Gas prices in Utah
EIA does not publish a weekly retail gasoline price for Utah. The federal survey prices the district Utah sits in, Rocky Mountain (PADD 4), at $4.27 per gallon in the week of August 31, 2026, 20 cents above the US average of $4.07. Pump prices inside the district vary around that figure.
On-highway diesel for Rocky Mountain (PADD 4) is $5.55, 4 cents below the US diesel average of $5.60. EIA runs the diesel survey for California and the regions only, so every other state carries its district figure here. A temporary six-cent cut runs 1 July to 31 December 2026 before the rate reverts to the CPI-indexed level.

Utah's pump-price cost stack

Border-state comparison
How the neighbours read in the same survey week. Neighbours inside the same EIA district carry the same published figure, which is why several rows can match exactly.
Use the border comparator to compute the per-tank difference where the two states fall in different EIA districts.
