This is the longest OCI I've ever done on any of my cars (it is what it is), and it certainly hasn't left me with that warm, fuzzy feeling I've heard so much about. I know what Blackstone said about not worrying about the elevated metal numbers, but...I am.
I'm all to familiar with the issues surrounding Ecoboost engines and long oil changes, but this was only 4,500 miles! The OLM was still at 55% for pete's sake. Between the iron, viscosity, and fuel dilution numbers, I'm backing down to 4,000 miles on this current fill. I do plan to continue using QS Full Synthetic in order to eliminate variables.
Please, those that are more knowledgeable, give me your thoughts and suggestions.
