This youtube video is what started my research on butanol years ago. However, it wasn't until much later when I realized that normal n-butanol was too low in octane number for me to use in my V8. The only saving grace was stumbling upon GEVO with their "iso-butanol" which has a higher octane content, perfect for my V8 and perfect to increase compression ratio! A cleaner burning fuel with better combustion efficiency will yield better fuel economy when the motor is tuned appropriately for these changes.

From what I learned, Ethanol requires modifications to the motor to allow 100% use whereas Butanol does not require such extreme modifications albeit a minor change to the air-to-fuel ratio but as a stand-alone pump fuel to mix with gasoline, you won't have problems using it in an unmodified gasoline motor.
