Well, just got the results back from my first oil analysis at AV-Lube. Changed Oil/Filter at 1K to Rotella-T, again oil/filter at about 5K with Rotella-T. Justed switched over to Rotella Syn, and this sample came at that oil change with about 5K on the oil.
Here are the results:
Wear Metals
Iron: 15
Chromium: 1
Lead: 8
Copper: 22
Tin: 8
Aluminum: 4
Nickel: 1
Silver: 0
Contaminants
Silicon: 26
Boron: 1
Sodium: 8
Potassium: 5
Additives
Magnesium: 28
Calcium: 2882
Phosphorus: 1562
Zinc: 1600
Molybdenum: 4
Physical Analysis
Fuel: A
Water %Vol: <0.1
Glycol: N
Visc 100c cST: 15.1
TBN: 10.2
Soot: <0.1
Oxidation: 14.00
Nitration: 6.00
_____________________________
Copper and Silicon were flagged as slightly above normal. In the comments section it read:
Dirt level slightly above normal. Copper level slightly above normal. Possibly from bearing overlay, thrusts, bushings or cooler. No corrective action at the time. Continue Normal PM. Resample at normal interval.
OK, now for my questions:
1. I seem to remember somewhere that an elevated copper and silicon level is fairly common no the Dmax. Is this true, and are these numbers in line with what others have seen?
2. I assume that the fuel rating of "A" means absent or something...ie, no fuel in the oil.
3. To those with a lot more experience with this, do any other values seem out of whack?
Thanks,
John
