Gas Pain, Week of July 13, 2026

Gas got noticeably more expensive. The U.S. average for regular jumped 8¢ in a week to $3.85 a gallon for the week of July 13, 2026. Over the past 12 weeks it was down $0.27, from $4.12 to $3.85.

California was the most expensive state at $5.20, $1.35 above the national figure, with Washington at $4.85 and Alaska at $4.39 (West Coast excl. California regional average) next. At the other end Texas was cheapest at $3.37, $0.48 below national, followed by New Mexico at $3.42 (Gulf Coast regional average) and Mississippi at $3.42 (Gulf Coast regional average). The gap between the priciest and cheapest state was $1.83 a gallon, which on a 15-gallon tank was $27.44 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 $0.23 to $3.80; Colorado (+$0.21) and Idaho (+$0.16) also rose. Washington fell the most, down $0.05 to $4.85; Alaska (−$0.03) and Arizona (−$0.03) also fell.

At the national average a 15-gallon tank cost $57.83 to fill from empty and a 26-gallon truck tank $100.23; think mid-size sedan and full-size pickup. That was $1.17 more than the week before on the smaller tank and $2.03 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.
