I am a dedicated E10 user in my a/c, but just had a nasty experience in my
auto,
My auto is fitted for LPG and uses gasoline only for a few seconds at start.
This has resulted in the same E10 in the gasoline tank for a long time
(probably 2 years), The result - heavy rusting, failed pumps (one in the
tank and one in the fuel line), clogged filters.
So this is a clear example of one of the downsides to this E10, You need to
keep turning it over, keep tanks full, etc. to stop any effect of the
absorption of water from the air.
My a/c has aluminum tanks, two in-line filters which I watch and change, and
I check the carb bowls every 50 hours. Also never any vapor lock, up to
9500ft (I haven;t cruised higher)

Hi,
I'm new to this list, but know of two guys (snowbirds) on our airpark in
Florida that drain their tanks and run a limited amount of 100LL through
their 912s for summer storage (5-6 months). They claim 100LL will not
deteriorate the fuel system as with the autofuel they normally use. Seems
to work.

Thanks for all the tips on printing this manual. I will do something soon.

Put 100LL in a sealed drum and you can count on it remaining stable for 2
years. Do the same for mogas and it will start to degrade in 2 months. The
key here is SEALED, i.e. no vents. Add venting and mogas starts to
deteriorate in days.
I've not tried Sta-bil for ethanol adulterated gas but the regular grade
works great for non ethanol grade.

JMO, but my tactic is to simply consider leaving E10 sitting the plane to be not
good period. What I do during the down periods (spring, summer) is drain the
tank after about a week and half or so. If it's going to be sitting longer than
that I'll drain completely and refill with 100LL. I'll run the motor a bit
to get the E10 out of the float bowls and lines also.
I've found 100LL keeps a lot better when sitting that autogas. And I wouldn't like
E10 to sit for any period of time at all due to moisture retention, etc.
