Cummins' Tips on Driving for Fuel Economy

[slowmover]

Glad you got those links up. Some of the other Cummins-specific information is, as you noted, for big truck operators. There is at least one Cummins calculator about truck spec, use, etc, that always recommends a higher rpm than pickups in general use will need, as with this post by Hohn, a Cummins Engineer.

Another post by that same gentleman goes into some more depth about proper rpm range for fuel economy.
