Gas Prices in Montana Drop Again, Higher Than the National Average

Missoula, MT (KGVO-AM News) - Average gas prices in Montana have increased in 25 out of 51 weeks, but haven’t increased since September 2, 2025. Patrick De Haan is the head of petroleum analysis at GasBuddy, and he provided the current numbers for this week.         

“Average gasoline prices in Montana have fallen 2.2 cents per gallon in the last week, averaging $2.83 per gallon today,” De Haan said. “Prices in Montana are 15 cents per gallon lower than a month ago and stand 10.3 cents per gallon higher than a year ago."  

As of Monday morning, most stations in Missoula had their prices set to $2.83 per gallon. According to GasBuddy price reports, the cheapest station in Montana was priced at $2.50 per gallon yesterday, while the most expensive was $3.34 per gallon. 

Montana is currently ranked 21st in the U.S. when it comes to the average price of gas, which is the same spot as last week.

"The national average price of gasoline has fallen 5.7 cents per gallon in the last week, averaging $2.79 per gallon today,” De Haan said. “The national average is down 26.4 cents per gallon from a month ago and stands 21.4 cents per gallon lower than a year ago. The national average price of diesel has decreased 4.3 cents compared to a week ago and stands at $3.58 per gallon.”                

For the fourth straight week, De Haan said the national average price of gasoline has fallen, once again setting a new multi-year low.  

“Conditions remain ripe for some of the lowest seasonal gas prices in five years,” said De Haan. “Oil prices continue to struggle amid rising U.S., Canadian, and OPEC+ oil production, while refinery output remains near some of the highest seasonal levels in years— factors that are likely to keep gas prices under pressure over the weeks ahead. We’re continuing to see some gas prices below $2 per gallon in the nation’s cheapest states, now at more than 125 gas stations. Diesel prices have also seen some relief, though inventories remain tight, keeping the national average higher than a year ago.”

For those traveling across state lines, keep in mind the extreme volatility in prices that can occur between states and save yourself 20-80 cents per gallon by filling up on the cheaper side.
