Paying less than the Massachusetts average

  • Treat $3.79 as your benchmark. Stations well above it are charging a convenience premium; at or below it is a fair local deal.
  • Warehouse clubs and discounters beat it daily. Costco, Sam’s Club, Murphy USA, ARCO and similar brands consistently price below the average — our map finder highlights them near you.
  • Avoid interstate plazas. A mile off the highway is routinely cheaper.
  • Cut how much you burn. The fastest saving isn’t the station, it’s the right-hand pedal — see how to save money on fuel.
