I think most of the concern about ethanol is misplaced, or at least =
exaggerated.
One, who still has 50-year-old rubber parts in their engine? These =
expendable components have all been replaced multiple times at this =
point, and all the replacement hoses have been ethanol-compatible for a =
decade at least.
Two, all California fuel has contained ethanol for a long time. That=E2=80=
=99s a test involving 40 million vehicles, and probably one million =
vintage and antique vehicles, including my stable of 2 or 3. I have =
never noticed any bad effects from fuels containing up to 10% ethanol.
It seems to me that the people who are always warning about the =
=E2=80=9Cdangers=E2=80=9D of ethanol are the same people who never use =
it; that is, that have no personal experience.

That's obviously too far.
