Gas Pain, Week of September 22, 2025

The U.S. average for regular gasoline held at $3.17 a gallon for the week of September 22, 2025, unchanged from the week before to the cent. Over the past 12 weeks it was up $0.05, from $3.13 to $3.17.

Washington was the most expensive state at $4.51, $1.34 above the national figure, with California at $4.47 and Alaska at $4.06 (West Coast excl. California regional average) next. At the other end Texas was cheapest at $2.69, $0.48 below national, followed by New Mexico at $2.72 (Gulf Coast regional average) and Mississippi at $2.72 (Gulf Coast regional average). The gap between the priciest and cheapest state was $1.82 a gallon, which on a 15-gallon tank was $27.30 for the same fill. The ranking counts all 50 states, with the regional average standing in wherever EIA publishes no state figure.

Ohio climbed the most, up $0.18 to $3.02; Florida (+$0.04) and Minnesota (+$0.04) also rose. Texas fell the most, down $0.08 to $2.69; Alabama (−$0.06) and Arkansas (−$0.06) also fell.

At the national average a 15-gallon tank cost $47.59 to fill from empty and a 26-gallon truck tank $82.50; think mid-size sedan and full-size pickup. Of the ten states at the extremes, 7 were shown at a regional average, because EIA publishes a weekly state figure for only 9 states and the rest take the average of their PADD region. Every figure here was from EIA's weekly retail gasoline series for that week.
