After a sharp increase in the price of a gallon of gasoline late last month, the prices have remained steady in Jackson Hole. However, the national average has been decreasing over the past two weeks, dropping nearly five cents in that time to $3.71 per gallon. That’s according to the US Energy Information Administration. AAA Auto Club reports that the nation’s lowest average is once again in Wyoming, where the state average stands at $3.31 per gallon of unleaded regular. Here in Jackson, Motor Trend reports prices averaging $3.39 per gallon while Teton Valley prices average 3.474. AAA says the recent national decline is partially due to cheaper crude oil, but is most closely linked to tumbling wholesale gasoline prices. AAA goes on that the crude oil prices, which had drifted higher but traded in a narrow range to begin 2013, moved lower last week as increased crude oil inventories and bearish economic news weighed on markets.
