With the summer tourist season just around the corner, it appears summer gasoline prices across the nation will average about six cents lower than they did last summer. According to the US Energy Information Administration, U.S. consumers are expected to pay an average $3.63 a gallon during the heavily traveled summer driving season that runs from April through September. The EIA says the cheaper motor fuel reflects lower crude oil prices, which account for about 65% of what drivers pay at the pump. The agency points out that gasoline prices vary by state and region and may be higher or lower than the national average. The west coast typically sees some of the highest prices in the country while the Rocky Mountain States typically are on the lower end.
