Gasoline prices in Massachusetts are down four cents this week, according to
AAA Southern New England, which has an office in Framingham off Route 9.

AAA’s March 4 survey of prices in Massachusetts found self-serve, regular unleaded averaging $3.729 per gallon, four cents less than a week ago. Prices locally are up 13 cents over the past month.

The current price is two cents below the national average for self serve unleaded of $3.74. A year ago at this time the Massachusetts average price was $3.73.

The range in prices in the latest AAA survey for unleaded regular is 30 cents, from a low of $3.59 to a high of $3.89.

AAA Fuel Saving Tip of the Week: If your vehicle’s engine does not need premium fuel, using anything other than regular is simply a waste of money.
