Whatzup with this Staveley report?
I recently changed my oil (again). I always sample and send to Staveley's. Some of you may remember my endeavors with Blackstone, attempting to establish a consistent baseline on virgin samples....it didn't happen,...so,...off to Staveley's (since).
I can't seem to find my first virgin analysis of 20W50 Brad Penn,..but DO have my 2nd pass results of the SAME virgin sampled bottle,...as follows: Iron 2 Chromium 0 Lead 0 Copper 0 Tin 0 Aluminum 1 Nickel 0 Silver 0 Silicon 7 Boron 4 Sodium 593 Magnesium 650 Calcium 2090 Barium 0 Phosphorus 954 Zinc 1131 Molydenum 8 Titanium 0 Vanadium 0 Potassium 0 ViS @ 40 cSt 151.3 ViS @ 100 C cSt 18.98 Water 0 Soot solids & coolants N/A TBN 8.8 Recent sample during oil change with about 2800 miles on the oil. Do understand that I had been running RP MC 20W50 when I did the BP changeover (my previous oil change)...NOW, it's change #2 with the BP (again). Also,..I forgot that I had run a bottle of Techron through on a FULL tank,...early on, shortly after my previous change.....ANYWAZE,..here's the Staveley report on my LAST (BP #2) oil changeout: Iron 12 Chromium 0 Lead 5 Copper 6 Tin 0 Aluminum 4 Nickel 0 Silver 0 Silicon 7 Boron 5 Sodium 393 (NOTED AS HIGH, BY STAVELEY"S) Magnesium 390 Calcium 1969 Barium 0 Phosphorus 1837 Zinc 1203 Molydenum 101 Titanium 0 Vanadium 0 Potassium 0 ViS @ 40 cSt N/A (WHY IS THIS?) ViS @ 100 C cSt 16.45 Water 0 Soot/solids N/A Coolants YES, (WTF IS THIS?) TAN 1.4 (TES, THAT"S RIGHT FOLKS,..."TAN" (not TBN) NO IDEA WHAT THIS IS??>>> Charles N? Where are you? Lotsa question here,..where was the MOLY created? Whatzup with Staveley's flag of Sodium level? ("Appears to be high", as their report noted...rec: "checking for source of contamination/monitor") Time to call Staveley about their reports's listing of a "TAN"...Charles? Is this a separate measurement? Never heard of a TAN.. A typo? If so,..no way the TBN would drop that much, right? ...Just wanted to drill down on this,..see if anyone else out there had experienced the same thing... Comments most welcomed. Best,
