    It can't hurt to try. I have seen many posts which state a particular oil or oil type made the difference in "lifter" noise.

    It is a well known problem w/ the 3.6 cause right after I bought mine my father-in-law who has been a Chrysler mechanic since the late 60's told me that starting in 2011 they have had an issue where the manifold that is now part of head is to close and overheats the head. The problem is only on the passenger side. I have a 2013 w/ just over 70k and already had to have the head fixed cause after coming back from a trip it also had the dreaded lifter knock.

    Not really. The exhaust headers are cast into the head as one peice. Many manufacturers are doing this for lighter weight, and longevity.
