Gas Pain, Week of June 30, 2025

Relief at the pump this week. The U.S. average for regular fell 5¢ to $3.16 a gallon for the week of June 30, 2025, the kind of drop that shows on the first fill of the week. Over the past 6 weeks it had finished exactly where it started.

California was the most expensive state at $4.36, $1.20 above the national figure, with Washington at $4.30 and Alaska at $3.83 (West Coast excl. California regional average) next. At the other end Texas was cheapest at $2.73, $0.44 below national, followed by New Mexico at $2.74 (Gulf Coast regional average) and Mississippi at $2.74 (Gulf Coast regional average). The gap between the priciest and cheapest state was $1.63 a gallon, which on a 15-gallon tank was $24.50 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 $0.03 to $3.08; Washington (+$0.01) also rose. Ohio fell the most, down $0.17 to $2.99; Florida (−$0.17) and Texas (−$0.13) also fell.

At the national average a 15-gallon tank cost $47.46 to fill from empty and a 26-gallon truck tank $82.26; think mid-size sedan and full-size pickup. That was $0.73 less than the week before on the smaller tank and $1.27 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.
