| The adding of ethanol to gasoline has made the auto-gas
STC unusable
| for many aircraft owners, nationwide. So far, we're
okay (in Iowa,
| which is pretty funny) and are able to purchase
untainted mogas -- but
| the long-range situation seems untenable. We, as a
nation, are
| inexorably being forced toward the addition of alcohol
into ALL
| gasoline, so it seems...
|
| On the Cherokee 235 user's group, there is a guy who's
been
| successfully using ethanol-gas in his aircraft. It's
ruined his
| fiberglass tip tanks, but he apparently expected this to
happen.
| Otherwise, the engine is running fine, or so he reports.
(Personally,
| I think he's crazy, ruining tip tanks that run close to
$4K *apiece*,
| but that's just me...)
|
| His experience has led to a more interesting (to me)
discussion about
| the possibility of REMOVING ethanol from gasoline.
Several ideas have
| been postulated (evaporation; heating; adding water),
but none of them
| sound particularly safe or easy.
|
| Any chemists out there? Anyone know a way to remove the
ethanol from
| mogas, so that we may safely use it in our aircraft?

| This was discussed a while back. While I'm not a chemist I
would think that
| what came out of the removal process would have a
completely unknown octane
| rating that would probably be lower than what went in.
|
| I also think "successfully using ethanol-gas" and "ruined
his fiberglass tip
| tanks" really shouldn't be used in the same paragraph.
