Steady-state is lowest, all other conditions exert a penalty.

It’s the stop-n-go in town that separates men & boys. My pickup or with a 68,000-lb tractor trailer it’s about being smooth. Never stopping, only gliding.

I took the challenge about ten years ago from our world champion Cummins engineer Diesel Dave that only stop/go separates highway from city. MPG. Difference is too broad.

Agreed. So took my 18-mpg around town to 22. Every trip planned (after all combined); no left turns, etc. Plenty of discipline to pull it off.

In turn that made my combined average (all miles) 24-mpg (26 highway and 22 city).

Otherwise it’s 19. 21 if I work at it.

The savings with modern emissions diesels doesn’t start until nearly 200k miles. Not with family use. A gasser is easier to live with.

PLANNED USE is the FE key, then. (No one stop trips).
