The average U.S. price of regular-grade gasoline jumped 5 cents a gallon (3.8 liters) over the past two weeks, to $2.97.

Industry analyst Trilby Lundberg of the Lundberg Survey says Sunday that gas prices have spiked 66 cents since early January.

But Lundberg says dropping crude oil costs could mean that prices at the pump will soon stabilize.
