Part of the problem, but nobody wants to hear it, is you get about 45% gasoline and about 22. 5% diesel from a barrel of oil. Check out this link
http://www.eia. doe.gov/neic/infosheets/crudeproduction.htmAnother part of the problem happens to be the tighter environmental regulations. While I agree the changes they've made in diesel fuel haven't given us any advantages or improvements in mileage or engine longevity, the environmental nuts have decreed we must clean it up, therefore private industry does not get a choice in the matter, and must comply with the regulations. Who do you think ultimately eats the cost for such "improvements"? If you said "Consumers", buy yourself a cigar, you're a winner. The Government is part of the problem already. They tax fuel excessively, they decree certain specifications that must be met, and so forth. As bad as it may be now, it will end up worse if the Government gets involved.
Anybody remember what happened in the 80's and 90's when the fuel company profits dropped? Anyone? Beuller? Well here's what happened in a nutshell: Refineries closed, wells were capped, and it more or less set us up for the situation we're in now, which is not being able to keep up with demand as effectively as should be possible. So basically if the Government caps the prices, consumers will consume more (I know I'll drive a lot more, at $1. 50/gallon than I will at $2. 50/gallon). If you can't see where I'm going with that, there may not be hope. Combine that with the fact it's unlikely to push new refineries past both the NIMBY idiots and the environmental extremist idiots, and the situation isn't all that likely to improve very quickly. That's just the harsh reality of things IMO. Above all keep in mind the only thing the Government is good at is red tape, and you *will* be paying for their fuel industry services you want, probably more at the pump and more in your income taxes, etc. There is no free lunch unfortunately.
