What "problem" are you referring to? Ethanol is ethanol, regardless of the
feedstock used to make the ethanol. Polymers in the fuel system need to be
formulated to tolerate ethanol regardless of the feedstock.

Ethanol is an expensive waste whether you use corn or sugar cane. Even Al
Gore admits this now, revealing recently that he'd only pushed for fuel-
ethanol as a sop to farm states in the hopes of improving his chances at
the presidency.
