My experience with it is some batches created a black tar like substance at the injector tip that was easily cleaned off. Even my 1994 Honda fuel system handles it (albeit with upgraded pump and injectors to keep up with fueling demands). And it sits up to 6 months at a time.
Ethanol is Hygroscopic, it attracts and holds onto moisture, which is far more prevalent on coastal and lake regions, and can cause major damage to engines. Obviously, cars are less likely to have moisture in the fuel lines, but its not impossible.
Seals in general, unless silicon based, get destroyed by Ethanol. Alcohol turns plastics and rubber brittle. That is the primary problem.

NOW HEAR THIS, NOW HEAR THIS... a few years back the EPA gwarranteed the no manufacturer could sell equipment susceptible to ethanol fuel degradation. (not a joke).
In a parallel universe my tractor friends have told me that townships of 5K and lower can still sell ethanol free fuel. and that an online ( I think) listing is available. I have not pursued. Repair facilities still report swollen viton carb parts and heavy deposit which clog fuel systems, but that may be on
?pre 98? stuff.
A gallon of ethanol gas can absorb about 4 teaspoons of water. Beyond that the water and some ethanol ride along with the mixed fuel as fellow travellers which the EPA admits can affect idle. See Wikepedia for more reading pleasure.
