The price of gasoline at the pump has barely increased over the past three weeks despite the new nickel-a-gallon federal tax, an industry analyst says.

The average price of a gallon of gas was $1.4606 on Dec. 7, up .08 cents from Nov. 16, according to Trilby Lundberg's national survey of 13,600 gasoline stations.Lundberg noted Sunday that prices did not jump despite the 5-cent tax imposed Dec. 1. "Crude oil prices have been softening for several weeks; therefore, gas suppliers were passing through lower crude oil costs," she said.

She also cited lessening fear of war in the Persian Gulf, reports of increased oil supply, lower demand for gas at this time of year and price competition between gas stations.
