You have inspired me to check the mileage in my grey car.
I should get it running again first... funny how one simple fix disables my stuff for months.

Its a 82 300D, kkk swapped, 4 speed swapped, and 2.87 rear end ratio.

My 80 SD usually averaged around 25 with no highway, mostly all 55mph roads in NY.

Now that I'm in TN I've noticed mpg numbers fall off the edge of the planet in everything I own thanks to hills in every direction and 35ish mph speed limits on most roads I drive.

Don't ask about any of my trucks mpg...
