fj,
You can't use the raw data from the sample unless you extrapolate it. The full recommended oil change interval should be over 5000 miles. You tested at 2000 miles, and suppose you had checked it at 200 miles. What would those results have been? In my opinion oil should be sampled for trace elements after it has run its full course following mfg recommended intervals.
Boostnbenz,
Please explain boron and lots of life left in oil. Thanks.
Peter
