Gas Pain, Week of March 30, 2026

The U.S. average for regular gasoline edged up 3¢ to $3.99 a gallon for the week of March 30, 2026. Over the past 12 weeks it was up $1.21, from $2.78 to $3.99.

California was the most expensive state at $5.71, $1.72 above the national figure, with Washington at $5.19 and Alaska at $4.88 (West Coast excl. California regional average) next. At the other end Minnesota was cheapest at $3.42, $0.57 below national, followed by Texas at $3.57 and New Mexico at $3.59 (Gulf Coast regional average). The gap between the priciest and cheapest state was $2.29 a gallon, which on a 15-gallon tank was $34.38 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 $0.10 to $3.83; Alaska (+$0.08) and Arizona (+$0.08) also rose. Colorado fell the most, down $0.10 to $3.76; Texas (−$0.03) and Alabama (−$0.01) also fell.

At the national average a 15-gallon tank cost $59.85 to fill from empty and a 26-gallon truck tank $103.74; think mid-size sedan and full-size pickup. That was $0.44 more than the week before on the smaller tank and $0.75 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.
