Questions people ask
What is the average gas price in Boston right now?
$4.33 a gallon for regular the week of October 5, 2026, down 1¢ from last week. Premium is $5.33. Diesel $6.48 (New England average). The number is the EIA's weekly retail average, updated every Monday.
Is gas in Boston higher than a year ago?
Yes, by $1.34 (45%) from a year ago: it was $3.00 this week last year.
Where does this number come from?
The U.S. Energy Information Administration surveys retail stations every Monday and publishes the average for each metro, state and region. PumpWatt shows the figure as published, with premium beside regular, and keeps every week on file.
What does a tank actually cost in Boston?
It depends on your car and where you fill up. The Fill up calculator starts from this week's Boston average and pulls your car's MPG from the EPA. Then it counts the cashback app, the card and the detour, so two stations with the same sign price can cost different amounts.
