As I recall Rotax recommends using a high quality, major brand, 4-stroke motorcycle oil with gear additives and (SF) or (SG) API classification.

The gear additives are required to withstand the high stresses in the reduction gearbox. The (GL4) or (GL5) specification is recommended.

Full synthetic is not recommended if you are running 100LL more than 30% of the time.

I recommend consulting a qualified Rotax mechanic who probably has a better memory than I and is familiar with your particular aircraft.
 
Vance, your information is a bit out of date; Rotax worked with Shell to develop a new oil they recommend for all of their 4-stroke engines, which as Will said is called Aeroshell Sport Plus 4. It is now the ONLY oil that Rotax recommends.
 
Yep...Aeroshell Sport Plus 4.
 
So no one is using any other kind of oil but Aeroshell sport pluse 4?
 
I use it because they say to but it looks like something I would put in a wore out Harley.
