6.4 how to get better mpg

I am looking to get a 6.4 in a f-250 or 350. I was wondering what people did to their truck to get better mpg. trying to not waste money on things that don't work. I was told that 6.4 only gets 16 mpg. is this true?

how much better do you want than 16? might be able to get 18-20 if you baby it but 16 is about what any diesel truck will get. you can delete your emissions equipment to gain possibly a few more

I got my 2008 6.4 used with 27,000 miles on it. With the 6-speed manual I was getting 16.7 mpg highway hand calculated... I experimented with speed a little bit. If I keep it under 60 with the 3.55 gears, I was getting around 17-18 calc, with the meter telling me around 20-22. If I hammer on it and go 70-75 I was getting closer to 15.

Overall on longer round trips I am still averaging about 16.7 by hand. Doesn't really seem to matter how delicate I am with the skinny pedal. My round trip has alot of elevation changes in western PA.

I need to do some experiementing with a Tonnue and a DPF/EGR delete and see if it shows any improvement. After that maybe we can see what a hotter tune might produce.

At present this thing is bone-stock other than the DPF back 4" stainless exhuast.

As far as mileage is concerned, I am impressed with the truck. Truck weighed out at 7800 lbs on the scales at work... And I used to drive a 3.0l V6 Ranger where I was getting about 21-22 MPG... Needless to say that isnt a bad drop in MPG for a significantly larger truck.

I had a ram 1500 with the 5.7 hemi and it would get 16 mpg hand calc'ed. My 6.4 with all emission control devices on it get 15 hand calc'ed. Not bad considering the weight and gears. I have 3.73's on the F 250 I had 3.55's on the ram
