Another mileage post
Bear with me on this one.
First of all I have an '06 F-350 CC SRW 4 x 4 with factory 20" rims. The truck has 42K on it.
I'm in construction and and always hauling something or someone in it. My average has been 13.8 MPG for the last 20K miles with mostly short distqance driving.
I read about some of you getting REDICILOUS mileage and decided on my next long trip I would get serious and see what kind of Highway mileage I could get.
Well I just came back from a trip to the Outer Banks of NC which is a little over 900 miles RT. My average with mostly highway miles came out to be 19.45 MPG. Un freggin believable !!!
The lie - o - meter in the truck was as high as 21.8 at one point.. Not bad for a truck that weighs 6000 #'s.

Thats awesome. I have a ton of in town driving I do, short trips...etc so I only average 12.2 mpgh. But with my boat behind me on the highway I get 18.4 mpg. It takes alot of fuel to get that truck from a dead stop up to speed, but once its up to speed they don't do bad.

DC-
My average speed on the highway was probably 65 MPH. I used the CC as much as traffic would allow.
It is also interesting that my trip "down" to the beach involved a drop in elevation of about 1000 feet and I averaged 19.6 going down but comming back where I climbed that 1000 feet I averaged 19.3.
06-
I towed my race car to Savanah, GA back in Feb (24' enclosed trailer ~ 8000#'s and winter blend) and I was traveling with some other guys and we were running about 75 to 80 MPH and I got about 11 MPG so I think speed, weight, and wether you can maintain a constant speed all have alot to do with the mileage you get.

I just put my second tank of diesel in yesterday since I bought the truck. First tank was 14 mpg not towing anything with 50/50 highway and town driving CC set at around 67 on hwy, and trying to stay out of the throttle when in town, kinda hard to do while getting accustomed to that 6.0 power. Second tank yesterday hand figured to 16.4 mpg with about 80% hwy miles CC set at 67-70 mph. (of course I also had to take it to dealer yesterday cuz it was puking oil and coolant out of the coolant overflow tank LOL) thats the way it goes I guess. I am going to drive it 450-500 miles all highway one of these days on a road trip and post what I get then. Also, the second tank suffered my foot in the throttle a little more (still lovin that turbo spooling up and feeling like a rocket ship taking off).

Keeping your foot out of it is indeed a problem. Commuting to work(16 miles 1 way) I try to stay under 2000rpm, and coast on the down sides of the foothills I drive through. I make it a contest to get the MPG readout as high as possible for each leg I drive. I usually average around 16 city mpg.

I just got back from a short trip and was very pleased to see 18.6 overall. I just went over 15.5K hope it might get a bit better but I am pleased to say the least.

Just got back from a 3372 mile round trip towing a 7000# trailer. All but about 400 miles were with the trailer on.
.
Average MPG for whole trip = 12
Best Tank = 19 (without trailer for most of tank)
Worst Tank = 9 (pulling through traffic then over the Sierra's)
All hand calculated, running whatever fuel I could find, cheap (of course cheap being a relative term).
.
Also keep in mind that once I was out of Calif (speed limit is 55) the states I was in had a speed limit of 70 or 75, which I did. I am sure if I had slowed down, the MPG would have gone up significantly. If anyone is familiar with California, northern Nevada, Utah, Colorado, New Mexico and Northern Arizona you will also know that there are LOTS of hills and some are a good pull. Full range of 10,640 foot elevation to below sea level. This is all bone stock. Great Truck, excellent puller, no complaints with MPG unless someone can figure out a way that it will make its own fuel.

I've got a 06 F350 CC 4x4, 20" wheels, 3.73 LS and bully dog triple dog programmer. i usually run on extreme with smooth shift settings.
i usually average 15 in the city, 16-18 on the hwy doing about 70-75 mph
11 pulling a 6000lb trailer, doing 65 mph on the highway, and that's on tow/economy setting or just stock to keep the egt's down.
this required alot of patience, but i was able to get 26 mpg average over a whole tank doing about 53 mph, and that was unloaded.
i've recently upgraded my stock exhaust and air intake so i'll see how things go from now on..but its too soon to tell.

These trucks do get good mileage. There seems to be a couple things in common with the guys that claim they cant. They either have lifts and non-stock tires or drive at 75+mph. I have an overall avg of 18.72 (mixed U.S. MPG) over the life of the truck.

Has anyone tried one of those after market..after tranny bolt on overdrives? My thought has been if your can get a 7th gear for use on the highway...where you don't need all that torque for trailer pulling, then maybe the rpm could be down in the 1500 range, thus lower fuel consumption. I see the overdrives advertised in different truck and diesel truck magazines. Just a thought about getting better fuel mileage.

I just made an unloaded trip also. I got 20.6 on the way there doing 63 mostly and just a light crosswind for the most part. I got 19.0 on the way back but had a pretty good headwind. Highway mileage is good, it's around town and towing that it doesn't do as well as my 96 did.
