Gas Pain, Week of October 26, 2026

The U.S. average for regular gasoline slipped 1¢ to $4.27 a gallon for the week of October 26, 2026. Over the past 12 weeks it was up $0.19, from $4.08 to $4.27.

California was the most expensive state at $5.89, $1.62 above the national figure, with Washington at $5.20 and Alaska at $4.87 (West Coast excl. California regional average) next. At the other end Texas was cheapest at $3.63, $0.64 below national, followed by New Mexico at $3.70 (Gulf Coast regional average) and Mississippi at $3.70 (Gulf Coast regional average). The gap between the priciest and cheapest state was $2.26 a gallon, which on a 15-gallon tank was $33.84 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 $0.33 to $4.38; Colorado (+$0.18) and Illinois (+$0.12) also rose. California fell the most, down $0.14 to $5.89; Alaska (−$0.14) and Arizona (−$0.14) also fell.

At the national average a 15-gallon tank cost $64.03 to fill from empty and a 26-gallon truck tank $110.99; think mid-size sedan and full-size pickup. That was $0.22 less than the week before on the smaller tank and $0.39 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.
