Diesel vs gas......................

I've owned both the Powerstroke and the Cummins. Those of you used to the I6 diesel definitely run at lower RPM's (I'm still getting used to mine). Now, I am running 1500-2000 RPM while cruising and 2250-2750 RPM when passing on a grade. When I had a V8, the diesel was making peak torque at 2000 RPM and peak horsepower at 3300 RPM. I used to run 1750-2250 RPM while cruising and 2750-3250 RPM when passing on a grade.
I would guess that there is half the friction surface in a diesel than gasoline engine due to the lower revolutions, but you are operating at twice the pressures which causes wear elsewhere.
