A couple of comments that may be helpful...

First, your mileage should be roughly doubled to provide meaningful comparison with other MBs. Because your rear end ratio is so high your engine will turn over roughly twice as many times for each mile travelled. This would translate to halving the maintenance interval too - maybe to 1500mi vs 3000mi for a "normal" vehicle.

Second, the forces within the engine vary as the square of the velocity, specifically F=mv2 ("2" is squared not x2)...double the speed, 4x the force. At the same cruise speed, therefore, you have 4x the forces acting on the crankshaft, pistons, connecting rods, bearings, and so forth, which would presumably create larger than normal wear.

If it were me, I'd limit my speed to keep rpm at or below 3000...
