I volunteered to post this gentleman's oil analysis results here. He was concerned about the oil emulsion under the oil fill cap and had the oil tested at work(I don`t know where he works). I have the same motor and emulsion with no issues. His following results are suspect and I recommended Dyson Analysis(he hasn`t committed to it). We would also like to hear any opinions on his results. Thanks in advance.
Oil - Redline 5w30
Miles on truck - 6348
Miles on oil - 3348
Miscellaneous
A/F - N
Fuel - N
H2O - Y*
Viscosity - 56
Infrared Analysis
Soot - 27
Oxidation - 79
Nitration - 126*
Sulfur - 0
Wear Metals(PPM)
Copper - 6
Iron - 46
Chrome - 3
Aluminum - 16*
Silicon - 12
Lead - 0
Sodium - 47*
Tin - 0
Nickel - 2
Barium - 1
Silver - 1
Zinc - 1296
Boron - 0
Calcium - 2551
Phosphor - 1201
Magnesium- 35
Potasium - 5
Molybend - 532
Titanium - 0
Vanadium - 0
* These items were what the lab marked as being concerned about.
Here are some comments the lab made on the sample report.
- Need to establish wear trend for compartment
- Positive water contamination
- Sodium commonly used as corrosion inhibitor in coolant
- Sodium may be from over the road salt(how did that get in there?)
- Nitration level is unacceptable
- Aluminum is reportable
- Water may be from condensation
- Resample to monitor
I figured I'd give this oil until 7000 truck miles and resample/change it.
