Gas Pain, Week of June 15, 2026

Relief at the pump this week. The U.S. average for regular fell 9¢ to $4.05 a gallon for the week of June 15, 2026, the kind of drop that shows on the first fill of the week. Over the past 12 weeks it was up $0.06, from $3.99 to $4.05.

California was the most expensive state at $5.55, $1.50 above the national figure, with Washington at $5.34 and Alaska at $4.84 (West Coast excl. California regional average) next. At the other end Texas was cheapest at $3.43, $0.62 below national, followed by New Mexico at $3.52 (Gulf Coast regional average) and Mississippi at $3.52 (Gulf Coast regional average). The gap between the priciest and cheapest state was $2.12 a gallon, which on a 15-gallon tank was $31.83 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 $0.06 to $4.08; Florida (+$0.04) also rose. California fell the most, down $0.14 to $5.55; Connecticut (−$0.14) and Maine (−$0.14) also fell.

At the national average a 15-gallon tank cost $60.78 to fill from empty and a 26-gallon truck tank $105.35; think mid-size sedan and full-size pickup. That was $1.41 less than the week before on the smaller tank and $2.44 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.
