“Let's take a drive into the middle of nowhere with a packet of Marlboro lights and talk about our lives.” ― Joseph Heller, Catch-22

The best fuel mileage on an OM617 that I owned was 40MPG back in 1986.
The car was a 1976 300D & it had a very weak injection pump when I bought it and wouldn't go past 68MPH.

After having the pump rebuilt the car would go 82 MPH & get about 31MPG.

One time I brought a NEW 1985 300DT (3 miles on speedo) from the port in Jacksonville to Atlanta & it made 33MPG at 66MPH max speed.

My 1982 300CD only averaged 24MPG around town.

My NA Euro 5-speed '84 300TD has managed around 30 mpg-highway, and about 25 in town if I don't use the AC. That's about 1-2 mpg better than my '82 stick 240D, and about 5 mpg better than my '82 automatic 240D.

Happy Motoring, Mark

..I also have a 427 Cobra replica with an aluminum chassis.

When I got the car I got 32-35 MPG. Once, on a trip to Logan, UT, I got 37. Now I consistently get 23-25 Mpg. I did turn the ALDA screw tough, and I get noticeably more power from the get-go, but that came with a sacrifice in mileage per gallon.

My first trip in the Euro TD, I got about 30 mpg at 65 mph, with the AC going.
If we all limited our highway speed to 50, I'm sure 40 mpg wouldn't be too hard to reach.

Happy Motoring, Mark

Or at least a lock-up converter.

My 5-speed TD has the 3.46 rear.
With the 3.07 or 2.86 ratio the turbos use, that should provide some additional economy at highway speeds. But the automatics probably rob most of that.
Or there are alot of tired automatics out there.

Happy Motoring, Mark
