UOA results @ 363k

Comments — “Iron and lead are a little on the high side in this sample. Iron though isn’t too much higher on a ppm/mile basis. Last time you got 179.6 miles per ppm of iron and here you got 198.8 miles per ppm, which is actually a little better. Lead is higher than past samples though, showing some extra bearing wear. Potassium and sodium is probably just from the WVO, but these contaminants tend to attack bearings first, so that’s something to watch. The TBN was strong at 5.4. Try just 7,000 miles on the next oil and check back to monitor lead.”
