Well, actually, Bill after doing some "research" on the internet (not that volume makes correct) there seems to be quite a bit of "agreement" that the synthetics do not keep the things like Lead in suspension very well, permitting it to collect in areas. But, you point is well taken, not running out to change the oil this morning {:>)

Ed, So everbody will understand I have been concerned as well. There are some items I have read about that do present problems. More piston engine problems than rotary. 100 LL is really a misnomer, there is a large amount of lead in 100LL compared to say old leaded auto fuels. One of the problems listed was a "washdown" effect caused by the typee of use aircraft engines usually get. Hard use 80-100% followed by long periods of non use. Lead buildup caused problems on valve stems, plug fouling, etc. Of course the fact unmentioned was that the high lead levels in 100LL cause some valve sticking and plug fouling when used with petroleum based oils as well. Run your engine regularly and you should have few problems.
