“For the third straight week, the national average price of gasoline has fallen, once again setting a new multi-year low,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “Just ahead of Christmas, the national average stands at its lowest level since March 12, 2021, delivering weekly savings of nearly $400 million compared to this time last year. Gas prices are now lower in a majority of states, and the good news is that the downward trend may continue into the closing innings of 2025, with further declines likely across much of the country. That’s being driven by refineries wrapping up maintenance and boosting output to near summer highs, increasing fuel supply, while additional oil production from OPEC has pressured crude prices lower as well.”
