I'm just not sure its credible, though, since its one of those "this is what a Zerex guy told me" type posts:

Yeah, that is a big nut to swallow on internet hearsay. I have followed this whole FCA OAT coolant thing for awhile now with having owned a 2014 Jeep Wrangler and now a 2015 RAM and the wife's 2013 FIAT calling this OAT coolant out.
The problem is finding coolant branding/manufacturing documentation stating "top off" mix compatibility with the factory stuff and not a full flush and fill replacement suitable substitute that some coolant makers claim which is a different thing all together.
I have read and seen the horror stories of getting this wrong on mixing other types with the factory OAT stuff and it just has never turned out good.
