Audi,
I'm not advocating that Seafoam is a miracle product or won't hurt your engine if uses improperly. Nor am I vouching for blindly following such a procedure as adding it to your crank after putting in fresh oil. Heck I wouldn't do that in a million years. Just because they recommend it, you can't go to them and say this messed up my engine because I followed your instructions. I know other people that swear by Lucas oil treatment too, so for better or for worse people will use what they know to be right.
I'm hardly an expert so please, for the sake of yourself and your cars please always do your own careful investigation, care and due diligence in matters such as these.
Thanks again for all of the helpful advice.
