Montana Gas Prices Remain Higher Than the National Average

Missoula, MT (KGVO-AM News) - Average gas prices in Montana have increased in 24 out of 33 weeks. After two straight weeks of declines, prices are back up again. Patrick De Haan is the head of petroleum analysis at GasBuddy, and he provided the current numbers.

“Average gasoline prices in Montana have risen 1.8 cents per gallon in the last week, averaging $3.23 per gallon today,” De Haan said. “Prices in Montana are 1.1 cents per gallon lower than a month ago and stand 25.6 cents per gallon lower than a year ago.”

As of Monday morning, many stations in Missoula still had their prices set to around $3.24 per gallon.

According to GasBuddy price reports, the cheapest station in Montana was priced at $2.86 per gallon yesterday, while the most expensive was $4.19 per gallon.

Montana is currently ranked 11th in the U.S. when it comes to the average price of gas, which is one spot higher than last week.

"The national average price of gasoline is unchanged in the last week, averaging $3.09 per gallon today,” De Haan said. “The national average is down 4.6 cents per gallon from a month ago and stands 27.9 cents per gallon lower than a year ago. The national average price of diesel has decreased 1.9 cents in the last week and stands at $3.67 per gallon.”

According to De Haan, gasoline prices continue to hover in the same territory where they’ve spent much of 2025 so far, in the low $3 per gallon range, as oil prices remain anchored in the $60 range.

“Price cycling markets once again led the biggest weekly price changes, with Ohio and Florida seeing a cycle and higher prices last week, while Michigan posted the largest drop and could be due for another jump in the cycle sometime this week,” De Haan said. “For the majority of motorists in non-cycling states, gas prices will likely remain near current levels as we head toward Labor Day. However, it’s worth watching developments around a potential peace deal between Russia and Ukraine. If such an agreement materializes, it could send oil prices lower on expectations that sanctions against Russia might be eased, effectively boosting global oil supply.”
