Frank; As John stated, AvBlend is a personal preference but I think it's more of an additional lubricant utilized where the oil migrates than anything else. Some years ago I bought and used a few cans, but not since. If it were my engine, I would try MMO in the fuel but would never recommend anyone else do it and would actually call you foolish if you did. If you plan on trying such as foolish thing, it would be best to stick to the recommendations on the can and if you found, by some miracle, that it helped, keep it under your hat as you would not want to recommend such an unapproved thing to another pilot.

He also mentioned something that could be put in the oil as well. I remember someone talking about an approved additive for oil to help deal with lead. Does anyone know what that might be?

An exchange cylinder, with piston rings is about $250 so let the guy make a few bucks. When you do an exchange, you must send the piston and when you o/h a cylinder it only makes sense to send the piston along.
