Dan,
Your message quotes someone who says

I’d not use alcohol containing fuel
in a Coupe without determining it’s safe – that that’d be a
fairly high hurdle.
First, you’d have to confirm that
there’s no sloshing compound. Simple auto fuel can attack aviation
sloshing compounds. (I’ve heard a fuel tank person say that our Coupes
are not really allowed to have sloshing compound. He said the tanks should be
sealed without any sloshing compound. I have no personal knowledge of the
legality.)
Next, you’d have to check all the
non-metallic portions of the fuel system from the fuel lines to the varnish on
the cork fuel gauges to the diaphragm in the fuel pump for alcohol
compatibility.
You can easily test for alcohol and, if
you search, maybe you’ll be able to find some sources of non-alcohol. If
it’s really not available, I’d stay with the “high-priced
spread” for the foreseeable future.
(Note: a technical discussion like this
is appropriate for the TECH group but let’s not move it now.)
