I think you mis-understand me..
I'm NOT saying drive like a "grandpa" all the time..
But, driving in 85 on a highway, even in fourth gear will give a rather high rpm.. Wich is something you usually won't get in a newer Benz..
Also, depening on where you are in the states, the temperature, tyre-pressure, etc etc.. All are points that can prolong OR shorten your trip..
If driving in 85 in Nevada keeps the engine cooler, then it might be better to do so there.
Driving in the moutains, with some long up and downhill driving, a slower speed will likely keep both the engine, the brakes and the drivetrain in a better condition..
Also, the engine temperature don't need to match the temp of the gearbox, the final drive or the temperature of the grease in the wheelbearings..
