Just to offer another opinion....
If your engine is a clone from Superior and ECI, it is approved for 91
mogas. I think just recently even Lycoming has approved mogas, but with
impractical caveats to keep with their longstanding CYA. No one approves
ethanol, though, AFAIK.
It doesn't make a lot of sense to me that Rotax prefers mogas over avgas for
their engines, not to mention all the auto engines, Subarus, etc. I am sure
their engine tolerances are a lot tighter than Lycoming. Also, have to
remember that if you run a fixed pitch prop that your manifold pressures are
less, especially if you have a climb prop.
I have run mogas most of the time in my Rebel. It still gets avgas from time
to time, when on trips, and when I broke in the engine. Also, during the
winter, I use avgas, as I don't fly as frequently then.
From the research I have done, and heard from long time users, is that mogas
makes for a cleaner engine, especially plugs, and you have less valve
sticking issues, resulting in fewer valve failures.

Hi Mike !
The 160 hp version is not suitable for mogas - that's one reason why
most
here prefer the 150 hp !
In Canada, Shell is the only company that has comitted to NOT use
ethanol in it's premium gas -- years ago, we found Shell Gold was the
best gas for the Rotax 912 -- I believe it still is !
In any case, with any new engine, you should run 100 LL for at least
a couple of hundred hours to let the lead soak into the metal for
lubrication ... or you could end up with "spot-welded" valve seats !

So can I use mogas with a lyco 0-320b2b-160 hp engine , perhaps the top
grade at Sunoco, and assume it must be erhanol free
Or should I stick to avgas
Cheers
