According to GasBuddy price reports, the cheapest station in Montana was priced at $2.84 per gallon yesterday, while the most expensive was $3.64 per gallon.

Montana is currently ranked 12th in the U.S. when it comes to the average price of gas, which is two spots higher than last week.

“The national average price of gasoline has fallen 4.2 cents per gallon in the last week, averaging $3.08 per gallon today,” De Haan said. “The national average is down 8.6 cents per gallon from a month ago and stands 50.6 cents per gallon lower than a year ago. The national average price of diesel has decreased 2.8 cents in the last week and stands at $3.47 per gallon.”

Even with oil prices jumping more than $4 per barrel compared to last week, De Haan said the national average price of gasoline has resumed its decline as refineries wrap up seasonal maintenance and prepare to boost output.

"Forty states have seen average gasoline prices fall over the last week, while just ten have seen increases, most notably on the West Coast, where another refinery fire in Northern California once again disrupted gasoline production,” De Haan said. “As we approach Memorial Day, gas prices may see some minor fluctuations, but for now, I don't expect any significant changes to the national average, with prices staying near their lowest seasonal level since 2021."
