Ethanol is so widely available in fuel now that a large share of "normal" gasoline is really "E10".
Even if the fuel system was compatable with E85, it would not work well. E85 has a very different air/fuel ratio. It must run much richer than gasoline. Unless you have the equipment onboard to measure the actual alcohol content and alter the air/fuel mixture accordingly, it will run way too lean. Not only will it run very badly if at all, it would be so lean that you could damage the engine.
