As it stands now, the recent oil-price slump has brought the national average for a gallon of unleaded gasoline down to $2.59, according to the AAA motor club. In the Seattle area, prices per gallon have fallen to $2.856 currently from $3.071 a month ago, a decline of 7 percent, according to AAA.
Should oil traders fear that this downward price spiral will get worse and run for the exits by selling off their futures contracts, Verleger said, it's not unthinkable that oil prices could return to $15 or less a barrel, at least temporarily. That could mean gasoline prices as low as $1.15 per gallon. as per Drudge Report
