CAMARILLO, Calif. (AP) — The average U.S. price of regular-grade gasoline fell 3 cents over past two weeks, to $3.46 per gallon. Industry analyst Trilby Lundberg of the Lundberg Survey says Sunday that the price drop is partly because of a crash in crude oil costs. It’s the first decline in gas prices in 14 weeks. The average price at the pump is $1.24 higher than it was one year ago. Nationwide, the highest average price for regular-grade gas is in the San Francisco Bay Area, at $4.80 per gallon. The lowest average is in Houston, at $2.91 per gallon.
