Not on a diesel. The amount of fuel used to travel is directly related to the power required to move the car at that speed, it has little to do with the rotational speed of the engine. When I had my '85 190D I spent a bunch of time comparing my commute mpg between 4th and 5th gear. I could never find an appreciable difference in mpg, I saw a much bigger variation when using snow tires...

Maybe at the cost of worse mileage overall if the turbo isn't spooled up enough at average travel speeds. Hmmmm. I will have to experiment. I see my rear control arm is getting rusted through on the bottom so I will be dropping the whole rear suspension assembly to replace that. Guess that would be a good time to swap over some parts from the wagons.
