Gas Pain, Week of August 11, 2025

The U.S. average for regular gasoline slipped 2¢ to $3.12 a gallon for the week of August 11, 2025. Over the past 12 weeks it was down $0.04, from $3.16 to $3.12.

Washington was the most expensive state at $4.31, $1.20 above the national figure, with California at $4.27 and Alaska at $3.78 (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 $2.68 (Gulf Coast regional average) and Mississippi at $2.68 (Gulf Coast regional average). The gap between the priciest and cheapest state was $1.66 a gallon, which on a 15-gallon tank was $24.95 for the same fill. The ranking counts all 50 states, with the regional average standing in wherever EIA publishes no state figure.

Washington climbed the most, up $0.04 to $4.31; Idaho (+$0.03) and Montana (+$0.03) also rose. Ohio fell the most, down $0.26 to $2.92; Texas (−$0.08) and Alabama (−$0.05) 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 $0.33 less than the week before on the smaller tank and $0.57 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.
