While national gasoline prices have increased one penny from one month ago after experiencing a spike over the long holiday weekend earlier in September, the state average has dropped two cents to $3.65 for a gallon of unleaded regular. Still, that places the state among the second highest priced states nationally as listed in AAA Auto Club’s Fuel Gauge Report. In Jackson Hole, meanwhile, the average of prices surveyed by Motor Trend is $3.92 per gallon — 3¢ higher than the average one month ago. The average in Teton Valley, Idaho is currently $3.77 per gallon. The Auto Club says gas prices for the remainder of the month remain uncertain due to escalating tensions in the Middle East and North Africa; but they could drop just as easily if the month remains relatively calm politically. Furthermore, the switchover to less-expensive winter-blend gasoline begins September 15th . AAA explains that over the past several months, gas stations have been required to sell more expensive summer-blend gasoline to meet air-quality regulations.
