My '87 190D turbo automatic got around 36mpg every day on the freeway with the cruise set at 74mph. On a regular commute on 55mph 2-lane when I was good to the loud-pedal I would get 40.5mpg. The turbo car is a fuel-mileage king for a mid-'80s 3300lb car.

Turbos do increse the efficiency on a diesel.
