Gas Pain, Week of October 20, 2025

The U.S. average for regular gasoline slipped 4¢ to $3.02 a gallon for the week of October 20, 2025. Over the past 12 weeks it was down $0.12, from $3.14 to $3.02.

California was the most expensive state at $4.43, $1.41 above the national figure, with Washington at $4.30 and Alaska at $3.88 (West Coast excl. California regional average) next. At the other end Texas was cheapest at $2.51, $0.51 below national, followed by New Mexico at $2.56 (Gulf Coast regional average) and Mississippi at $2.56 (Gulf Coast regional average). The gap between the priciest and cheapest state was $1.92 a gallon, which on a 15-gallon tank was $28.73 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 $0.29 to $3.01. Texas fell the most, down $0.07 to $2.51; Alaska (−$0.07) and Arizona (−$0.07) also fell.

At the national average a 15-gallon tank cost $45.29 to fill from empty and a 26-gallon truck tank $78.49; think mid-size sedan and full-size pickup. That was $0.63 less than the week before on the smaller tank and $1.09 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.
