BOSTON (AP) - The cost of a gallon of gasoline in Massachusetts is up another 4 cents in the past week, to its highest level since early January.
AAA Northeast reports Monday that self-serve, regular is selling for an average of $2.28 per gallon.
The Massachusetts price is 12 cents lower than the national average, but 20 cents per gallon higher than the in-state average a year ago.
AAA found self-serve, regular selling for as low as $2.15 per gallon and as high as $2.44.
AAA says prices are climbing amid production cuts by OPEC nations, seasonal refinery maintenance and increasing demand.
