Retail gasoline prices continued to fall.

Price wars have appeared in a few cities, oil industry analyst Dan Lundberg said. “There’s no general retail gasoline price war going on in America, but there are almost a dozen cities in . . . the markets we survey in all 50 states that show exceptional below cost gas price competition,” he noted. Lundberg, publisher of an industry newsletter, surveys retail gasoline prices around the nation every two weeks. The latest survey showed the average price at self-serve pumps of leaded regular at 90.13 cents, regular unleaded at 96.63 cents and premium unleaded at $1.125. The national average for all grades of gasoline was $1.0374, down more than 7 cents a gallon since Feb. 21. In Denver, Lundberg found one station selling regular at 62.9 cents a gallon.
