Hartford Gas Eases to $4.171 as Diesel Rises to $5.559

Regular gasoline in the Hartford metro averaged $4.171 per gallon in AAA’s August 4, 2026, check, while diesel averaged $5.559. The fuels moved in different directions: regular gas fell from the prior day and week, while diesel rose.

Regular gas moves lower

AAA’s Hartford metro figures put regular gasoline 1.3 cents below the previous day and 2.3 cents below a week earlier. The latest average was still 30.9 cents higher than a month ago and $1.060 higher than a year ago.

That means the small short-term decline has not erased the larger increase facing commuters and households that rely on gasoline for work, school, errands and weekend travel.

Diesel rises while staying above $5.55

Diesel averaged $5.559 per gallon in the same Hartford-area check. That was 1.6 cents higher than the previous day and 3.7 cents higher than a week earlier.

Diesel was also 33.2 cents above its month-ago average and $1.771 above its year-ago level. Those increases can affect fuel budgets for contractors, delivery operators, landscapers, service businesses and restaurants that depend on commercial vehicles or fuel-consuming equipment.

Hartford compared with Connecticut and the U.S.

For context, AAA listed Connecticut’s regular-gas average at $4.191 per gallon on August 4, compared with a national average of $4.089. Hartford’s regular-gas metro average was below the statewide figure but above the national comparison.

These are metro and statewide averages, not guaranteed prices at every Hartford-area station. Individual pumps may be higher or lower depending on location, competition, taxes, traffic patterns and whether a station is near a highway.

Commuters and households may want to compare stations before filling up. High-mileage drivers and commercial operators should also plan around the larger month-to-month and year-over-year increases rather than relying on the latest daily movement.
