"A string of planned and unplanned refinery maintenance issues has severely tightened fuel supply in California," said Doug Shupe, the Automobile Club of Southern California's corporate communications manager. "West Coast fuel inventories are at the lowest level in about a decade according to Energy Information Administration.
"Until the refineries are fully operational again, supply is going to be tight and will cause pump prices to be volatile."
There may be "some relief" in November when stations are again allowed to sell winter-blend gas which is cheaper to produce, Shupe told City News Service.
