Ethanol is creating big problems in the gasoline powered boat world. Per an article in Boat/US magazine there are 2 problems with it:
1. Ethanol absorbs moisture from the air, ethanol is a solvent, and boat fuel systems must be vented. The ethanol is dissolving fuel varnish and other gunk in tanks and when combined with H2O it absorbs from the air forms a gelatinous gunk which clogs filters and fuel systems.
and the biggie:
2. Many high-end boats ( Bertrams and Hatteras' in particular)built in the 1960's thru 1990's were built with fiberglass fuel tanks. Many of these boats are considered classics and are still very valuable. The ethanol is dissolving the resin in these tanks and the resin / gasoline mixture is destroying very expensive engines as well as causing the fuel tanks to eventually weep gasoline (very bad news in a boat).
These particuclar issues may or may not ever apply to cars but ethanol has the potential to cause a lot of problems.
