Utah's average price for regular gasoline decreased by two cents to $4.70 per gallon as of Oct. 23, 2026, according to Gasolytics. The drop comes as the national average for a gallon of regular gasoline fell to $4.2926 on Oct. 23, according to AAA.
Regional Price Variations
The slight decrease in Utah's fuel costs follows a period of higher prices. On Oct. 16, 2026, Utah's regular gas price was reported at $4.70 per gallon, which was $0.41 higher than the national average at that time, according to Gasolytics.
Local market data from Oct. 23, 2026, shows significant variation in prices across Utah metropolitan areas. Provo-Orem reported a regular gas price of $4.62 per gallon, while Salt Lake City reported $4.63. Ogden recorded $4.64, Logan reported $4.68, and St. George reported the state's highest regular gas price at $4.87.
Diesel prices also vary by region. On Oct. 23, 2026, the cheapest diesel in Utah was $6.45 per gallon. Regional diesel prices included $6.43 in Provo-Orem, $6.42 in Salt Lake City, $6.38 in Ogden, $6.46 in Logan, and $6.54 in St. George, according to Gasolytics.
National Trends and Crude Oil
While Utah's prices saw a minor daily decline, the national landscape has seen broader shifts. AAA reported on Oct. 22, 2026, that the national average for regular gasoline fell 6 cents over the previous week to $4.27. This decline is attributed to the transition to winter-blend gasoline, which is less expensive to produce and cheaper for consumers.
However, experts noted that high crude oil prices are preventing more significant price drops. As of Oct. 22, 2026, crude oil prices were nearing $100 per barrel due to instability in the Strait of Hormuz. Specifically, WTI fell 67 cents to settle at $97.15 per barrel at the close of the Wednesday trading session.
Supply and Demand Factors
The volatility in energy markets comes during a period of record-setting costs. AAA reported on Oct. 22, 2026, that this month was poised to become the most expensive October on record for gas prices, following similar record highs in August and September 2026.
Data from the Energy Information Administration (EIA) indicated that gasoline demand increased from 8.40 million barrels per day to 8.98 million barrels per day last week. During the same period, total domestic gasoline supply decreased from 208.3 million barrels to 205.3 million barrels, while gasoline production rose from 9.23 million barrels per day to 9.75 million barrels per day.
Utah Fuel Tax Rates
Utah also maintains specific tax rates on fuel. According to the Utah State Tax Commission, the current rate for motor fuels is $0.379 per gallon, effective Jan. 1, 2026.
Other fuel-related taxes in the state include an aviation fuel tax of $0.090 per gallon for non-federally certificated air carriers and $0.040 per gallon for federally certificated air carriers, both effective July 1, 2001. A $0.0065 per gallon Environmental Assurance Fee has been in effect since Jan. 1, 2015.
National Market Rankings
Despite the recent two-cent drop in Utah, the state remains among the most expensive markets in the country. According to AAA, Utah was ranked as one of the top 10 most expensive gasoline markets in the nation, with a reported price of $4.72 per gallon.
