Recently my gas station placed stickers on the pumps warning it could
contain up to 10%% ethanol.
My ride is an experimental built in 1997 with a C-85 always run on mogas.
Quick research indicates 3 concerns:
1-loosens debris inside the fuel system affecting filters.
2-mixes more readily with water (hydroscopic) but can experience "phase
separation" during climbs causing water to overload filter/sediment bowls.
3-can deteriorate composites, rubbers and plastics causing leaks/breakages.
Leaning towards more frequent gascolator inspections for 1 and 3, but
unsure on overloading a sediment bowl....
I'm wondering how others are addressing these concerns.
Thanks, Dick

"Dick" ...
THis subject has been covered north, south, east, west, up, down, port, and
starboard in these newsgroups over the last two years. Please do your
research and investigation into prior threads before starting a new one.
Most folks who have posted good stuff just shine on somebody that isn't
willing to do the work before asking a very old question.

What's the harm. It's not like the daily message count is difficult to
manage.
You never can tell when there might be some new thinking or information, and
you won't find that in the archives.

Jim,
What's the problem?? I did do some net research but couldn't get any
download this morning from the EAA site for whatever reason and apparently
made the mistake to ask here what others are doing.
Sorry,

Phase seperation is when you add water to the gas / ethanol mix and the
ethanol / water seperates out. The ammount of water required to do this
depends on the ethanol concentration and the temperature - so things might
be OK on the ground where it's warm...
The water / ethanol mix will be too "lean" for you engine and the gasoline
left behind will have a lower octane than the gasoline / ethanol blend that
may or may not be adequate for your needs.
