AAA: Pump Prices Rise Slightly After Southern California Refinery Fire

WALNUT CREEK, Calif. – As autumn sets in, the national average price for a gallon of regular gasoline has dropped to $3.11 from last week’s $3.15 average.

According to the Energy Information Administration, demand for gasoline has fallen to a four-month low, contributing to the continued decline in pump prices. With the third quarter of 2025 ending in higher gasoline inventories and the seasonal transition from summer-grade to winter-grade fuel, consumers are likely to see even lower prices at the pump in the coming weeks.

Northern California refineries are expected to help cover supply in Southern California following the Chevron refinery fire in El Segundo late last week. The average cost of regular gasoline in California rose two cents per gallon since last week to $4.66.

“Events that slow or stop gasoline production can prompt increased bidding for available gasoline supplies,” said Doug Johnson, spokesperson for AAA Mountain West Group. “Pipeline disruptions, planned or unplanned refinery maintenance or refinery shutdown may cause prices to increase especially the longer they remain offline. However, there is good news around the corner. California switches to the cheaper winter-grade fuel starting November 1.”
