Just curious if any ck owners have looked at the maintenance schedule in the owners manual? When looking at the section for engine oil and filter, it is very vague and open to different interpretations. I can’t recall what the book said for my 2016, but I don’t remember it being confusing like this could be.
Looking at the schedule it could be interpreted that only the direct/indirect injection engines need oil change at 50 hrs, tier 2 or 3 at 200hrs, and tier 4 at 400. I suspect this is incorrect but will be contacting the dealership early next week when the owner returns from vacation.
