“With the conclusion of the summer driving season, we can expect gasoline prices to go on a diet," Senior Petroleum Analyst Patrick DeHaan said in a release. "Like all diet programs, you may not see immediate loss in the short term, but we'll likely see some loss in the longer term, say the next several weeks, as factors align in motorists’ favor. Specifically as Isaac has exited without much ado, demand to see seasonal decline, and with cheaper-to-produce winter-spec higher RVP gasoline coming, there's light at the end of the tunnel.”
