Enjoy the recently slightly lower prices. When the refineries switch over from mostly gas/diesel/av gas to include heating oil, the reduction in gas (that's what they reduce mainly) production will drive the price right back up to 5 bucks a gallon. It's currently about $3.40 ish down from right at $5 weeks ago here in South Texas. My guess is it will bump off $3 in late August or early September before it starts back up towards $5 again,
On top of that, quite a bit of low-risk annual maintenance has been deferred over the summer, and the reduced refinery production levels resulting from those temporary shutdowns to do it now this fall will also increase prices. The only real hope, deeping recession, if that's what you want to call it, is that demand for non-fuel petro products drops due to reduced economic activity as well as demand for fuel products other than heating oil thereby adding production capacity to fuel production.
Refineries in the US are and have been running at flatout production levels most of this year. There simply isn't any refining headspace and if anything goes wrong like a hurricane in the gulf, refinery fire, extreme winter in the northeastern US, or any other unforeseen crude production reductions elsewhere in the world then all bets are off.
As the current recession lengthens and results in increases in unemployment, we may see lower demand for fuel products and that will also lower prices. People don't drive as much if they don't have a job to go to.
