 See, contrary to popular opinion, I like oil analysis. I just don't like to do it every oil change. I don't think that's necessary because there's not much I can do about it. But if I've got an engine noise, if I've got something going on, I'm glad to do an oil analysis then because what's it going to come back and tell me? It's going to come back and tell me, do they see bearing material? Do they see anything? Is it clean?
