Massachusetts gas prices down another 6 cents, yet remain well above the national average

The average price of a gallon of gasoline has dropped another 6 cents in Massachusetts to $3.26, and has now gone down 12 cents in two weeks.

Despite the steep drop, AAA Southern New England reports Tuesday that the Bay State's per-gallon price for self-serve, regular is 7 cents higher than the national average.

Massachusetts prices are now 17 cents lower than a month ago and 12 cents lower than at the same time a year ago.

AAA says prices are being kept down by low demand combined with abundant supply on the global oil market.

Prices ranged from a low of $3.05 for a gallon of self-serve, regular to a high of $3.53.
