Domestic crude oil closed above $67 a barrel Thursday for the first time since September on continuing concerns that the refining industry is not producing enough gasoline to meet summer driving demand.

That worry, which drove gas prices at the pump to record levels last month, was exacerbated by Wednesday’s government report that showed refinery utilization fell last week, and that gasoline inventories did not grow.

Light, sweet crude for July delivery rose $1.39 to settle at $67.65 a barrel on the New York Mercantile Exchange. That was the front month contract’s highest close since Sept. 5, when it settled at $68.60.
