Valve floater;
What Jody from Valley View told you is absolutely correct. If you want to use a really great synt. oil use BelRay. Either the MC-1 or the HR-1. Both are pretty much the same in quality. The HR-1 can be mixed at 80:1, the MC-1 at 50:1. This oil will keep your motor shiny on the inside. No deposits, whatsoever.
