices you’re seeing.
