Hi,
Given the virtual unavailability of UL91, and thinking about the Rotax engine in particular,
is there any benefit in adding, say, 10-20% of 100LL Avgas to Mogas to overcome some of the known disadvantages of Mogas without triggering the additional oil changes necessary if one exceeds 30% 100LL?
