Gas Pain, Week of September 29, 2025

Relief at the pump this week. The U.S. average for regular fell 6¢ to $3.12 a gallon for the week of September 29, 2025, the kind of drop that shows on the first fill of the week. Over the past 12 weeks it was down $0.01, from $3.13 to $3.12.

Washington was the most expensive state at $4.45, $1.33 above the national figure, with California at $4.45 and Alaska at $4.01 (West Coast excl. California regional average) next. At the other end Texas was cheapest at $2.65, $0.47 below national, followed by New Mexico at $2.67 (Gulf Coast regional average) and Mississippi at $2.67 (Gulf Coast regional average). The gap between the priciest and cheapest state was $1.80 a gallon, which on a 15-gallon tank was $27.03 for the same fill. The ranking counts all 50 states, with the regional average standing in wherever EIA publishes no state figure.

No state rose more than half a cent. Ohio fell the most, down $0.16 to $2.86; Colorado (−$0.14) and Florida (−$0.10) also fell.

At the national average a 15-gallon tank cost $46.77 to fill from empty and a 26-gallon truck tank $81.07; think mid-size sedan and full-size pickup. That was $0.83 less than the week before on the smaller tank and $1.43 on the larger one. 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.
