Boston Gas Prices Reach $4.154; Diesel Holds at $5.433

Boston-area regular gasoline reached $4.154 per gallon in AAA’s July 28 metro price snapshot, while diesel stood at $5.433. Both fuels were more expensive than a week earlier, although diesel edged lower from the previous day.

AAA’s Boston metro table listed regular gasoline at $4.154 per gallon, up from $4.075 a week earlier and $3.957 a month earlier. The figure is a metro average, not a guaranteed price at every station.

Gasoline is higher on both weekly and monthly comparisons

Station prices can vary by neighborhood, operator, payment method and proximity to major commuter routes. Drivers should treat the AAA figure as a benchmark for the Boston area rather than a promise of what they will see on a particular pump.

The U.S. Energy Information Administration reported a separate Boston regular-gasoline benchmark of $4.099 for the week ending July 27, compared with $3.992 for the week ending July 20. The EIA and AAA figures should not be combined as if they were readings from the same system. They use different collection methods and timing, but both show gasoline moving higher over the latest weekly comparison.

Diesel remains above $5.40

AAA listed Boston-area diesel at $5.433 per gallon on July 28. That was slightly below the previous day’s $5.457, but higher than $5.312 a week earlier and $5.189 a month earlier.

The one-day decline does not erase the broader increase. For delivery operators, contractors, landscapers, service businesses and other companies that use diesel vehicles, the weekly and monthly comparisons point to continued fuel-cost pressure. Higher diesel costs can also add to transportation expenses for goods and supplies, although the available data does not show whether Boston businesses have changed their rates.

What the move means for Boston drivers

For commuters, the most immediate effect is a higher cost for filling a gasoline-powered vehicle. Households planning weekend travel may want to compare stations before buying, especially because metro averages do not apply uniformly across the Boston area.

Restaurants that rely on delivery, contractors traveling between jobs and small businesses operating vans or trucks may also be watching gasoline and diesel costs closely. The price data alone does not establish how those businesses will respond, but sustained increases can make mileage and delivery expenses more significant in operating budgets.

AAA’s figures are updated more frequently, while the next EIA release is scheduled for August 4, 2026. Until then, the latest benchmarks show Boston gasoline higher than last week and diesel still above $5.40 despite a small one-day easing.
