Brockton Gas Ranges From $3.61 to $4.20; Diesel Near $5

Brockton drivers are seeing a wide spread at the pump, with verified station listings showing regular gasoline from $3.61 to $4.199 per gallon and diesel from $4.79 to $5.19 on August 4, 2026.

These are individual station prices, not a Brockton citywide average. The listings cover three Brockton stations and show why checking more than one location can matter for commuters, households and commercial drivers.

Regular gas ranges across 59 cents

The lowest verified regular-gas listing is $3.61 per gallon at Cumberland Farms, 1813 Main Street. The highest is $4.199 at 7-Eleven, 1234 Belmont Street. That is a difference of about 59 cents per gallon.

For a 15-gallon fill-up, that gap works out to roughly $8.84. A driver who buys 60 gallons over several weeks could see a difference of more than $35 by choosing the lower-priced listing instead of the higher one, assuming the prices remain unchanged.

Diesel listings span 40 cents

Diesel prices also vary by location. Cumberland Farms at 1813 Main Street lists diesel at $4.79 per gallon, while Cumberland Farms at 1205 Belmont Street lists diesel at $5.19. The verified spread is 40 cents per gallon.

That difference is especially relevant for delivery vans, work trucks, contractors, landscapers, service companies and other businesses that purchase fuel in larger quantities. A 30-gallon diesel fill-up would cost about $12 more at the higher listed price.

Massachusetts comparison

AAA’s August 4 Massachusetts price check lists the statewide regular-gas average at $4.112 per gallon, down from $4.122 the previous day. The statewide diesel average is $5.474, unchanged from the prior day.

The lowest verified Brockton regular-gas and diesel listings are below those Massachusetts averages. The 7-Eleven regular-gas listing is slightly above the statewide gasoline average, while both verified Brockton diesel listings are below the statewide diesel figure.

Compared with the last Brockton fuel-price check on July 31, the current Cumberland Farms listings are lower: regular gas at 1813 Main Street is listed at $3.61, compared with $4.099 in the earlier check, and diesel is listed at $4.79, compared with $5.399. The station set is not identical across every comparison, so those figures show movement at the verified listings rather than a citywide trend.

For Brockton households, comparing nearby stations before filling up could make a difference. The spread can affect weekly commuting costs, business operating expenses, restaurant and delivery pricing, and the cost of weekend travel.
