I've found one thing for certain.

Going over 2,900-3k RPM sucks the diesel. A lot.

I went down to Seattle this weekend and did 130km/hr most of the way at 3,100/3,200 RPM and I got about 650 km / 80L of diesel when I filled back up.

If I keep it at 100km/hr @ 2,700 ish, then I'm around 750/80L give or take.

... good.. bad.. I'm the guy with the gun.
