to that... And yes, it does sound like a lot of oil and would most certainly bother me if it were my car.
As a side bar, I've only driven on the Autobahn twice in my life, and both times were with rental cars (obviously) so I couldn't care less about oil consumption. But it's amazing the amount of work an engine must be doing for hours on end with the loud pedal literally planted to the floor, and all without any drama or immediate issue! I guess that is why the German manufacturers are especially careful with their design and selection of service components to ensure proper operation in this type of duty cycle.
Hence why the typical Mercedes holds 8-9+ quarts of oil, and has large radiators for just about every fluid. Plus big cooling fans, under body air control to cool the rear end and brakes etc. Than you get into internal engine stuff like oil cooled pistons, 4 bolt mains, double row timing chains, etc.
They are designed to run at WOT until the tank runs dry.
The OP runs them fast but 120-130 is a very comfortable easy cruising speed in an S class.
Why else buy a Mercedes or an exotic.
