Lamar Gas & Diesel Watch: Loaf ’N Jug estimated regular + diesel prices

Lamar CO Gas & Diesel Watch — The latest price check for Loaf ’N Jug (300 N Main St) shows estimated regular at $3.88/gallon and estimated diesel at $4.48/gallon. Way notes these are estimated prices, which can differ from what drivers see at the pump.

Colorado averages (AAA): easing since yesterday and last week

Price as of 6/25/26: AAA listed Colorado’s statewide average regular at $3.7870 (vs. $3.8340 yesterday; $3.9790 week ago; $4.6460 month ago; $3.2240 year ago). AAA listed diesel at $4.4900 (vs. $4.5270 yesterday; $4.7600 week ago; $5.4770 month ago; $3.5000 year ago).

U.S. and Rocky Mountain diesel direction (EIA): lower than a week ago

In EIA’s June 23, 2026 weekly update (covering the week ending 6/22/26), U.S. regular gasoline averaged $3.914, down from $4.052 one week earlier. U.S. on-highway diesel averaged $4.832, down from $5.059 the week before. For the region that includes Colorado, Rocky Mountain (PADD 4) diesel averaged $4.795, down from $5.019 a week earlier.

So what for Lamar drivers and local fleets?

At this Way listing, the regular-to-diesel spread is about 60 cents per gallon ($4.48 minus $3.88). That gap matters for anyone who doesn’t just buy regular—delivery and service businesses, trades crews, and households with diesel vehicles tend to feel the impact when diesel moves on its own.

For planning weekend travel or workweek routing, compare prices on the fuels you actually use: regular and diesel can change on different schedules, and statewide averages help with direction but aren’t the same as what one Lamar station charges.
