Unleaded Premium Fuel use in Ximango - Jul 2006

like auto fuel because the engine runs much smoother on it, it's at
least $1 per gallon cheaper, and 100ll has way too much lead in it
(fouls plugs, rings, and valves)=2E
what does everyone think=3F  Can I safely run high test unleaded with
up to 10% ethanol in this engine=3F

Now that all the filling stations in my area
(Baltimore/Washington)are blending up to 10% ethanol in all grades of
unleaded fuel as a replacement for MTBE as an oxygenate to cut
pollution, I will be forced to use this blend if I want to continue
to run auto fuel in my 912S (100 hp) engine=2E

I like auto fuel because the engine runs much smoother on it, it's at
least $1 per gallon cheaper, and 100ll has way too much lead in it
(fouls plugs, rings, and valves)=2E

Also, on the fuel cap issue:  The fuel caps delivered with the
Ximango(newer style)are manufactured by ACS Products Company in Lake
Havasu City, Arizona and are listed as part number 10450 on the
manufacturers production drawings=2E  They also manufacture a newer
style cap (marketed by Aircraft Spruce) listed as part number 10460
as a direct replacement cap for folks who burn automotive fuel=2E  This
cap has the Viton "o" ring seal that does not swell with auto fuel
use=2E The Xiamngo factory drills the unvented ACS caps with a 5/64"
vent hole in both the top of the cap and the round metal piece on the
bottom of the cap=2E  The 10460 cap also needs this same size vent hole
drilled in both pieces=2E  I would to suggest the Ximango factory
consider this direct replacement cap as a better alternative to the
older styled ones, which are quite a pain if you burn auto fuel=2E

All our advice and information is that Ximango owners should avoid ethanol 
in any form (including drinking it!) and use 100LL instead, the fuel that the 
plane is certified to use in the USA.

The rotax 912 is used in many m/gliders and whilst I do not use the mogas in my ximango I have been led to believe the main concern is that the factory fuel tanks were not correctly laid up and the mo gas woud eat into the fibreglass. In recent years the factroy has installed aloy tanks. If anyone can confrirm that Mo gas will NOT damage the tanks it might put a different inflection on the use of mogas.
