It does seem to beat up the oil a bit--at least it gets darker much quicker than in my other car with a hemi. A little disconcerting was this summer I noticed the water temp getting up to 235, which made me think something wasn't working right. But apparently this is normal for these engines and they're meant to run this way.
I can't speak for the 200c because I haven't driven one with the PentaStar in it but in the Caravans and Jeeps they are pretty easy on the oil, my father in law is doing 30K oci's yearly with his on Amsoil. (18K miles). The UOA seems fine with remaining TBN and reasonable TAN numbers.
They do run hot, their thermostat opens at 203F, that said mine in traffic will regularly get up to 220F before the fan kicks on high and brings it down. 235F seems a little high though so I would keep an eye on it. Maybe a wonky temperature sensor or sticking thermostat?
