Blackstone Oil Analysis after 5100km
During this first 5200km I added 1L of Mobil 5W40 Formula M. I changed the oil at 5100km and send a sample to Blackstone for analysis.
Here are the results.
Anyone else with an AMG 63 engine to compare with?
Comment: We're not sure how much is "too much" but you mightwant to keep an eye on your oil consumption as changes in how much oil you have to add can signalchanges in the engine's overall condition.
At this point, nothing unexpected turned up.
Metals and silicon arehigh, but that's common in brand new engines and you should see improvements with time.
Averages show expected metal readings following the break-in period after about 8,800 km on the oil.
The viscosity measured in the 10W/40 range. The TBN read 2.9.

You metals are high, but this is probably your first oil change and that is to be expected.
TBN is good. I think it starts off at 6 for M1
nickel was 5, which was a surprise. Turns out the tappets are 9310 steel with 3->3.5% nickel. You guys have a value of 1.
Now I started to worry about the lawsuit and abnormal wear, but they are also 93% iron. And I had no abnormal wear of iron. Anyone have any other idea where it might be coming from?
Everything else looked excellent.
I will try and post when I can find the pdf.

Oil analysis is a quick, nondestructive way to gauge the health of an engine by looking at what's in the oil.
What does a standard analysis include?
In our standard oil analysis, we perform four tests:
Spectral exam:
In the spectral exam, we take a portion of your oil sample and run it through a machine called a spectrometer. The spectrometer analyzes the oil and tells us the levels of the various metals and additives that are present in the oil. This gives us a gauge of how much your engine is wearing. To learn more about the elements we look at and where they come from in your oil, go to our Report Explanation page.
Insolubles test:
The insolubles test measures the amount of abrasive solids that are present in the oil. The solids are formed by oil oxidation (when the oil breaks down due to the presence of oxygen, accelerated by heat) and blow-by past the rings. This test tells you how good a job the oil filter is doing, and to what extent the oil has oxidized.
Viscosity test:
The viscosity measures the grade, or thickness, of the oil. Whether it's supposed to be a 5W/30, 15W/40, or some other grade, we will know (within a range) what the viscosity should be. If your viscosity falls outside that range, there's probably a reason: the oil could have been overheated or contaminated with fuel, moisture, or coolant.
Flash Point test:
The Flash Point test measures the temperature at which vapors from the oil ignite. For any specific grade of oil, we know what temperature the oil should flash at. If it flashes at or above that level, the oil is not contaminated. If the oil flashes off lower than it should, then it's probably been contaminated with something. Fuel is the most common contaminant in oil.
