Comments — “Nothing unusual turned up in this report. Wear metals still look fine, and the extra lead is probably more a function of the type of operation you do with this engine rather than any sort of bearing problem since lead isn’t any higher than we’ve seen in the past. Iron is a bit higher than last time, though since iron tends to accumulate in the oil during a longer oil run, that likely is the explanation for that. A minor amount of fuel was detected in this sample, though 0.5% isn’t enough to solicit any concern. The TBN is still just fine at 7.1. Try for 8,000 miles on your next fill.”
