I'm no expert on this, but I've read that pure ethanol is very aggressive on aluminum and other alloys, while even just 1 % of water would stop that, and a higher water content could even de-oxidize it (iirc).
The effect is the same in ethanol/gasoline blends, as the gasoline is pretty much inert to the alloy.
We're talking about a 85% gas / 14.4% ethanol / 0.6% water mixture over here. So 15% of 'wet' ethanol.
It is hard to find anything on the subject that's not written in Dutch, but
here goes. To make matters worse, HE.15 happens to be some kind of aluminum alloy code.
