I took a sample to follow up on the previous analysis that was showing a spike in Lead.
Yes, I put 16k miles on the truck in about 6 weeks.
This oil fill is all new-bottle RT6 CK-4.
From Polaris:
Truck Odometer: 338500 mi
Miles on oil: 16000
4 quarts of makeup oil added.
Fleetguart Stratapore filter.
Wear Metals:
(Element (ppm); 235k, 322k, 338k)
Iron; 42, 52, 30
Chromium; 3, 3, 1
Al; 4, 5, 3
Cu; 3, 4, 1
Lead; 9, 31, 4
Contaminants:
Silicon; 6, 13, 7
Sodium; 8, 6, 5
Potassium; 62, 0, 1
Multi-source metals:
Moly; 75, 76, 5*
Boron; 83, 38, 112*
Additive metals:
Mag; 1333, 1198, 179*
Calcium; 960, 1111, 2174
Phos; 1138, 1104, 1012
Zinc; 1439, 1471, 1277
Fuel Dilution; Soot; Water;
KV100 (cSt); 15.1, 15.1, 15.3
TBN; 6.54, 6.99, 5.69
Oxidation; 15, 16, 14
Nitration; 10, 10, 9
Polaris Comments:
Flagged data does not indicate an immediate need for maintenance action. Continue to observe the trend and monitor equipment and fluid conditions. Flagged additive levels are different than what should be present for the lubricant identified for this component. This does not imply that the lubricant does not meet proper API, SAE, or ISO classifications.
*Polaris flagged the Moly, Boron, and Magnesium, contents because they didn't agree with the RT6 values in Polaris' database.
But the good news is the Lead spike seen in the previous analysis is gone, and the wear metals are all low.
ZDDP content is down about 10%.
Moly is essentially gone.
Boron is up, as a replacement for the Moly, perhaps?
Magnesium is down about 85%.
Calcium is almost double.
TBN is already lower at 16k miles than the previous sample was at 37k miles. But that being said, the new sample still has a lot of life left in it.
