Pennsylvania Gas Prices This Week

In the EIA’s July 2026 (revised August 2026) table of motor fuel taxes, Pennsylvania’s state taxes and fees on gasoline total 58.7¢ a gallon, the 5th-highest of the 50 states and D.C. The 51-jurisdiction average is 33.8¢, and the federal tax adds 18.4¢ everywhere. Nearly all of it is the oil company franchise tax. Act 89 of 2013 abolished the separate liquid fuels tax and raised the fixed wholesale price on which the franchise tax is calculated, with the rate reset each year from average wholesale prices. For 2026 it is 57.6¢ a gallon for gasoline.

Pennsylvania still refines gasoline, though less than it did. The EIA’s January 2026 survey lists three refineries: Monroe Energy in Trainer (190,000 barrels a day), United Refining in Warren (67,000), and American Refining Group in Bradford (11,000). The Philadelphia Energy Solutions refinery, the largest on the East Coast, closed after a fire in June 2019. The Laurel Pipeline carries products west from the Philadelphia area toward Pittsburgh. Federal reformulated gasoline is required in the five Philadelphia-area counties: Bucks, Chester, Delaware, Montgomery, and Philadelphia.

In the EIA’s annual state series, Pennsylvania has moved from below the national average to above it. Its average gap was 1.9¢ below the U.S. figure in the 1980s, then 3.9¢ above in the 1990s, 3.2¢ above in the 2000s, 11.0¢ above in the 2010s, and 12.1¢ above in 2020–2024. It ranked 14th-cheapest of 51 in 1980 and 43rd in 2024. The highest annual average is $4.04, in 2022, 14.4¢ above the U.S. average; adjusted for inflation the peak was 2012, at $5.17 in 2025 dollars. The series also shows the 1986 oil price collapse: Pennsylvania’s average fell 27.4% that year, close to its largest decline, in 2015 (27.6%).

Pennsylvania has no weekly EIA series. The weekly Central Atlantic region (PADD 1B) shows the seasonal pattern: averaged over 2004–2025, 7.2% below the year’s average in January and 5.3% above in June.

Pennsylvania's most favourable position in the EIA annual series was 4th-cheapest in 1982, the same year its average sat 4.4¢ below the U.S. figure, the largest amount below in any year from 1970 to 2024. Its least favourable position was 43rd-cheapest, or 9th-most-expensive, in 2017 and again in 2024. In 2014 the average stood 14.9¢ above the U.S. figure, the largest amount above in any year.

Between those points the rank moved from 32nd-cheapest in 1970 to 24th-cheapest in 1990, 26th-cheapest in 2000 and 34th-cheapest in 2010. In 2020 it was 40th-cheapest, at $2.31. Pennsylvania averaged below the U.S. in 11 of 55 years, among them 1973, 1978–1982, 1986–1989 and 2001, and above it in 43 of 55 years.

The 2024 average was $3.40, which is $3.49 in constant 2025 dollars. Compared with bordering states that year, Pennsylvania was 23.0¢ above New York at $3.17, 19.4¢ above New Jersey at $3.20 and 15.0¢ above Ohio at $3.25. All 6 of 6 bordering states averaged less than Pennsylvania in 2024.

One-year moves in the annual average include a rise of 45.2% in 1974. The lowest inflation-adjusted average was $2.14 in 1998. From 2014 to 2024 the average fell 1.8% at the pump and fell 25.9% in constant 2025 dollars. The EIA estimates each year after 2010 from the change in the state's region, so the year-to-year moves since 2011 are the region's moves.
