06 Duramax with 72,000mi. 10,000 mi on Amsoil Ame 15w-40 & EAO Filter Oil was changed at time of sample. Compared to a sample done @ 32,000mi this one is ca-ca
Iron 26
Chro 0
Nic 0
Alu 8 (flagged as abnormal)
Cu 5
Lead 0
Tin 1
Cadium 0
Silver 0
Vandium 0
Silicon 10
Sodium 3
Potasium 6
Titanium 0
Moly 5
Antinomy 0

Lithium 0
Boron 6
Magnesium 119
Calcium 3890
Barium 0
Phosphrous 1286
Zinc 1443

I'm glad I didn't run this oil and filter the full 25,000mi as Amsoil suggests. The Iron and Alunimum concern me. Maybe it's time to go back to Rotella and 5,O00mi change intervels.
