Gas Pain, Week of January 5, 2026

The U.S. average for regular gasoline slipped 2¢ to $2.80 a gallon for the week of January 5, 2026. Over the past 12 weeks it was down $0.22, from $3.02 to $2.80.

California was the most expensive state at $4.03, $1.24 above the national figure, with Washington at $3.71 and Alaska at $3.34 (West Coast excl. California regional average) next. At the other end Colorado was cheapest at $2.19, $0.61 below national, followed by Texas at $2.32 and New Mexico at $2.37 (Gulf Coast regional average). The gap between the priciest and cheapest state was $1.85 a gallon, which on a 15-gallon tank was $27.69 for the same fill. The ranking counts all 50 states, with the regional average standing in wherever EIA publishes no state figure.

Florida climbed the most, up $0.06 to $2.75; Georgia (+$0.01) and North Carolina (+$0.01) also rose. Ohio fell the most, down $0.18 to $2.54; Washington (−$0.06) and Alaska (−$0.04) also fell.

At the national average a 15-gallon tank cost $41.94 to fill from empty and a 26-gallon truck tank $72.70; think mid-size sedan and full-size pickup. That was $0.23 less than the week before on the smaller tank and $0.39 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.
