First generation non-VVT had a reputation for valve seats falling out and broken exhaust manifold bolts (last one primarily on truck engines).
VVT Hemi (this one) has, over time, developed a reputation for failed cams, lifters, and timing chains.
Pick your poison
Whether these are a vendor or parts quality problem, or a maintenance problem or what, I just don't know.
You should be able to download the owner's manual from FCA or Dodge's website. Look for a specialized "pursuit" manual first
and see if you can find anything there. If not, the the regular owners manual will tell the tale.
Certain early non-vvt models specified mobil 1 10w30 per an owners manual addendum, but that was before FCA jumped into bed with
SOPUS (pennzoil), and being out of the loop since 2013 I'm not sure if any different recommendations exist for pursuit models anymore.
If you get a healthy one, and get an oil analysis or two, you will see that they are usually pretty forgiving and easy on oil. Other than MDS system
functionality they don't seem to be very picky.
