This is my first UOA on my CDI. Have owned for ~70k miles, and always fed Mobil 1 TDT 5w40 CJ-4. Found a deal thanks to BITOG years ago. I had been following the maintenance minder on the car, which usually calls for a change at 13k. I changed this at 10k as I wondered how things were faring.
Mann or Mahle oil filter, can't remember.
Car is driven 70% highway, with mild traffic. Most other driving is secondary roads with very little stop and go. Looks safe to extend to 13k, right? Iron seemed a little high, but appears in line with this family of engines. Viscosity is up a bit too, but doesn't seem too far out of spec.
I can't find too many UOAs out there for this specific engine, but the 5 cylinder OM647 is in lots of Sprinters. Analysis for same engine at 6k miles:
