I did a little experiment the last few days since I was doing a lot of highway driving. Tried to keep the speed at 65 or below, and focussed on staying out of boost entirely and keeping the boost guage as far into the black as I could. Managed almost 31 mpg from my '87 740 Turbo, wow, I was amazed, the highest I'd *ever* gotten before was a hair under 27, with 25 being more typical highway mileage. It took some concentration but I didn't really have to go much slower overall than I normally drive.
