What shapes the price in Boston
Boston's average price reflects local conditions within Massachusetts on top of the broader state and regional factors that set a baseline price: the density of nearby stations and how directly they compete on price, local delivery and real estate costs, and how close the metro area sits to a refinery or major fuel terminal. Large metro areas often show more day to day price movement than a statewide average, since a shift in local competition or a nearby supply disruption can move prices before it shows up in the wider state figure.
Gasoline prices also move with the seasons, largely independent of any single region's own tax or supply situation. Prices typically climb heading into the summer driving season, partly because refineries switch to a more expensive, lower-emission summer fuel blend required in many areas, and partly because demand rises with vacation travel. Prices commonly ease again after Labor Day as refineries switch back to cheaper winter-blend fuel and driving demand drops, though crude oil price swings, refinery outages, and hurricanes affecting Gulf Coast refining capacity can override the normal seasonal pattern in either direction.

The calculator on this page is pre-filled with Boston's current regular gasoline price so you can get a cost estimate without looking the number up separately. If you know your vehicle runs on premium or diesel, swap in the corresponding price shown above instead of the pre-filled regular price, since the gap between grades commonly runs 40 cents a gallon or more and materially changes the result for a longer trip.
Driving an EV instead?
If you drive an electric vehicle, none of the prices on this page apply to your own fuel cost directly, since they cover gasoline and diesel rather than electricity. Use the EV versus gas comparator instead, which works in cost per mile using your own local electricity rate, or compare a specific EV's annual cost estimate against a gasoline vehicle's on the vehicle comparison pages.

Frequently asked questions
Four factors explain most of the difference: state and local fuel taxes, which can vary by fifty cents a gallon or more between states; special low-emission fuel blends some states and cities require, which cost more to refine; distance from refineries and major supply pipelines; and local competition and operating costs at the retail level. All four apply to varying degrees depending on whether you're looking at a national, regional, state, or city average.
PADD stands for Petroleum Administration for Defense District, a set of five geographic regions the US government defined during World War II to organize fuel supply and still uses today because the boundaries map closely to how gasoline actually moves through pipelines and refineries, which often explains regional price patterns better than state lines alone.
Premium has a higher octane rating, which takes extra refining steps to produce, and it's also a lower volume, higher margin product for retailers, both of which push its price above regular. The gap is fairly consistent nationally, typically 40 to 60 cents a gallon, even as the price of regular itself moves up and down.
The underlying data comes from the US Energy Information Administration's weekly retail gasoline and diesel survey, so this figure reflects roughly the last week rather than today specifically. Individual stations can and do move their posted price daily, so treat this as a reliable average rather than an exact quote from any one pump.
Diesel and gasoline are refined from the same crude oil but through different processes and are subject to different demand patterns, since diesel demand comes heavily from freight trucking and industrial use rather than passenger vehicles. Diesel also carries a slightly higher federal tax per gallon than gasoline in the US, which combined with refining and demand differences usually keeps its price a bit above regular gasoline, though the gap does shift with the seasons.
Large metro areas like Boston often diverge somewhat from their state's overall average, usually due to higher local real estate and delivery costs pushing prices up, partly offset by heavier competition among a larger number of stations. Check Massachusetts's own state-level page on this site for a direct comparison.
Two things happen at once heading into summer: many areas require refineries to switch to a cleaner, more expensive summer fuel blend meant to reduce smog, and vacation driving pushes demand higher at the same time. Both push prices up together, and both typically reverse after Labor Day when refineries switch back to cheaper winter-blend fuel and demand eases.
It reflects the most recent weekly EIA survey available for this region, generally accurate to within a normal week's price movement. For a large purchase decision or a trip departing very soon, checking a live price-comparison app for your exact route is worth the extra step, but for general trip budgeting this average is a solid starting point.
