Hugh and gang, with only 50 hrs on our Allegro, we don't have much of a
track record but we elected to use the oil formulated specifically for the 912
engine and gear box and sold by California Power Systems. I think they call it
(AV9). It is a semi synthetic and fits our flying personality as we burn auto
and av gas.

Hugh,
The Rotax Owners website http://www.rotax-owner.com/ has a
comprehensive on-line library of service documentation for Rotax
engines. Among the hundreds of documents is one or more about proper
oils for the 912 series engines. There are three main things Rotax is
concerned about in oil for the 912 series engines.
1) The oil must have Gear Additives because the prop speed reducing
gear box uses the same oil as the engine. Because many 4 stroke
motorcycles have a similar arrangement some of the oils made for them
are suitable for the 912 series engines.
2) The oil must NOT have Friction Modifiers because the gear box has a
clutch.
3) If using 100LL Avgas more 30% of the time or more, the oil must NOT
be 100% synthetic because of the lead in Avgas.
I've been using a semi-synthetic oil sold by California Power Systems
designed specifically for the Rotax called AV-9 but will be switching
to Pennzoil Motorcycle oil w/ gear addititives(semi-synthetic) as soon
as my current case is used up. The AV-9 if fine oil but the shipping
cost from California is over $30 and I can get the Pennzoil from a
local distributer at about the same cost w/o the shipping charge. I
know some Rotax owners use a Fram equivalent oil filter (don't recall
the number) but I always buy Rotax brand filter. That is one thing I do
not want to gamble with. Also, I use semi-synthetic because we do fly
x-country sometimes where autogas in not available and in my opinion,
with any use of 100LL at all, the semi-synthetic is better.
You might want to consider subscribing to the Matronics Rotax Engine
list.
Attached is a list of Rotax approved oils I got from one of their
service bulletins.
