According to Eric Tucker and Rotax, there are two primary problems with using 100LL in the 912 and both can be dealt with.
1) If the engine is not primarily run on 100LL (up to 30% of time during oil change cycle) change oil and filter at 50 hours. Refer to Line maintenance manual 05-20-00 2.2.7) a) and b) note 1.
Greater than 30% of time during oil change cycle, change the oil and filter at 25 hours regardless of oil type. SI-912-016 3.3) page 4
In addition, when using 100LL, semi synthetic oil is recommended. Refer to SI-912-016, page 4.
2) If you run 100LL more than 30% an inspection of the overload clutches at 600 hours. Line maintenance manual 05-20-00, 2.2.5) b), page 8, and 05-50-00, 2.2), page 3. and SB-912-033.
