my 99 dosn't like the 10 percent, I pay the extra 5 to 10 cents for the real gas.. the power and milage make up for it.
I am sure that with a few changes my dodge truck would run fine on the alky... but btu's it will use more fuel.
it is just the power locked into the fuel.

on the other hand I would love to see, (after the motor is hot). one cycle of gas and one cycle of water, steam engine.
or with the computers now. fire ever other cylinder every other cycle with water, to use up the 80 percent or so heat that go's to waste. if you look it up there is the GUY of motors working on a 6 cycle motor. looks good to me. alot better then the big little motor that is out there.
the circle motor thing.
