M-1 0-40 - 13k mi. 2001 M-Benz E430

Got this from the Mercedes Forum and thought I'd post it here for some comments....


'01 E430 Oil Analysis Result - FSS & Mobil 1 @ 13K Miles

'01E430: I promised I'd post results of my oil analysis and I have it. The analysis was performed by Oil Analysis lab, Inc., Spokane, WA. My driving style involves daily short trips of less than 10 miles to & back from work, weekend highway trips, usually over 100 miles and usually at an average speed of 75MPH. Maximum sustained speed is 95MPH for several miles. Max speed attained is 120MPH, several brief moments since purchased. The FSS called for first 'A' service at just over 13,100 miles. At 13,066 miles I took it in. The oil is Mobil 1 0W40. The analysis is grouped in four categories - Physical Data, Metal Concentrations, Additive Package and Maintenance Recommendations (for those interested, the actual test data is given at the end of this post). In all but Metal Concentration, everything is normal. Infact, at 13K miles, I think that the oil did pretty well. In Metal Moncentration, Silicon is slightly less than moderate and its contamination is causing abbrasive wear (silicon is from airborne dirt). Aluminum and copper are moderate and should be monitored. Maintenance Recommendation calls for oil & filter to be changed if not done yet and that the metal concentrations are most likely from engine break-in.

Here's the result data:

A) Physical Data
Viscosity: 11.7 cST @ 100C
Fuel Dilution: 0%
Soot: 0
Oxidation: 0
Nitration: 0
Water: 0%
Anti-freeze: 0%
B) Metal Concentration (parts per million by weight)
Silicon: 78 - requires monitoring
Iron: 50
Chromium: 2
Aluminum: 28 - requires monitoring
Copper: 29 - requires monitoring
Lead: 19
Tin: 0
Nickel: 1
Silver: 0
C) Additive Package (parts per million by weight)
Molybdenum: 1
Magnesium: 709
Sodium: 21
Titanium: 0
Boron: 3
Potassium: 8
Calcium: 1457
Zinc: 1116
Barium: 4
Phosphorus: 1206


I'm somewhat concerned about the Silicon but don't know what to do about it. I'll resample at next oil change.

This is a total BS. This analysis looks like a bad-made fake.

According to VOA of Mobil 1 0W-40, posted in VOA section:
Mobil 0w-40 does not contain any magnesium (only 13 ppm if be exact), which listed here at 700. Mobil 1 0W-40 has molybdenum at 72, in this analysis we see no trace of it at all (only 1, which is nothing). Mobil 1 has a boron of 186 here we see only 3. Calcium for Mobil 1 is over 3200, here only less than half of that. Phosphorus and zinc amounts are also wrong, and etc.

This UOA is a total made-up fake, unless this is something different from Mobil 1 0W-40.

Original post was 1.5 years ago. Formulation for M1 has probably been changed a few times. Thought I doubt it would change so differently, but it is possible. Besides... don't confuse everyone by posting same results twice, especially if they are completely outdated (if they were not fake in the first place).

This is Mobil 1 Tri-Synthetic, the current Mobil 1 SuperSyn formulation is significantly different and much improved.
