BUT< his truck sure is nice inside and out and if I didn't have a 70 mile a day commute I'd probably get one and forget the milage. I guess it's just another of the tradeoffs. We all have to decide what's important to us.

I am averaging about 16mpg, but my truck only has a few thousand miles on it. Once I get some miles on the motor, and switch to 4.10's, I am sure it will get much better. You have just broken in your motor already. That is the trade off with having a brand new truck. My 03 had 160,000 miles on it, and it got 20+mpg. I also have a heavy foot, so that doesnt help.

"Hey Smitty,
Do you have a 5.9 or a 6.7? 17 on the highway, is that at 70-75 mph? if so I can handle that. Not looking for grocery getter type mileage just do not want to be looking at 15 on the highway. Will be going to larger tires just nothing to extreme. Thanks everyone for the replies. Also ordered the 4.10 just cuz I am drag racer at heart, could not help myself, ya know what I mean?"

It's a 6.7 17" tires about 70 MPH.

Well i also have 3.73's which worked well until I put bigger tires on, now I wish I'd ordered the 4.10's. If you plan or installing a suspension system that includes good wheels..You have to pay little more..

i think some people just kike to say 4.10. comparing a 5.9 4 speed auto to something with a six speed is kind of off topic here though.

I am just simply trying to help out. I found this topic on the home page, and figured I would chime in about what I was going to do. Also, fill out your signature, so others can see what you have. Just my .02cents

if you don't own a 6,7 with a 6 speed tranny (auto), your answers mean nothing, post on the 5.9 forum, older 5.9's get better mileage (less hp, lower gears if really old), all the 6.7 forums have the same problems, people posting numbers on 5.9's with 4 speeds, pain in the rear

11450 miles on mine and I am averaging 13mpg mixed conditions and includes pulling 20 000lbs for round 25 miles on my last tank. I should also mention that also includes drifting to 85mph due to how sweet she rides....
Cheers Derek

I have been getting a solid 21mpg hand calculated over all. that includes stop and go traffic on the interstate that i deal with daily, regular "going to the store" driving and highway.

SO my average is 21.

You will see more mpg after you have 50 turns on your motors. They are not broken in yet. My mileage went up after that. I see 20 hiway empty and 14 hiway towing 8,000lbs criusing at 70 mph.

Sorry to hi-jack but I was thinking of putting 35's on my '06. I get around 17.5 mpg combined with 3:73's. Should I expect much of a drop if I do put the taller tires on?
