Joe Sixpack’s sensitive to fuel prices after all. Or so one could argue given the latest batch of gasoline data from the Energy Information Administration. The most-recent weekly average for demand, through September 9, fell to 8.636 million barrels of gasoline a day. That’s down more than 4% from 9.027 million b/d in the previous week. The drop’s even steeper from the 9.406 million b/d of two weeks ago. Is this a sign that higher prices have triggered a new era of conservation-minded Americans when it comes to fuel? Or is the recent data an anomaly and/or a cyclical glitch tied to the end of the traditional driving season?
