It takes a lot to fully kill one but consistently over revving the engine kills them sure as the sun also rises .
Over 55 MPH and the W123 chassis begins to suffer low fuel economy so no , driving a 300D @ 70 isn't where it wants to be , nevertheless I drive my Coupe that speed and faster whenever I want , the crappy fuel economy is offset my ht joy of driving it fast .

When I had a 240 I took it to LA a few times and beat it to death...didn't die. I suspect it was the Italian tune up scenario. I have noticed a great variance in speed when going into a head wind. You don't notice the wind until you stop. So I can tell you it matters greatly. Lawrence Rhodes...300's do better over 70mph.

The hill power seems to vary ;
Sometimes it breezes up hills @ 60 ~ 65 MPH , others it lags and slows down to 50 MPH or so .
I'm at a loss to say what the deal is .
This is almost always with just me and a bunch of crap (100 # or so) in the trunk .
Being a slushbox , having even one passenger slows things up quite a bit .
Nevertheless , I've driven it many times to Los Vegas fully loaded up with five adults and the trunk full of luggage , over the hills and it goes right along for the most part . I drive it 60 most of the time to get top fuel economy .
Driving a slushbox equipped 240D over 65 ~ 70 MPH is beating the crap out of it , don't complain when/if it screws up after much of that .
I also try to keep a sharp eye on the valve adjustments and filters etc.
This time the fuel in the clear plastic intake screen was tea colored , I tapped it a bunch with a screw driver handle before slacking the clamps and didn't see the usual chunks of dead fungus ~ a few tiny black things that blew right out leaving me with a clean filter screen so I reinstalled it filled up and went on my way .

I'm curious as to what route you took, the speed you drove and any modifications to the gear ratio. Also what kind of power does your 240 exhibit over hills. I've seen 240's tackle the Altamont pass on the 580 freeway at 65mph while mine barely did 50mph(300TD).of course I'm running veg oil. But not all cars are equal. I've had a number of diesels. The best was an 83 240 which nothing seemed to faze it. It would do 60 over the pass on Veg oil. Slightly better on diesel. Lawrence Rhodes
