Don't know if it is appropriate for aviation use, but the gummy brown
crap can be minimized by the appropriate fuel treatment. I use heet (for
auto fuels with ethanol), Stabil for my yard equipment, and Sea Foam for
anything that is going to see minimal use over time. Usually use all

It would be that simple if you mentioned "ceteris paribus." You did not.
The human body is about 20% energy efficient. An old simple internal
combustion engine is about the same.
A well-tuned ethanol engine is over 40% efficient. A modern flex fuel
engine has a range of efficiency. And as the rep

I have a little knowledge of the benefits of ethanol in automotive
engines, but a newb with aviation engines. So please inform me on the
differences with aviation engines.
I have learned that not only flex fuel vehicles, but the supermajority of
the existing fleet of America's vehicles achieve opt

In theory, if you have a fuel with gas/ethanol and add water to it,

Larry;
Let's look at the "chemical" end of this question.
1) Water and alcohol are fully miscible: what this means is that these
molecules have such a strong affinity for each other that they "bind"
together with a strong enough bond that they will not naturally separate
