I might have tried those other additives, but the only one that has worked is Tufoil. I can remember my 98 Dodge Ram that had the legendary knocking. For those of you who don't know what I'm talking about, the knocking literally sounded like 2 sledge hammers hitting each other at full force. Dodge said that there was no damage being done. Shortly before I won my lemon law suit, I put in Tufoil, and amazingly, it solved the problem, made the truck run smoother and MPG went up.
