Here is something I came across which caught my attention since I normally use 100LL av gas and may interest some of the rest of you.
I am looking for other sources to see if there is a general consensus about use of 100% synthetic oil and 100LL or rather against it.
I am currently using Mobile 1 as my break in oil

Hi Ed,
The article summarizes pretty well the stuff I've heard & read about pure synthetics in piston a/c engines using 100LL. Were you using Mobil 1 before your incident? If so, did you see any evidence of the lead buildup when you did your teardown?

(sorry that I forgot to make the connection between your use of Mobil 1 & avgas & mention it to you)
No, Charlie, actually I was using a different Exxon synthetic. But, no, not any sign of lead build up. Perhaps without valves to catch the lead and with less access of oil to the combustion area perhaps? the rotary is less susceptible to the problem. However, having found that Mobile is being sued due to damaged aircraft engines from folks who used their aviation synthetic, I may have to reconsider.
