Gas Pain, Week of August 24, 2026

The U.S. average for regular gasoline edged up 4¢ to $4.08 a gallon for the week of August 24, 2026. Over the past 12 weeks it was down $0.06, from $4.15 to $4.08.

California was the most expensive state at $5.45, $1.37 above the national figure, with Washington at $5.21 and Alaska at $4.78 (West Coast excl. California regional average) next. At the other end Texas was cheapest at $3.58, $0.50 below national, followed by New Mexico at $3.64 (Gulf Coast regional average) and Mississippi at $3.64 (Gulf Coast regional average). The gap between the priciest and cheapest state was $1.87 a gallon, which on a 15-gallon tank was $28.04 for the same fill. The ranking counts all 50 states, with the regional average standing in wherever EIA publishes no state figure.

Colorado climbed the most, up $0.13 to $4.38; Minnesota (+$0.12) and Washington (+$0.09) also rose. Ohio fell the most, down $0.20 to $3.98; Texas (−$0.04) also fell.

At the national average a 15-gallon tank cost $61.27 to fill from empty and a 26-gallon truck tank $106.21; think mid-size sedan and full-size pickup. That was $0.54 more than the week before on the smaller tank and $0.94 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.
