Here is the latest UOA for my wife's 2010 Ford Escape with 2.5L I-4.
The oil was Pennzoil Platinum High Mileage 5w-20. It required no top-up oil this run.
For the last two oil changes, the OLM has been extremely conservative, asking for new oil at about
2000 miles. In the past, it would not request new oil until about 7,000 miles.
The Escape has been running normally, no overheating or anything like that. But it has been
short-tripped extensively in hot weather over the summer, and now Blackstone has flagged
an increase in iron.
A) should I worry about this?
B) why is my OLM suddenly so conservative?
C) are the iron issue and the change in OLM behavior related?
Thoughts?
