What kind of highway mileage are you guys getting on your 6.7L's. I'm looking at 2500 4x4s and want to know what to expect. I will do very limited towing, mostly just drive it on the freeway.

 

when my truck was stock i was avg 18 highway and 16 in town with my mods now im getting around 21 on the high way and 17 in town hand calculated

 

Before my 22.5's all stock i was getting anywhere from 12-13 in town and 13-15 on road with cruise control on 60. Not worth a **** really. Now i get 10-12. 1 ton 4x4 6 speed manual. 3:55's i think?

 

I get about 16-17 usually on the hwy running 80-85 mph and don't really worry about it around town. I babied it up and down the road all last week running 65-72 mph and drove it like there was an egg shell between my foot and the pedal and got 21 mpg hand calculated. I was amazed to get over 700 miles outa the tank.

 

about 21 country driving. thanks to smarty

 

I am avg'n 18.5 per overhead computer on the highway.
14-15 in city driving. I have tons of start and stops in the Dallas area...

 

just hit 45k and the mpg are starting to slowly come up. for the first 30k i was getting 10-11 around town and 12-13 on the hwy. now i'm up to 13-13.5 around town and 14-15 on the hwy at 70-75. this is on my 07.5 with the 12'box/sail 4:10s the 6spd auto and a good load on it. i love this truck. its got to be the fasts bread truck around.

 

MPG has direct relation with how heavy the right foot is, and percent of city to freeway driving.
I got over 30K, have gotten ride of all the problems! and using Smarty at level 3.

I am getting average weekly driving of 17.2 MPG. I fill up every 525 to 550 miles and hand calculate my consumptions.

FYI, I got one of those heavy right foots!!
If I drive like my age, I get at least over 19MPG average.

 

Unfortunately, I am averaging 11-13 in town and 17-18 on the highway. less than 25K miles on my 6.7... I have heard you get a break around 50-60K. No mods - all stock
