like I said initially, ethanol with water, ethanol or ethanol with methanol will work. I bet E85 would work if the pump and all the other components could handle the petroleum and additives, but that would be even more rich than straight ethanol, and probably wouldn't work as well as ethanol or methanol.
at this point, I just want to understand why methanol works better.
on a different topic, I did see one article in which Ford was running a dual injection of pump gas and E85. it was on an ecoboost vehicle, and the regular gas was used for the fuel economy, and while in boost, the E85 was injected to suppress any predetonation.
