Pittsburgh Gas Rises Again While Diesel Holds Above $5.50

Regular gasoline rose again in the Pittsburgh metro on Friday, July 31, while diesel remained above $5.50 per gallon. AAA’s July 31 Pittsburgh metro price check listed regular gas at $4.288 per gallon and diesel at $5.521.

These are Pittsburgh metro averages, not guaranteed prices at every station in the city or Allegheny County. They reflect the July 31 price date and should not be read as live station prices for Saturday, August 1.

Regular gas moves higher

Regular gasoline increased 1.9 cents from the previous day, when the Pittsburgh metro average was $4.269. It was also 1.5 cents higher than a week earlier, when AAA listed the average at $4.273.

The shorter-term increase came even as the monthly comparison remained lower. Friday’s regular-gas average was 9.1 cents below the month-ago average of $4.379.

Year over year, however, the cost remained substantially higher. The July 31 average was 93.4 cents above the year-ago average of $3.354.

Diesel stays above $5.50

Diesel followed a separate upward path. The Pittsburgh metro average rose 0.5 cents from the previous day, moving up from $5.516, and increased 2.3 cents from a week earlier, when it averaged $5.498.

Diesel was 3.4 cents below its month-ago average of $5.555. But it was still $1.432 higher than the year-ago average of $4.089, keeping the fuel well above last summer’s level.

The U.S. Energy Information Administration’s latest gasoline and diesel update, released July 28, listed July 27 averages of $4.096 per gallon for regular gasoline nationally and $5.313 for on-highway diesel. The East Coast averages were $3.997 for gasoline and $5.354 for diesel. Those figures provide broader context but do not replace AAA’s Pittsburgh-specific averages.

What higher fuel costs can mean locally

For Pittsburgh commuters, even small daily changes can add up across repeated trips to work, school, child care, appointments and errands. The year-over-year gap is more significant for households that drive long distances or rely on larger vehicles.

Diesel prices also matter for contractors, delivery operators, landscapers, utility crews and other service businesses that use trucks or equipment. Higher fuel costs can add pressure to operating budgets and may become one factor businesses consider when setting estimates, delivery charges or service-area limits. Restaurants and retailers can also face indirect transportation costs as goods move through regional supply chains.

Weekend travelers should keep in mind that the metro average can hide substantial differences between individual stations. Checking several locations before filling up may produce a lower price than the area average, particularly for drivers willing to travel a short distance.
