Fuel mileage W900 Cummins X15

Id say 7 mpg if you keep your idle and speed in check. You can get 8+ with an aero truck with auto trans. Id say you'll get at least 6.5 regardless though.

 

Yes, thats what I run. T680's with endurant 12 speed autos. Fleet average is 7.5 but some drivers get up to 8.3 mpg. Thats governed at 70 mph. No doubt running 65 mph would increase mpg by a few tenths.

I only have 1 manual left but its a 680 with a 13 speed and its routinely around .5 mpg less then the autos.

 

Lmfao its a brick. You don't buy a brick for fuel economy.

 

Pete 389 with x15 performance 605hp 2050tq 18sp 3.55rears 11r24.5 tires. I average 6 mpg. You should be right around there. 5.5-6.5

 

With that specs you hauling definitely something very heavy.

 

A guy who runs Midwest-Northeast all the time with general dry van freight, told me he averages 5.5mpg in a 2020 one. He also said it's a complete lemon, $143k in warranty repairs already and he is getting a new truck in November.

 

Running flatbed. I'm at 80k all the time

 

I’ve got a 2018 international LT with an Cummins X15 efficiency series Eaton Fuller automatic and I get 7+ on paper. I pull Flatbed and most of the time I’m hauling 75+. May want to look at something that is Areo.
