If cars could be 'tuned' optimally for ethanol fuels and nothing else, they would probably run great.
As it is, they now have to run on gasoline with a variety of fuel mixtures and oxygenation.

 

I don't think we will ever completely run out of petrol based fuel. However, the price will get so high that only a small percentage of the population can actually afford to operate a gas powered vehicle. Imagine having to go to Autozone to buy a couple of gallons of gas for you antique G35 and it costs about $50.00 to do so. Because of this, antique motorcycles will become more common than antique cars, and everyone driving their electric/hydrogen cars will frown at you as you go buy and pretend to cough at the "fumes". Liberal busy bodies will try to get all antique cars banned for health reasons. Eventually the gasoline vehicle will be forgotten by all but a few die hard collectors.

 

Here's your answer.

This thread makes my head hurt.....
Oil is not an infinite resource, it WILL run out. With that said, it sounds like a lot of you are falling for the Hollywood/ Al Gore propaganda. Gas is not the tool of the anti-christ. Maybe it is??
