Motorists concerned about the rising price of gasoline can brace for another jolt when they get ready to winterize their autos.
The Persian Gulf crisis is one of the reasons, a major antifreeze marketer said Monday.
"Chemicals needed to produce antifreeze . . . are in tight domestic supply," said Michael Barcum of Old World Automotive. "Supplies of naphtha are expected to decrease even further because supply ships cannot pass through the Persian Gulf."
He said prices may go up within the next 30 days.
