2016 Sorento SXL-Turbo
If you go by what a lab says and you have a warranty issue your going to have a problem proving you followed recommended OCI. Good synthetic oil is cheap and not following what Kia recommends could cost you big time. Good luck.Yeah no I know about turbos and gdi killing oil. But you gotta remember we’re all running synthetic. Only way to truly know is to get you oil analyzed. It will tell you how much life your oil has left in it. I do know that VW/Audi and I think BMW say 10K mile OCI on full syn. If they can do 10k you should get more than 3 out of it.
