Apparently there is 110 varieties of gasoline in this country

And more are being created, additives right now do add to the cost of gasoline but they make the Gas burn much cleaner. Nano-Catalyst's can theoretically be very cheap and make a good catalyst. This price shock could be a very good thing indeed, it will force people to adapt and in turn that will change the economy and hopefully steer it away from Oil dependancy. It's just insane to have a infrastructure setup with so much fragility built into the system! More unstable then a tripod...
