My local oil change/fix it man who changes my oil in my 2012 Nissan Pathfinder uses Cam2 Super Pro Max syn blend 5w30 motor oil and I usually change it out every 7,000 miles. The other day I was on PQIAMERICA.com and I was reading a test report of this oil and it looked ok other then the fact that the TBN looked to me to be on the low side 6.53 is this something to be concerned with? Would it be best to run this oil for 7,000 miles and do a UOA with TBN report to see just how low it is at that millage?
