The iron levels were 35 ppM last time with about 7K on the odo. The iron levels this time were 16 ppM. They figure it was due to longer than normal oil life and "driven hard" or "overheating condition." I've done no hard driving with it and I do not remember over heating it. Other than that, they can't explain why.What caused the elevated iron levels? What were they?
Standard Ford 820 Filter.Hmm interesting perhaps the filter was at capacity... which one do you use?
That worries me a bit because I am using 6-7k intervals on my 98 crown Vic... perhaps I should change the oil more frequently....
