Ethanol fuel especially the 10% has been out on market for years here and is actually mandated by the EPA here. It does get a lot bad things said about it. Personally I have use it well over 20 yrs now in all my equipment without most of the problems a lot of poster say they have. The only real problem I have seen with it is that is must be kept in tightly seal containers or it absorb moisture from the air which settles out as water with the alcohol mixed in it. It just like the rubbing alcohol contains up to 70% water and doesn't separate.
I do however use a fuel stabilizer if I am going to store long term (IE over 30 days and up to 2 years).
Some the problem users claim to be the result of using it I see with pure fuel. Now it does affect some rubbers that are not design to handle it but small engine manufactures are making their equipment to be able handle 10% Ethanol fuel now days. What a lot users don't understand or know there is a lot other additives in fuel in to meet EPA standards and they are also causing problems here. They are even using Ether @ 15% here in place of the Ethanol.
