Soob does specify 50 weight oil for this engine for heavy duty applications and it works a lot harder than it ever does in a car. My oil pan temp will get up to 120 C (250 F) on hot weather climbs and the 5W50 is also comfortable for sub freezing start ups. I only have about 65 hours on the engine since new but I'm aware of others that have run similar for a few hundred hours now.

I thought I had a problem with many of the symptoms some of you mentioned, then had that rascal prop balanced, and I really have trouble believing it is the same aircraft, it is sooo smooth, why didn't I have that done many hours ago...It cut the "worry factor" by at least 60%...........Hope I didn't insult anyone........................................CHEERS!!!!

Particularily aircraft standard spark plugs; seems a lead fouled plug makes a Lycoming so sick, it runs as if two cylinders went on vacation. With CDI's and auto plugs (why would anyone run mags and "those plug"), smooth is the operative word. :-))) Wayne ----- Original Message ----- From: Gene Smith To: engines-list Sent: Saturday, February 17, 2007 5:28 PM Subject: Engines-List: Engine Running Rough Please don't all of you shoot me at once................I have a suggestion for all of you who think your "rough" engine may be caused by internal problems...Before you spend a lot of time, labor, and money, I would install new spark plugs, new spark plug wires, and check the mags if you have mags...(I know almost all of you did this first, but maybe someone out there didn't?)...Above all, have a Pro. prop shop BALANCE your PROP while it is on the aircraft.
