Ecky, I am currently getting 40.25 MPG highway MPG over the last 6 months with the D15b7 motor coupled to the 4.025 Final Drive transmission for a freeway cruise speed of 3100RPM at 70mph.
I religiously separate my highway and city miles.
My "city" (rural sprawl area) MPG is much higher due to hypermileing by accelerating from a stoplight or up a hill, and then gliding down the other side with the engine off to the next stoplight. I live on top of a hill, so the first mile of my drive every day is done with the engine off until I get to the bottom.
Just filled up with gas again in prep for a drive on the highway tomorrow. was down to only 2/3 tank remaining.
Over the last two weeks of ONLY driving on the rural roads around here, i have traveled 220 miles on 4.475 gallons of gas for 49.27MPG.
I think it will do a lot better on the highway with a gearing swap.
