Also, I imagine that if you tried to buy gas out of that pump (100oct Race Fuel) then they would tell you it has to go into a container (or a boat), and that you cannot pump it direct into your car.

There was a run of "exotic fuels" a few years ago in the motorcycle race circuits and the popular stuff was ELF. It was rated at about 105oct, cost about $40/gal, but it was something other than "gasoline", (there is a test for specific gravity,and if the "fuel" passes, you can run), and if you got near an open container it made you feel really sick, BUT it resulted in a few horsepower (in built motors - stock motors just ran "crisper", possibly better throttle response but no real increase in power).
