Gas Pain, Week of August 3, 2026

The U.S. average for regular gasoline slipped 2¢ to $4.08 a gallon for the week of August 3, 2026. Over the past 12 weeks it was down $0.41, from $4.49 to $4.08.

California was the most expensive state at $5.50, $1.42 above the national figure, with Washington at $5.04 and Alaska at $4.68 (West Coast excl. California regional average) next. At the other end Texas was cheapest at $3.53, $0.55 below national, followed by New Mexico at $3.60 (Gulf Coast regional average) and Mississippi at $3.60 (Gulf Coast regional average). The gap between the priciest and cheapest state was $1.96 a gallon, which on a 15-gallon tank was $29.45 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 $0.24 to $4.08; Idaho (+$0.06) and Montana (+$0.06) also rose. Florida fell the most, down $0.15 to $3.77; Texas (−$0.11) and Minnesota (−$0.10) also fell.

At the national average a 15-gallon tank cost $61.18 to fill from empty and a 26-gallon truck tank $106.05; think mid-size sedan and full-size pickup. That was $0.26 less than the week before on the smaller tank and $0.44 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.
