Original Post:
2007 Maybach 57s AMG delivered 6/2007 with 125 miles on the odometer. I took a sample after driving 15 miles home from work with 2,000 miles on the clock. The car comes with a twin turbo 6.0 liter V12 (my old “regular” Maybach 57 had a 5.5 liter V12). It has 612 BHP and 738 ft lbs torque. Driving: spirited around town, some highway driving, maybe 10 percent.
This sample has the viscosity of a low 40, almost a 30 grade oil. This makes me feel comfortable using a 20 grade oil.
The regular Maybach 57 did spec. several 30 but mostly 40 grade oils. This engine only specs. all 40 grade oils. Note that the smaller engine was rev limited to 150 MPH whereas the AMG engine allows for 175 MPH. This is a big difference in oil heating in my book. Since I will have no oppurtunity to go over 100 MPH there are no reasons to go with the 40 grade oil.
Aug/2008 Update:
‘Dyson analysis of this Red Line 5W-20 with 5,000 miles on the oil and now 7,000 miles on the car. I put in RLI oil now, running the 0W-20 grade. I will get another Dyson analysis after having 5,000 miles on this RLI oil and a total of 12,000 miles on the car.
I used up the tires (with proper rotation) at 6,000 miles. I like to light them up when I can:
June/2009 Update:
I just put on another set of tires, I only get 6,000 miles on them the way I drive. I did two UOA, the one on the most right from Dyson Analysis. Both samples were drawn into one container originally so there would be no chance of them being any different.
Also I put 2 other samples into bottles to be sent out several months apart. The experiment is to see how the results change if the sealed sample bottle is left to sit around for several months. Results to follow in the months to come.

6-17-09 Comments from Terry Dyson of Dyson Analysis:
The engine is still breaking in and nicely, rings are sealing better, no wear on turbos. The fuel was handled well by the oil, not thinning it at all. The 1 % fuel dilution value is correct as opposed to the 8 % value. The flash point is still nice and high.
This 20 grade oil is working well with this engine despite me lighting up the tires on a regular basis.
