Diesel fuel prices in Utah have reached an all-time high, with the average cost for a gallon of self-serve diesel hitting $6.58, according to data from Triple-A released on Sept. 24, 2026.
Significant Price Increases
The surge in fuel costs marks a significant upward trend for Utah consumers. The current average price of $6.58 per gallon represents a 44-cent increase from just one week prior to Sept. 24, 2026.
This spike in diesel costs is part of a broader trend of exceptionally high fuel prices affecting the state, similar to patterns observed across much of the nation.
Yearly Cost Comparison
The cost of diesel has risen sharply over the last twelve months. The current price is $2.85 higher per gallon than it was at this time last year.
As reported by Mid-Utah Radio, Utah is currently dealing with these exceptionally high fuel prices, which have reached a record level for the state.
Economic Impact
The record-breaking prices for diesel fuel come as the state continues to manage high costs for energy and transportation.
