Gasoline prices in Massachusetts are down one cent this week, according to AAA Northeast.

AAA Northeast’s February 3 survey of prices in Massachusetts finds self-serve, regular unleaded averaging $2.51 per gallon. Massachusetts’s price is 4 cents above the national average of $2.47. A year ago at this time, the average price in Massachusetts was 12 cents lower at $2.39 per gallon.

“Gas prices are pushing cheaper for two reasons. Crude oil prices are $10 less a barrel than one month ago and U.S. gasoline stocks sit at an all-time record high,” said Mary Maguire, Director, Public and Legislative Affairs. “Cheaper crude and healthy stock levels mean motorists can expect prices to continue to decline this month.”

The range in prices in the latest AAA survey for unleaded regular is 80 cents, from a low of $2.25 to a high of $3.05. AAA advises motorists to shop around for the best prices in their area. Please remember to slow down and move over for any emergency vehicles on the side of the road.
