How much is a gallon of gas in Maine?

Regular gasoline in Maine averages $4.53 per gallon as of mid-May 2026 per AAA’s state tracker, up roughly 50 cents from a month earlier on the back of crude oil pressure tied to Middle East tensions. That sits modestly above the US national average ($4.30 to $4.45 in the same window). Maine is car-dependent outside Portland: Bangor, Lewiston, Augusta, the coast, and rural inland areas all require driving for daily life. CostLiving’s moderate Maine budget carries a $122-a-month transport line, which buys roughly 27 gallons at the current price, enough for a 600-mile commute month. Heating oil (a similar refined-fuel product) tracks the same wholesale pressure and matters more in winter. AAA Maine remains the most current daily source.
