Comment — “Scaling back your miles this time has helped lead drop back to the normal range, but iron, though improved as well, was still reading about average. We’ll watch iron, and as long as it keeps decreasing we won’t worry too much about it. Potassium and sodium were noted again but are nothing new for this WVO runner. The viscosity read in the 15W/40 range and the oil showed no signs of fuel or water contamination. The TBN read strong at 7.3, indicating lots of active additive still remained. Still with 4,000 to 5,000 miles until iron gets back down to average.”
