AUGUSTA — Maine residents are paying almost 6 cents per gallon more for a gallon of gas this week.

Price-monitoring website MaineGasPrices.com reports Tuesday that the average retail price of gas in Maine has jumped to $3.73 in the past week, which is 12 cents per gallon higher than the national average.

In-state prices are still almost 16 cents per gallon lower than on the same day a year ago but less than a penny lower than a month ago.

The averages are based on a survey of more than 1,200 Maine gas stations.
