Yep.
Some friends of mine have run Amsoil 5W30 with no problems.

Shell 100W Plus is the only way to fly... 15W50 Syn does absolutely nothing for you... well, I take that back, it will take more money out of your wallet!!
Friends don't let friends use synthetic for aviation. At least, not in Lycs burning 100LL. Maybe in a Subie burning Premium.

So have any of you fellas switched to AMSOIL yet? In case you don't know, it is an ashless/dispersent oil - same as all other aviation oil. So yes - it does keep the lead in suspension.
As for costing you more, remember the change interval is at least 2 what std oils recommend, and yes I did run out to a 140hr change to see if anything happened. NADA, and the re-builder wanted to know why the case/cam/rods/under side of the pistons etc were so clean when he opened 'er up.
AMSOIL break-in oil has a big dose of zinc - better to help the cam and other sliding surfaces break in with no problems. Our aircraft engines needs zinc anyway - it's not like a modern auto engine that has all that stuff in the exhaust pathway that gets plugged up by a big dose of zinc...
Again - you don't need the full oil change to be AMSOIL - about 25% will do it. I would use regular intervals if mixed that way.
You mean, like, Mobil 1? And when you say "successfully", do you mean "no serious engine damage " or "no catastrophic engine failure"?Does anyone use synthetic oil in there Lyc's successfully?
