From Polaris Labs.
Truck Odometer: 223400 mi
Miles on oil: 12000
1 quart of makeup oil added since oil change.
Wear Metals:
Iron; 27 ppm
Chromium; 1
Al; 2
Cu; 1
Lead; 2
Contaminants:
Silicon; 5
Sodium; 8
Multi-source metals:
Moly; 70
Boron; 42
Additive metals:
Mag; 1239
Calcium; 900
Phos; 1122
Zinc; 1316
Fuel Dilution Soot Water
KV100 = 15.0 cSt
TBN = 7.3
Oxidation = 13
Nitration = 9
Another thoroughly boring oil analysis report on my Dodge. Compared to the last sample I took at 12k miles, Iron is down 35%, and the oil has 10% higher TBN. Everything else is about the same. At 223k miles, I think the engine is finally getting broken in. I'll do another sample in 12k miles, then decide whether or not to extend past that.
I do need to figure out how often to change the oil filter if I'm going to such long OCI's. I still have the PurOne from my 24k OCI from last year. I've been meaning to send it out for a professional analysis, and hopefully get a recommendation from the lab.
