Given the fact that chevy's weight 1000 lbs less and have 2" shorter tires they better get more MPG than the heavier Ford. Funny thing is when you lift a chevy to get the ride height of a Ford and put 33-35" tall tires on them they get worse fuel mileage than the Fords do and the are still 1000lbs less....

 

Don't mean to be rude "But if Chevy is so much better then get one and go to that forum. I for one are sick of hearing about Chevy..Now I have nothing against Chevy. I have owned a few...Both have things I like and things I don't like...But you do not see me here bit$)ing about or see me on the Chevy boards telling them how great Ford is or what they can do better than Chevy...

Whew...Now I feel better!

 

Ok. Now lets see....

Most mileage: GM ?? you forgot to mention this # there buddy
Most 5th-wheel towing: Ford 24500
Most conventional towing: Ford 16000
Most payload: Ford 6120
Most GCWR: Ford 33000
Most GVWR: Ford 14500
Most front GAWR: Ford 6500

Sounds like GM's building a "green" truck, while Ford's got the whole work thing down. Ford builds their truck to work. If the weighed the same a GM they would get the same mpg. I think with these numbers I can live with the extra 1000 lbs and a mile less per gallon.

 

Hey SouthTexasDiesel, nice combo you have there. 350DRW 3.73's with a 6 speed. How do you like towing with it. Miss my Standard and 3.73's sometimes. Good points you brought up too.

 

Hey now don't share this but
"I've got a friend who has a brother of his sister who runs around with a guy who knows a person that works for my brother who fired his best friend who said he was getting 30 mpg out of his Mack Truck"

 

I thought it was the forth cousin twice removed and once separated that fired the brother of the second cousin...

 

Man
I got so confused I forgot that!
Thanks

 

Towing is great with this beast. My normal load is about 10K of feed and it brings it up to speed in no time and has no trouble staying in overdrive. I decided on the 3.73's for the mpg and it turned out great. Gettin 17-19 mpg at 63-70 mph empty.

 

big rigs always do that

 

Amen, man. But as one person who did the same thing with a dmax and with a Ford SD, it really didn't matter about the weight, as my 6.0 get's the same mpg as my Dmax did. But wait, the FORD came with factory 18s (vs steel 16s), and sidesteps, and 1400# more gvwr, and bigger brakes, and a stouter front drive/front end (SFA vs. IFS), and an integrated brake controller, and, oh-my-gawd: it doesn't overheat like the dmax, due to the puny radiator the dmax had (they still are far smaller than the equivallent Ford). Did I mention the butt ugly clearance lights? I could go on, but, the Chevy is a poser, built for racing or something (certainly NOT looks), but not anywhere in this universe of trucks is it close to a Ford. BTW: the msrp between my dmax and my Ford were within a hundred bucks, what a basic piece of crap they build for those looking for a 1 ton srw -- go look for yourself...

and look at us 6.0 guys defendin' the faith...!

Never, Never, going back to the pos underdesigned Chevy. Been there, tried that, and it's not even close to all that...

good posts Enomra...

 

I am reporting back again, a trip from san diego to san felipe mexico towing my 15k pound toyhauler I made sur to slow down just to see if I get better MPG so going there I kept my speed at 65 MPH I got 8 MPG coming back I batteld some some head winds and speed at 70 MPH and all I got was 6.5 MPG now I have to say I had a lot of headwind and I was empty 14k pound at most because I had no water no gas in the fuel station and propably no more than 10 gallon in the generator tank so slowing down your speed does help a lot.
now let me comment about the trip I do not care what you guys say but the truck when I stoped for refueling in el centro and I did not turn off the engine because of 110 degree heat to keep the A/C on for the kids but I soon as I put it in park it went to regen 1250 rpm so the next one someone tells me that my truck will not do that because it was hot from towing and the heat generated from the stress of towing the trailer will not go to regen then he is going to be insulted from me in this web site because this the segond time that this happened to me the first time was going up the grade about two month ago right in the the middle the speed dropped and the I felt I lost half of the power and now this trip as soon as pulled to refuel it did it. please do not ever think that you truck will not go to regen when it is working hard as it will it does not care and the fact that someone commented before that there is no way it will go to regen while working hard is false false false this the segond experience for me so I do not care wheather your are pulling 20k pound or going up 20 mile 10% grade the fact that truck is working hard very hard does not mean it is burning the soot in the cats and when the computer tell it clean up it will, not caring what the hell you are doing.
I have now 7600 miles on my truck and I still believe that I made a mistake buying this truck and the trailer because a gas motorhome will give you almost the same MPG without the headeach we are having to refuel with the ULSD which is very hard to find.
in Calexico (border crossing town) to mexicali there is propably 25 gas station and only one that has the sticker of ULSD on it and only one that you have to find with the trailer behind you stop and go stop and go until we found it.
I think that getting 6 to 8 MPG towing is not good and please do not come and tell me if you can not afford it why did you buy this truck as I do make XXXk a year and the reason I stating this it is because the agravation that you have to stop to refuel every 200 miles because you do not know when you will find ULSD sticker on the pumps and I do not think that a truck pulling a toyhauler should get this low MPG towing and to make the story interesting finding the ULSD adds spice to the story.
I have stated my income so people know it is not about afording the gas or the vacations or the truck MPGs or the stopping every 250 miles for refueling but it is the agravation I am getting from this truck I think I am intiteld to at least 10MPG pulling my trailer with a diesel engine.
I say this but the truck pulls like it shoud I do not think what hill you will point it to it will climb pulling the trailer there is no slowing or lack of power that we had with the gas motorhome.
another thing I need to add I met this guy in san felipe with 2005 quad cab duramax he was pulling loaded 7000 toyhauler and he got 11.8 MPG going there by doing the math I do not think MPG are that far off between chevy and ford so stop tell us you have a friend that gets 20MPG with his duramax towing 15k pound that is bunch BS as the guy I talk to does not now me and has no reason to lie to me.
Another thing that happenned is as I was going thru the border someone shoulder hit the passenger turn signal and it brooke a call today to the Ford dealer told me it is on backorder until june the 13th and they do not when it will be available the computer says so do not go craching you new trucks just yet guys because ther in no parts availble for them yet.

