This oil was in service from october 8, 2014 to april 1, 2015. I was very happy with this oil as the engine was still fairly quiet at 5k miles. Not like when the oil was fresh of course, but the quiet/smoothness lasted far longer than QSUD or Synpower. Considering the winter we had, I didn't expect the TBN to be so strong at drain time. The filter was a motorcraft FL500s and I used this same QS/MC oil and filter again and glad I did. This is a 3.5 NA V6 with 44,593 miles. No oil added and it stayed on the full mark throughout the oci.

Comments: dusty, wear metals look great once again. The viscosity is in the 5W20 range and theres no excess fuel or coolant contamination to worry about. The oil filter struggled to keep up last time, but no such issues here. Insolubles are a low 0.2%. The air filter kept silicon under control as well. The TBN is 3.3 showing active additive left and TAN is 4.9 having a bit more acidity than last time. A longer run should be no problem. If you're interested try 8,000 miles next time.
