Gasoline prices in Massachusetts are up nine cents this week, the second consecutive week of increases, according to AAA Southern New England, which has an office in Framingham.

The recent surge in oil prices continues to drive an increase in gasoline prices. AAA’s July 16 survey of prices in Massachusetts found self-serve, regular unleaded averaging $3.479 per gallon, nine cents higher than a week ago, according to a press release.

The current price is eight cents above the national average for self serve unleaded of $3.39. A year ago at this time the Massachusetts average price was $3.71.

The range in prices in the latest AAA survey for unleaded regular is 34 cents, from a low of $3.35 to a high of $3.69. AAA advises motorists to shop around for the best prices in their area, and to make sure they and their passengers buckle up — every time.

AAA Fuel Saving Tip of the Week: Spark plugs must be in good condition. Some will last for 100,000 miles, but may need to be replaced more often.
