I use full synthetic oil in my two stroke Seadoo watercraft. This oil leaves hardened carbon deposits on the top of the pistons and on the rave valves. I don't know if I would want this kind of buildup on my exhaust valves, manifold and turbo vanes.
I also use Optilube XPD in my 2004.5 5.9 which transforms the engine; smoother, quieter, and more power. You can definitely tell when the engine is running dry as opposed to with XPD. Those that don't use additives should run a couple of tanks with Optilube XPD. You will notice the difference. Optilube has a lubricant only product which Amazon shipped by mistake instead of XPD, not near as good. I prefer to use products formulated for the task at hand rather than anecdotal products.
