Seeking expert help

[VladtheGlad]

From past posts, I have seen some of you are experts in reading oil analysis results. I am not! Could you folks, in the know, help me understand what these results mean> Thanks fellow Gladiators.

Wear Metals (ppm)

Metal	14-Jun-25	18-Aug-24	Comment
Iron (Fe)	38	46	Normal for this engine; dropped slightly.
Copper (Cu)	1	7	Minor increase; possibly from oil cooler or bushings.
Lead (Pb)	<1	3	Stayed low—good. Bearing wear not evident.
Aluminum (Al)	10	<11	Stable; from pistons or bearings.
Chromium (Cr)	<1	2	Minimal; low ring wear.
Other Metals	All <1	All <1	No issues observed.

Contaminants (ppm)

Contaminant	14-Jun-25	18-Aug-24	Comment
Silicon (Si)	23	42	Dropped — possibly residual from sealant or dirt ingestion.
Sodium (Na)	3	3	Stable — no coolant intrusion indicated.
Potassium (K)	13	10	Normal range.

Magnesium: 577 → 113
Calcium: 2059 → 2883
Phosphorus/Zinc: 914/1055 → 1067/1166

Verdict: Additive package is in good shape; oil is still performing well.


Viscosity @100°C (cSt): 13.1 → 13.6
Soot/Fuel Dilution: <0.1% (both samples)
Water: <0.05% (both samples)
Base Number: 6.7 → 7.5

Verdict: No dilution, water, or soot — combustion and oil quality are excellent.


All trend lines (iron, copper, silicon, base number, etc.) show either a stable or improving trend. No critical spikes. Base number decline is consistent with oil aging.


• No critical metal wear
• No coolant intrusion
• No fuel dilution or soot
• Additives intact
• Oil still viable





WARNING!!! I am not an expert by any means. ask @ShadowsPapa
