“Gasoline prices continue to crumble across nearly the entire nation, with average prices below $3 per gallon in 18 states, with some 65,000 stations selling below that psychological mark. Diesel prices are also falling and are at their lowest level in nearly 1,000 days,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “With the change to winter gasoline happening today at most stations across the country, the outlook is bright for the national average to continue to make a run at falling to $2.99 per gallon for the first time since 2021. But while nearly all states are seeing prices drop, refinery maintenance and some outages at California refineries have led to tight supply and rising prices—a situation I hope can be remedied by the end of the month and help California join in on the decline.”
