My dealer is a Chrysler/Ford dealership. I've been doing free changes that came as part of my purchase of 2016 Ram. I was filing the paperwork and 1st. 2 changes were PYB 5w-20. The last 2 were XO5w-20QSP which is Motorcraft semi blend and does not meet Chrysler MS-6395. I am not concerned about the oil as I think it's a very good oil, but if I had done this and had an issue it could be grounds to deny warranty as owners manual clearly states only MS-6395 oil should be used.
I've used up my free changes and will be using PP. I think I'm going to keep quiet and if something does go wrong, I'll drag out the paperwork.
