With just 8 E85 stations, Massachusetts represents the best New England has to offer for flex fuel drivers—which isn't saying much. Distance from Midwest ethanol production and limited state support have kept E85 infrastructure sparse.
Massachusetts sits 1,000+ miles from Corn Belt ethanol plants. Unlike petroleum, ethanol cannot travel through existing pipelines—it attracts water and is mildly corrosive. This adds $0.25-$1.00+ per gallon in transportation costs. There are zero ethanol production facilities anywhere in New England.
Massachusetts has focused policy attention and incentives on electric vehicles rather than biofuels, leaving E85 without meaningful state support.
Stations cluster around Greater Boston and along the Massachusetts Turnpike (I-90): Mass Turnpike Gulf stations at Westborough and Charlton Service Plazas, Shell stations in Cambridge and Charlestown, and Gulf stations near Logan Airport and in Chelsea.
Western Massachusetts beyond Charlton has no E85 stations. The I-95 corridor lacks dedicated coverage. Northern Massachusetts near New Hampshire has nothing. Cape Cod is minimally served.
E85 must be roughly 23% cheaper than regular gasoline to break even on fuel economy. Verify station availability before traveling; some locations report inconsistent ethanol content.
The Mass Pike is your friend—Gulf stations at Westborough and Charlton provide the most reliable highway coverage. For travel beyond Massachusetts, plan to use regular gasoline or identify Pennsylvania stations if heading west.

Verify station availability before traveling; some locations report inconsistent ethanol content. Across Massachusetts's 8 public E85 stations, actual savings vary by retailer and regional transport costs.

Only factory-certified flex fuel vehicles (FFVs) should run E85. Check your Massachusetts vehicle for a yellow fuel cap, a "Flex Fuel" badge, an E85 sticker inside the fuel door, or confirm via the owner's manual or VIN decoder. Using E85 in a non-FFV can damage fuel lines, injectors, and seals — see our full FFV identification guide.
