What Is Phase Separation?

[@BenKlassen1]

Another reason why ethanol has no place in the fuel for our vehicles. Another dumb idea forced upon the public.

Ethanol raises / increases the octane rating of raw gasoline, thus it is necessary, the problem with ethanol is the it separates from gasoline as water. Therefore, an engine needs the higher octane but is adversely affected when ethanol breaks down. If you do not let fuel sit in storage, you will not have an issue.