 

Tell him FORDSINCE76 some of us here are business people we do not give a sxxx what brand it is ford chevy dodge I could care less we have a job to do and we bought the truck to do it for me it was selling the gas motorhome and buying a toyhauler and the truck to pull it with.
by the way we had 98 ford expedition eddybower when they first came out and we trade it three years later for a Z71 suburban and I have to say I did it because the chevy towed much better and was more sur footed than the ford we got a way better MPGs and back when we did it we did not do it because of MPGs we did not even pay attention to MPGs until we started driving it but we did it because when it was windy the expedition was not safe at all especially towing a trailer with toys in it and that is because it has a shorter wheel base not because chevy is better.
you know I lived here for 20 years and like in France there is people that are very loyal to a brand on the other hand we business people anywhere france usa china we do not care what brand it is we buy it because it is the capable thing to do the job that I have to do.

 

Good info to know, since the 6.4 is so new to us all. I believe the feeling was, we were speculating that it would not go into regen towing as hard as you are. You are proving that the soot still accumulates even under hard towing conditions, that it still need the extra heat from the regen to burn it off. Most of us have not had that experience yet. We will be towing 13,000 over the next couple of weeks through Pa & Virginia so I will watch for the Regen to see how it compares. Sorry to hear about your fuel mileage with 3.73’s sure hoped it would be better. Let you know how my 450 with 4.30’s does. So far with some short local towing and combined city, rural driving have averaged 11.53 hand calculated. Hoping yours is the exception to lower than expected towing fuel milage. Its good to see that some people can give honest mpg under certain conditions so we can all continue to learn.

 

drisschoufa,

I find it strange that you are only getting 8 MPG pulling a 15k fiver with 3.73's. I have a dually with 4.10's and pull a little less weight, but I get 10 MPG going basically the same route as you, I head for Glamis instead. On that flat piece of desert between the mountains and El Centro, the trip computer tells me I'm getting in the mid 11's.

What do you get on the highway empty? For me I get 13.5 MPG at 70 MPH.

Also, and please don't take this as an insult or me questioning your account, but I've never experienced a regen while towing and I pulled 1,000 miles between San Diego and the Grand Canyon along I-40 and there are some pretty good grades heading into Kingman, AZ. But as I understand the regen process, exhaust heat incinerates the soot and, according to the Ford Diesel Supplement, highway driving should be sufficient enough to keep the exhaust temps high enough for a passive regen.

This is quite interesting that there is such variability in people's experiences with the 6.4. For me, I love the truck and am very happy with my purchase, decent towing mileage, no problems towing, though I do agree with drisschoufa, it can be a chore looking for ULSD on roadtrips. (Some of the small towns you go to have not sold enough of the new #2 to certify their current inventory as ULSD.) Pkus drisschoufa and others here says they're getting poor mileage and regen's at what I would say are weird times.

Are there any Ford mechancis that read this such a Vloney, that can explain this variability to us diesel newbies?

FYI, my rig has just over 5k miles and just had it's first oil change.

 

I am no diesel mech, however I will tell you without a doubt, the 6.xx engine is the most sensitive to driving conditions and driving styles I have ever seen.... out of any type of transportation…..EVER.

I can easily get 16.9 at 75 all day long, if I vary the slightest amount the way I decelerate and accelerate I can drop it 2/4mpg across the board.
