Gas Prices Remain Near 4-Year Low; Lowest in Oklahoma, Highest in California

The U.S. Energy Information Administration reported Tuesday that the national average price of regular gasoline is at its lowest level since spring 2021, settling at $2.90. Prices have remained below $3 per gallon for 11 consecutive weeks, the first such stretch since May 2021. State-level data from AAA shows Oklahoma with the cheapest average at about $2.50, followed by Arkansas, Kansas, and Mississippi. In contrast, California, Hawaii, and Washington are above $4 per gallon, with Oregon, Nevada, and Alaska also among the most expensive. Variations reflect differences in fuel taxes—over 17% of the price in late 2025—proximity to refineries and pipelines, and special fuel blends like California’s required cleaner-burning gasoline.
