Not exactly ... The Ethanol itself will not (at least that is my
understanding), but the ethanol absorbs moisture and the moisture is
the enemy.
Not as big an issue with sealed (non-vented) fuel systems as used in
modern cars unlike older boats that have fuel systems vented to the
atmosphere.
To prevent problems, use a fuel stabilizer designed for Ethanol
blended fuels (Stabil now has a product such as this) and keep the
tank FULL when the car is going to sit for any period if time.
E10 fuel has a rather short shelf life, however it is only the portion
of fuel exposed to air that is a serious problem. So, by keeping the
tank topped off to the fill neck minimizes the amount of fuel exposed
to air.
Or, I could be completely wrong about everything :-)

Will ethanol corrode gas tanks? If so, how can one prevent it?
