    In another forum, an owner of a Charger with a 3.5 engine reported major engine wear using expensive Royal Purple oil (see oil analysis, below). Has anyone encountered a similar problem? I'll stick with Mobil 1.

    That is the second article I have seen that says Royal Purple products aren't holding up. I always thought they were the best out there. Starting to change my mind.
