Mobil delvac 15w40 CK4 since new.
15,625 miles on truck.
4,969 Miles on this sample. 3rd oil change.
No oil added.
Aluminum 7
Chromium 1
Iron 25
Copper 85
Lead 1
Tin 1
Molybedenum 23
NIckel 0
Manganese 1
Silver 0
Titanium 0
Potassium 21
Boron 39
Silicon 17
Sodium 4
Calcium 1350
Magnesium 562
Phosphorus 686
Zinc 787
Barium 0
SUS viscosity @210 f 65.2 (should be 68-82)
cat viscosity @ 100 c 11.67 (should be 12.4-16.3)
Flashpoint F 405 (>410)
Fuel % 0.5 ( Antifreeze % 0.0
Water % 0.0
Insolubules % 0.2 ( TBN not run for this batch.
TAN not tested
Blackstone noted the high copper, as was expected from these engines breaking in. However the low viscosity may be from the quick drive after startup without getting to full highway temps for awhile they seem to think?
Would like your opinions!
Thanks
