Gas Pain, Week of July 27, 2026

Gas got noticeably more expensive. The U.S. average for regular jumped 9¢ in a week to $4.10 a gallon for the week of July 27, 2026. Over the past 12 weeks it was down $0.40, from $4.50 to $4.10.

California was the most expensive state at $5.49, $1.39 above the national figure, with Washington at $5.01 and Alaska at $4.66 (West Coast excl. California regional average) next. At the other end Texas was cheapest at $3.64, $0.45 below national, followed by New Mexico at $3.69 (Gulf Coast regional average) and Mississippi at $3.69 (Gulf Coast regional average). The gap between the priciest and cheapest state was $1.84 a gallon, which on a 15-gallon tank was $27.67 for the same fill. The ranking counts all 50 states, with the regional average standing in wherever EIA publishes no state figure.

Minnesota climbed the most, up $0.19 to $4.04; California (+$0.13) and Idaho (+$0.13) also rose. Ohio fell the most, down $0.01 to $3.85.

At the national average a 15-gallon tank cost $61.44 to fill from empty and a 26-gallon truck tank $106.50; think mid-size sedan and full-size pickup. That was $1.42 more than the week before on the smaller tank and $2.47 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.
