Nothing from Terry yet. He is probably away at this time.

5,000 miles on Red Line 5W-20 in Maybach 57, 6,700 total mile on the car

Gary's theory might be onto something. For 6,700 total miles on a 5.5L 550HP V12 that is driven briskly, occasionally, I think this is a pretty decent UOA. There's probably still at least a few parts getting to know each other in that engine, not to mention the Red Line chemistry trademark signature.

I would guess the numbers are due to the engine being new and Redline oils work.
I am still curious about the numbers. It is not due to the new engine, because even the virgin Redline numbers are high. Gary's 10x theory might be correct, but it is still strange.
Could the Red Line oil be cleaning the engine up a bit? A few more miles might help clear up the picture. Are the samples taken when the engine is really up to operating temperature? Would it be better to choose a lab that works only with high performance engines? I'm sure that Butler is ISO Certified, but maybe a lab with a focus on high performance or racing would be a better choice.
I also wonder if the high moly in Redline is also micro polishing a bit. I'd expect the larger particles to be more prevelant if this was were from the oil being too thin but I'm guessing.
The Dyson analysis was consistent with a lot of engine dirt and assembly debris being thrown around and cleaned up. He feels there was fuel dilution added to the oil that is not showing up. This is consistent with my around town driving.
The particle counts are additives in the Red Line and some are dirt in the oil. He advised the oil be changed, this was done at this time.
5,000 oil miles is enough time for an oil cleaning up the engine this much.
He did not think the oil was too thin or dangerous in some way but wanted me to keep a closer eye on the UAO after this change.
I think I will go maybe 250 miles and get a baseline UOA, then check again at 1,000 and 2,500, 5,000 if all looks better this time around.
