I hope you have a manual transmission. I had a diesel with the 5 speed auto, and even with the extra efficiency of the diesel, 30mpg at 60mph was the best I ever got.

There is a lot you can to to improve the aerodynamics. Remove the roof rack, install smaller or remove the huge ears (mirrors), grille block, air dam, belly pans, lower the ride height. If I recall, a fellow on was getting mid 30s from his CRD with some of those mods. He also installed a bunch of air tabs, but I doubt those helped.
I'm not coasting, I'm shifting slowly.
