Wow, that is very cool! 27.9 MPG in a full-size pickup. The 700.1 miles/tank is truly astounding; that's big rig/dual-tank type stuff!

I thought you guys were out of DEF fluid? Why still no mention of it. It really needs to be included in all MPG calculations.

DEF is not fuel, and the DEF refills are infrequent, so I would leave it out of MPG calculations. I would treat it no differently from oil -- i.e., it is an occasional expense that should be factored into the overall cost of ownership. Just think of all the BMW posts where Edmunds said, "The oil indicator was low, so we added a quart this week."

DEF is not fuel, but it's use is tied to the combustion of fuel, while oil is not. I think the cost of DEF should be accounted with fuel, while oil is a maintenance expense.

DEF is not tied to the combustion of fuel...it is Diesel EXHAUST Fluid...it helps burn off exhaust so the emissions coming out of the exhaust are cleaner. It does not mix with the diesel fuel at all. Please people do some research before commenting.
