I'm getting abour 17 MPG for the average on my truck... Check the sig. Usually doing speed limits (55 & 65 MPH)

 

a dually will get 15 at that speed

 

yeah i`ll bet you do

 

I do and that is hand computed cause I dont have the overhead . So if you dont know my truck then dont say anything. Just cause you dont doesnt mean somebody cant.

if you see my sig i have the same truck and you are a liar or you are not driving over 45.either way you are wrong...we don`t need people to try feed all kinds of bs to us .... i have been around for a long time so i know!!!!!]

 

I get 20 to 21 with my dually on the highway all the time. If you go over 65 expect less. I don't go over 65. I got 19 for 500 miles with 3000 pounds in the bed last summer.
I also have 4.10 gears
It all in how you drive. If you race ricers you get 15 or less. If you do burnouts you get less besides wear out the tars.
Oh ya Mine is manual calculated. I don't even use a calculator.

 

My 2002 4X4 3/4 ton auto 3.55's gets 18-21 at 75 mph, depending on wind and all that good stuff. With a slide in camper, and my trucks weighs in at 10,007 pounds, i see about 14 at 70 mph.

Dont you call me a liar. My truck does get 24-26 mpg running at 70. if I go over 70 like 71 then the milage goes way down. I generally run with cruise set at 69 so that I do not go over 70. when I hit 75 milage comes back up some. This truck has done this since I got it. You do not know me and have no reason to call me a liar.

I guess you know this though as you have been around for a while.

 

you are the only one with a dually with that kind of mileage...i think your trying to blow smoke

 

I have a 2001 with 3.55 and 6-spd 4x4 and with a built in mileage computer so i have checked mileage a bunch of times at fixed speed over (almost) level ground at a constant speed


at 50 mph i get about 25-26 mpg

55-60 mph about 20-22

at 75 ( measured it last summer in North Dakota on interstate) about 17 mph


this is either running almost empty or with a small cap on the back-constant speed with cruise control

i am about to put in a slide in camper in back and hope it doesnt hurt mpg too bad

 

wind resistance with a cab over camper will kill your mileage

 

Shouldn't hurt ya too much......i have a cab over in the back of mine for the summer and i am getting any where from 12-14. I know mine is a 3/4 ton, but i have the auto, and my mileages are similar too yours!

 

Nope sorry the only smoke i blow is when i shift.

Like I stated earlier it does do a few weird things.

Upto 69mph or as long as it does not go over 2k rpm it gets 24-26mpg. the variance depends on temps.

between 70-74 mph i get maybe 15 mpg

between 75 and 84 it goes back up to almost 20 mpg

then I tried setting cruise at 85 before and I need a tanker truck followiing me to really go anywhere.

 

Just because an individual is new to a forum, doesnt mean that a new member doesnt know much. Someone can have extensive knowledge about these trucks, have owned more than a few, but not be a member here, then sign on. Just because they are new to the forum, that doesnt make them uneducated. On the flip side, I've seen long term forum members on other sites give out incorrect information to other members, so someones tenure at any given forum doesnt neccessarily mean your going to get correct information from that person.

 

Training wheels? What the? That's a good one.

For what it is worth, I can get 20mpg with my "training wheels" but only at 60-65 mph. But I have a 6-speed, not an auto.
