Just curious, at 10,000 mile OCI's what was the iOLM reading for oil life left. We have a 2017 Explorer with the 2.3 EcoBoost and when my wife was still working and commuting it was heading to 0% life at 10,000 miles all the time. Since it's an EcoBoost I usually changed it in the 6,500 to 8,000 mile range based on convenience. She retired the end of this past November and the iOLM is dropping faster with less miles driven. We use Mobil 1 5W-30, either the "vanilla flavor" or the EP, which ever I can get for less, both have performed well in the UOA's I've gotten and posted.
