I don’t think we are in any degree of disagreement. We do a lot of the same things.

My MPG, like DD is my daily commute. Like DD, the road is familiar and my results are very consistent. I don’t think our driving styles are much different. I make use of the F350s weight and people call me Sir Coastalot although I don’t do any engine-off coasting. Just knock it out of gear and coast with the engine idling. I can time the lights pretty well, although this isn't easy in Indiana as they have no standards of light timing.

I use the A/C as needed.

I count my errands in with commuting and treat long trips as a separate set of data.

I have alternate routes that are slower and involve less stop-and-go but I don’t use them unless I have to (Indiana has two seasons – basketball season and road construction season) because they are 10-14 miles longer and the whole point is minimum fuel burn.

I’m sure that if someone comes along with a commute routine that is even slower (on average)but has less stop-and-go, he beat both of us. The road load equation will not be denied.

Most Ford guys view me as an oddball. I suspect the majority of the Dodge Cummins community see DD the same. They like to drive like Tony Stewart, then belly ache when they can’t get over 15 MPG.

All the same a road trip might be interesting. Maybe we could go visit Phil Knox. A bit under a thousand miles one-way.
