Historically iron has crept up. On previous tests at
19,500 on oil FE was 36
6,000 FE was 15
10,767 FE was 34
4,365 FE was 11
11,600 FE was 27
As the mileage goes up so does the FE, I am running no mods, a Ford AIS severe duty air filter and doses of FP 60 and LC 20. The increase in iron really has me worried. The turbo housing and bolts are secure and no appreciable leaks, although the front seal appears to have a very slight leak, just dirty. The front seal was changed at 29,000 miles on the truck. Do not know if that could be an issue.
