Gas Pain, Week of December 8, 2025

The U.S. average for regular gasoline slipped 4¢ to $2.94 a gallon for the week of December 8, 2025. Over the past 12 weeks it was down $0.23, from $3.17 to $2.94.

California was the most expensive state at $4.27, $1.33 above the national figure, with Washington at $3.98 and Alaska at $3.61 (West Coast excl. California regional average) next. At the other end Colorado was cheapest at $2.32, $0.62 below national, followed by Texas at $2.46 and New Mexico at $2.49 (Gulf Coast regional average). The gap between the priciest and cheapest state was $1.95 a gallon, which on a 15-gallon tank was $29.31 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 $0.07 to $2.65. Idaho fell the most, down $0.14 to $2.64; Montana (−$0.14) and Utah (−$0.14) also fell.

At the national average a 15-gallon tank cost $44.10 to fill from empty and a 26-gallon truck tank $76.44; think mid-size sedan and full-size pickup. That was $0.67 less than the week before on the smaller tank and $1.17 on the larger one. Of the ten states at the extremes, 6 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.
