This is on the long side so bear with me.
Are you talking about oil or gasoline prices, I know gas is cheaper but i though crude was holdign steady. keep in makd that teh pump to pump life for oil or teh time it takes for it to be pumped, shiped refined shipped again and pumped in to your car is something lke 6-8 weeks. Gas prices spiked because of seveal reasons:
1) A bad winter created a lot of demand for heating oil, so when refinaries were suposed to be making summer gas, they still were makign heatilng oil, reserves never were able to be built up
2) To meny belnds needed in teh summer, There are something like 20 diernt blends needed aroudn this nation and 3 grades in each blend, soa total of like 60+ types of gas are needed in this country. Why so meny? The EPA mandates that areas that have pollution problams fix them before they can get more federal funding for certian projects, these areas are called non-atianment zone, each zone has a differnt problam, and one wy theis problam is solev is to mandate a special blmed of gas. teh troube it that this gas can only be used in that area, and no other, and no other type of gas can be used in that area, so a small number of refinaries are providing gs to an area, and if tehre is a problam at the refinary or in teh piplines used by it to suply teh gas, other types of gas can not be used in teh special blends place, supply droppes, prives rise.
Thsi could be solved if teh EPA would pick a few blends of gas and allow severa areas to use each blend, more refinaries would be making each blend s a problam at one rfinary would not be so much of an issue.
3) WAY more cars on the road, and lower average millage. you can tell tis by drving, there are alot more cars out there, and a lot of tehm are SUV's and minivans, which do not get good millage. over the past few years, teh average millage of all consumer cars sold has gone down, so we have more cars using more gas per mile and to top it off, people are diving more,
This is a simple answer to this quesion, I am a transportation geography stuuden so i have studied this a lot, and some of teh numbers i have seen scare me.
back to teh gs/oil price issue, keep inmind that most of teh oil we (the U.S.) imports, comes from venesula and a couple of other central and south american nations, nto teh middle east
