“While the national average declined for the seventh straight week, with oil prices rallying, it remains to be seen if we will manage another week of gasoline price declines. We’re still waiting for the national average to fall below $3 per gallon, something that is suddenly a bit less likely given the extreme cold weather, interrupting refining operations in the south, curbing gasoline production and potentially driving prices up slightly,” said Patrick De Haan, head of petroleum analysis at GasBuddy.

“While some of the nation’s lowest priced gas stations will probably be forced to raise prices slightly, with some declines still happening in the West Coast, there remains a chance, albeit smaller one, that we could still see the national average fall below $3 per gallon,” he said. “With the New Year on the doorstep, however, the biggest question motorists have remains what will happen in 2023 – a question GasBuddy’s annual Fuel Outlook will answer later this week.”
