Gas Pain, Week of October 6, 2025

The U.S. average for regular gasoline edged up 1¢ to $3.12 a gallon for the week of October 6, 2025. Over the past 12 weeks it had finished exactly where it started.

California was the most expensive state at $4.45, $1.33 above the national figure, with Washington at $4.41 and Alaska at $3.98 (West Coast excl. California regional average) next. At the other end New Mexico was cheapest at $2.72 (Gulf Coast regional average), $0.41 below national, followed by Mississippi at $2.72 (Gulf Coast regional average) and Louisiana at $2.72 (Gulf Coast regional average). The gap between the priciest and cheapest state was $1.73 a gallon, which on a 15-gallon tank was $26.00 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 $0.14 to $2.99; Texas (+$0.08) and Florida (+$0.07) also rose. Colorado fell the most, down $0.09 to $2.83; Idaho (−$0.04) and Montana (−$0.04) also fell.

At the national average a 15-gallon tank cost $46.86 to fill from empty and a 26-gallon truck tank $81.22; think mid-size sedan and full-size pickup. That was $0.09 more than the week before on the smaller tank and $0.16 on the larger one. Of the ten states at the extremes, 8 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.
