All OA results are in the attached OA on page 1.Thread now painfully long to read through.
High Silica in UOA.
Out of curiosity, do you run Blackstone tests at 10,000 miles?
What are the silica levels?
I don’t know what the silica should be at 25K miles because very few people run 25K mile OCI.
Many people run 10K mile OCI and so there is a good baseline average established.
My own opinion is you need a dual filter bypass filter like I said in my first post.
It is very impressive that you have worked that engine so hard and it does not burn a quart of oil in 25K miles.
It doesn't burn a drop, Im very impressed and to say Ford did a great job is a understatement. I do some hauling but Im guessing that only around 20% has anything more than a 1000# Jetski and trailer behind it.
I make a 500 mile round trip at least once a week, daily commute is at least 150 miles and on weekend the truck has more room for wife a kids. This truck doesn't get any rest, very impressed with everything about it.
