 Just read an article in the April Boating magazine, seems that GulfRacingFuels has developed an alternative to using ethanol as a gas additive, isobutanol. According to the article, this stuff is made from the same plant as is to make ethanol. It also doesn't have the corrosive qualities of ethanol, AND it provides greater performance and fuel mileage. The magazine actually tested the stuff itself in an older and newer boat to prove Gulfs claims. Right now, it's sold at marinas, hopefully it'll find it's way to the motorcycling community

interesting. It would be great to get rid of ethanol in the normal fuel supply. 

Any idea about octane or resistance to detonation?

Sounds interesting.  Google Isobutanol and you can read ALL DAY but the Gulf Racing Fuels web site is most informative and kind of related to bikes.  

DOWN WITH ETHANOL!

 The fuel Boating Mag used was 93octane, the article was short, it didn't mention resistance to detonation

True although the higher octane rating mix had a higher percentage so it must help with detonation.

If it is a derivative of the same plant then it is still organic.  I can tell you from the amount of carbs I've rebuilt over the last year(including a 600cfm Edelbrock last night) that the ethanol in gas not only drags water through your system, but the organic part causes algae growth.  Buy ethanol free if you can.
