Gasoline Prices Increase: Prices at the pump were up a little more than 1 cent a gallon on average during the last three weeks, a national survey showed. The average price of gas on Friday was $1.1086 per gallon, including all grades and taxes, according to the Lundberg Survey of 10,000 stations nationwide. Survey publisher Trilby Lundberg said the upward trend started in January. The last survey, taken Jan. 21, showed an average price of $1.0985 cents per gallon, up from the Jan. 7 figure of $1.0951. The rise “should be looked at as a partial correction of extraordinarily low prices that prevailed from a fall oversupply of gas and a winter drop in crude oil prices,” Lundberg said. At self-serve pumps, the average price of regular unleaded gas was $1.0361; at full-serve pumps, regular unleaded was $1.4313 per gallon.
