Everything you might want to know about mogas can be found in this Chevron
technical review ;
http://www.chevronwithtechron.com/products/documents/69083_motorgas_tech_rev
iew.pdf Your specific question is discussed on page 45 of that document.
The answer to your question about "normal auto fuel" seems to be: maybe J
Be sure to read the final paragraph on page 94, where Chevron tries to scare
us into not using mogas in aircraft engines.

<mailto:j_l_walsh@yahoo.com> j_l_walsh@yahoo.com>
I run ethanol free mogas in my 912 (Diamond Katana) currently. I noticed in
my AFM that Diamond allows fuel that meets the ATSM D4814 fuel standard as
well as 100LL. I believe this standard allows up to 10% ethanol but the
ATSM website charges $60 for the pdf file. Does anyone know if I am correct
and that normal auto fuel pump gas is ATSM D4814 compliant. This would let
me buy some of my fuel at my local gas station. Thanks for any help. -John

ASTM is okay with auto fuel. As an example many of the SLSA aircraft are ASTM compliant
and allowed to use auto fuel. ASTM isn't the same nor have the teeth
that the FAR's do.

Thanks for the link, I'll read it in a bit.
Diamond Aircraft changed the language in the AFM for my Katana regarding fuel specification.
If the fuel meets ASTM D4814 it is allowable which is great because
ethanol free gasoline is hard to find. I'm lucky that there are 2-3 airports
within 50nm that sell it. I understand that Rotax allows up to 10% ethanol.
