Mike, somehow I never saw that but even if it exists and I am not aware of it I am willing to top it up and trade it off for the benefit of avoiding the weekly annoying lifter issue. I simply feel the lifter problem can cause more damage to my old engine than whatever can hurt it by topping it up to the max point. I think you have a set of very healthy (young) lifters in your engine. When they get old and you hear the noise once every week or more you will want a remedy to cure it. You will want it badly. You will probably not care if topping oil up will do anything otherwise to your engine. Yes, it is a remedy for old and tired engine, not a suggestion for everyone. David
