FWIW the comments from my Blackstone report. 257k on the motor at the report.
No real surprises here, since this is the same oil that we tested back in June, just with a lot more
miles on it. Since iron was a little on the high side to start with, and it's the one metal that should track with
time on the oil, this level isn't so bad. In fact, if we take away the 15 ppm of iron that were present at 100
miles on the oil (probably residual from a previous fill), then just 31 ppm of iron have accumulated in the last
7,316 miles -- not too bad at all. The trace of fuel isn't an issue, and neither is the low viscosity. The TBN is
okay at 6.2. Try 9,000 miles next oil.
