??? that last answer makes no sense to me whatsoever. Ethenol is a better fuel in every respect than petrol - problem - it rots the rubber and plastc parts in the carburettor.
It IS true that ethenol has a (much) higher octane rating than standard grade petrol, it burns cooler than petrol (unless you increase the compression ratio to take advantage of the octane rating), so the valves will last forever.
In summary - don't use it unless you have no choice - it WILL cause problems with the carb, but if you don't mind rebuilding the carb every cauple of years, go ahead.
