Hi folks,
One question that I have pondered; and still am not exactly sure of it this:
Full synthetic oil is the recommended oil for unleaded auto gas in the Rotax; and, a person cannot use full synthetic oil if leaded fuel is used, for the stated reasons. That all makes sense.
Now - what does a person do who burns mostly unleaded auto gas; but, may occasionally need to burn 100LL?
The rotax manual I have for the 912ULS says a person can run up to 25% leaded aviation fuel; but I don't remember seeing anything about what to do with the oil in this case.
In other words, is there anything wrong with running oil which is not fully synthetic all the time in the case that occasionally a person may end up using 100LL?
Sincerely,

BTW - at least for Minnesota folks, or those who visit here, there is a listing of all gas stations which sell unleaded 92 octane auto gas. This is located on the Minnesota Street Rod Association website as a 4 page PDF. The site is www.msra.com - then click on "Features" and you will see a selection for "non-oxygenated fuel". The car folks have issues with ethanol too (not too many jokes about that now! Although, I will mention that one corn gas refinery in Benson, MN also makes a high octane Vodka on the side.)
