Prices jumped nearly 11 cents over the past two weeks to $2.35 for a gallon of regular-grade gasoline, even though the price of crude oil dropped, a national survey said Sunday.
The hike obliterates the 9-cent drop that had begun January 20, said Trilby Lundberg, publisher of the Lundberg Survey.
"Those five weeks of declines were due largely to our being at the bottom of our gasoline-demand curve," she said.
Lundberg said an expected increased demand for gasoline in the spring and new government gasoline formulation requirements
conspired to drive up prices at the pump.
