“Even with oil prices jumping more than $4 per barrel compared to last week, the national average price of gasoline has resumed its decline as refineries wrap up seasonal maintenance and prepare to boost output,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “Forty states have seen average gasoline prices fall over the last week, while just 10 have seen increases - most notably on the West Coast, where another refinery fire in Northern California once again disrupted gasoline production. As we approach Memorial Day, gas prices may see some minor fluctuations, but for now, I don’t expect any significant changes to the national average, with prices staying near their lowest seasonal level since 2021.”
