Received First Oil Analysis Today

[Luis]

2001 GMC Sierra 106,583 miles when tested. 17,082 on oil w/three filters when collected and tested. I’ve used AMSOIL ever since I purchased the truck with 4400 miles. Here are the results: NORMAL (as reported)
IRON 8
CHROMIUM 0
LEAD 17
COPPER 131 :confused:
TIN 0
ALUMINUM 3
NICKLE 0
SILVER 1
SILICON 12
BORON 1
SODIUM 0
MAGNESIUM 16
CALCIUM 3917
BARIUM 0
PHOSPHORUS 1135
ZINK 1426
MOLYBENUM 0
TITANIUM 0
VANDIUM 0
POTASSIUM 0
FUEL (%vol) <1
VIS @40c cSt N/A
VIS @100c cSt 13.24
WATER (%vol) 0
SOOT/SOLIDS (%wt) 0.1
COOLANT: NO
TBN 7.01
OXID 2.0
NITR 4.0
F-SOOT 0.05
The test indicated the copper was high and possibly from lube oil cooler.
How does this look to the experts out there?

Thanks MorePower...I read the other thread and it's my understanding that this high copper content is most likley oil cooler related. Is my (131) high reading any indication of potential failure? :confused:

Luis,

Your other wear metals seem normal and within the range of other Duramax UOA’s posted over at BobIsTheOilGuy.com (http://theoildrop.server101.com/forums/postlist.php?Cat=0&Board=UBB26&page=0). The higher numbers may be just due to the 17kmi extended drain interval … the longer you run the oil the higher the concentration ... You might try pulling a sample at 7.5k to see how it compares .. For reference here’s a recent UOA report from my 03 ..

Oil was topped off with 16oz of Power Service Diesel Lube Oil Extender near the end of the OCI

This is my first OCI with DELO 400 since the truck was new and it’s the best UOA to date … (click on UOA History in my signature) The truck now has old stock M1 T&SUV (5w40) for the winter .. If I didn’t live in the cold northeast I would run the DELO 400 all year round..

:)

JB...thanks for the reply...I will pull the sample after 7.5k and get a comparison. Thanks everyone:)
