The U.S. average retail price for regular gasoline was $2.24/gallon (gal) on August 29, the lowest price on the Monday before Labor Day since 2004, and 27�/gal lower than the same time last year. Lower crude oil prices are the main factor behind falling U.S. gasoline prices. Lower crude oil prices reflect continued high global crude oil and petroleum product inventories and increased drilling activity in the United States.
