U.S. gasoline prices at the pump are poised to drop by year end, if history is any guide, as refineries resume production, Europe exports more fuel to the East Coast and Americans drive less. Prices at service stations may fall about 6.3 percent to $3.54 a gallon, according to eight years of seasonal data compiled by Bloomberg. Gasoline deliveries to the U.S. from Europe may rise 35 percent, according to the median of eight estimates in a Bloomberg News survey. Demand has declined an average of 3.6 percent from July through December during the past five years, Energy Department data show.
