I'm sure everybody has heard all the stories about high mileage carburators and the oil companies etc. But why has this problem not been solved? Approximately two thirds of the fuel we burn in our cars goes out the tail pipe. I've read that someone has used catalytic cracking to breakdown the fuel into a more user friendly vapor and got incredible mileage. Naturally I'm a bit of a sceptic but I'd like to hear what people have to say about the idea.
