Back in the 70's? when the BIG 3 started exporting cars to Brazil, there were articles in car mags about the changes necessary to run on ethanol. Carbs, elastomer parts, mild steel fuel lines & tanks were among the items that would be eaten/softened/hardened corroded by ethanol. They all had to be different materials on those exports.

That makes me think back to my Model Airplane days.
We used silicone rubber tubing with methanol fuel
and IIRC, some rubber like neoprene for gas/diesel.
It seems one or the other, but not both. I got a
float needle for a bike carb that was tipped with
something $pecial. Just thinkin out loud.
Researching the history a little deeper it looks like this is a warranty (e.g. liability) issue with the OEM's. They aren't saying it will cause damage only that they are not willing to warrant the fuel for use in anything other than flex-fuel vehicles which have been designed for very high concentrations of alcohol. They will not warrant it in their regular 2001 - 2011 vehicles and want more testing at teh 15% level before they will. The EPA and fuel producers say the current testing of E15 in non flex-fuel vehicles is more than sufficient and has OK'ed the fuel for use in all 2001 and newer vehicles. The OEM's then went to court to try and block EPA approval of the sale of E15 and lost.
In any event the vast majority of states still don't allow it to be sold and in those that do E10 is still available right along side E15 and E85. If you don't own a flex-fuel vehicle and it worries you stick with the E10. I'm guessing in 10 more years when the warranty issue is moot the OEM's will suddenly decide that E15 is OK in all 2001 or newer vehicles just like the EPA and producers did. :roll:
