Montana Gas Prices Crack the Top 10 in the Nation

Missoula, MT (KGVO-AM News) - Average gas prices in Montana have now increased in 23 out of 28 weeks. Prices dropped for just the fifth time in 2025 last week, but they are on the rise again this week. 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 cent per gallon in the last week, averaging $3.27 per gallon today,” De Haan said. “Prices in Montana are 6.3 cents per gallon higher than a month ago and stand 26.3 cents per gallon lower than a year ago.”         

As of Monday morning, many stations in Missoula still had their prices set to around $3.26 per gallon.

Montana is currently ranked 9th in the U.S. when it comes to the average price of gas, which is three spots higher than last week.                         

“The national average price of gasoline has risen 2.0 cents per gallon in the last week, averaging $3.11 per gallon today,” De Haan said. “The national average is down .5 cents per gallon from a month ago and stands 37.9 cents per gallon lower than a year ago. The national average price of diesel has increased 3.2 cents in the last week and stands at $3.68 per gallon.”

With oil prices posting a modest uptick last week, the national average price of gasoline also inched slightly higher. 

“Just over half of U.S. states saw increases, while nearly two dozen saw declines,” said De Haan. “As we approach the midpoint of the summer driving season, gasoline inventories remain just below average, while diesel inventories are considerably tighter—keeping upward pressure on diesel prices. While renewed tariff discussions could weigh on oil markets due to concerns about economic growth, absent any major developments, we expect the national average to remain rangebound in the low-$3 per gallon area, where it has spent much of the summer.”
