I've searched and searched the FTE forums, but am unable to locate an answer to why my truck's message center doesn't indicate oil life remaining when performing the system check function. My 2003 Mountaineer works properly.
I have the owners manual and repair guide, but no luck so far.

 

I have 05 Nav and it doesn't have any oil life indicators or reminders. Nothing that you can track besides milage and time. It just displays whatever it measures as ok or not, meaning fluids, battery, tire pressure levels, etc.
