Hello all,
All this Ford Spec talk has me thinking. I have 2 more oil changes with Mobil Delvac 5w-40 CJ-4. Ford has not listed them meeting the new spec. I called Mobil Delvac and the person reluctantly told me they would expect Zinc levels at around 1,300 and Phosphorus levels around 1,100. I obviously purchased this oil before the Ford drama emerged. The UOAs I have posted seem to look good. Should I be worried and run something more specifically green lighted by Ford (CK-4 or CJ-4). Appreciate the help.
