How much ethanol (percentage wise) can you put in a tank of gasoline without affecting the performance of a gas powered automobile?

Every vehicle in the US can burn 100% ethanol. I saw a study of over 450 non flex-fuel vehicles driven for 10 years on 85% or higher ethanol and the engines were actually better than straight gasoline.

The prescribed amount for most automobiles is 10% by most manufactures. However did you know that when you burn ethanol you produce CO2?
C2H5-OH+O2 = CO2+H2O(vapour) both CO2 and H2O(vapour) are greenhouse gasses
In Australia 10% ethanol blend is known as E10. It costs the same as regular petrol and delivers less power and has a lower fuel economy so you end up using more per kilometre.
Good luck convincing me to use it.

My auto manual says 10%. In fact most gas these days contains 10% ethanol, at least in California.

I have to agree with Professor Kitty! Oh, and one other thing you might want to check your manual for - many engines aren't designed to tolerate even the 10% addtion of ethanol. It will eventually destroy many of the rubber seals and gaskets if the engine wasn't designed to use this fuel type. Another case of caveat emptor LOL.

In Brazil they tune the cars so they can burn higher percentage of ethanol. I don't know how they do it but if it works for them I suppose it could work for gringos.
