2010 terrible mpg
 

Can anyone tell me why I shouldn't have bought the 5.4 or V10? This diesel gets around 10 mpg and my old 5.4 got 12 13 and the fuel was cheaper! I need a way to get better economy mpg because this just sucks I thought diesels were better on fuel than this - O and yes it does have waaaaaaaaaaaaaaayyyyyyyyyyy more power but still. :dang:

my 2008 f450 6.4 diesel crewcab 4x4 auto with 60,000 miles gets 12.5 hooked up to trailer or empty. its 12.5 mpg all the time. its got a k and n intake only.

my 2009 f350 V-10 gas reg cab 4x4 auto with 15,000 miles with cakebox/haybed at best gets 9 mpg highway. 5 mpg when checking/feeding cows, All stock


Both trucks are amazing in comfort and in how beefd up they are in power and in towing performance. But both are horrible in fuel catch 22

you gotta think tho they can do better than that mine is at 10.1 mpg in town and 13 on highway at 70 with cruise:scare2:

on the 6.4 u will have to delete the dpf, but then it wont pass emissions when u have to go thru in 5yrs or whatever and u will have to buy a programmer so u dont get a chech engine light

Gee, my '09 Duramax/Allison gets 15.5 mpg around town and 22 mpg at highway speeds. What gives with the Fords?

I am also pretty upset with the MPG's

I have a 2010 and am getting the same numbers you are.

In Illinois they dont test Deisel Emissions so taking the DPF off seems like a good move.

Question for both of us? If we take the DPF off and then have to get the truck serviced,
is Ford going to flip out or will we have to put the darned thing back on before taking
it to Ford? Also, will a tuner be needed? :argh:

Thanks! :c:

It's really ashame the 6.4 don't get better mpg without voiding the warranty or not being able to pass emissions. They have a lot of power and run really good just eat you up on fuel when left stock.

It's funny how the parts they're using to produce better emissions, also kill the fuel economy.

Do like everyone else, get the programmer and the DPF delete and enjoy 17+mpg with your truck and a ton more power. I know if I had a 6.4 it'd have this done.

Put the DPF back on for dealer visits and emissions testing if you have to do so.

Looks like you're lucky. Sounds like some of the other LMM drivers are close to what the Fords are. They will always be better (or should be) since they're a much lighter truck anyways.

Delete the DPF and EGR, and throw a tuner on her and she'll get way better mileage, some guys say they're getting 27+ on the interstate, I usually go ahead and subtract 10 from numbers like that, but 17 mpg in a fullsize pickup of any kind or engine isn't bad at all

Removing the DPF and EGR can't void the warranty.

Why not? It says right in the owners manual (even in my 6.0) that ANY modification using non Ford parts can void your warranty. Ford is covering their own a$$.

Well hell i have a 91.5 12v with the pump maxed out and i still get 18 mpg around town. But it is a dodge after all.But if i were u i would go ahead and take off the DPF and EGR. but thats just me.

Then compare what your Dodge weighs next to an F450 crewcab dually.... I bet the Ford weighs just a WEEE bit more, and has more power to boot. Not to mention no existence of any emissions control on your vehicle what so ever.

it's like we're comparing apples to oranges, the only similarities is they're both a fruit and relatively round in shape, the 12v should get better mileage, it's lighter for one, and it has no emissions equipment, whereas the 6.4 is heavy and has a terribly restrictive exhaust system and egr, and the dodge dealer where i live voided the warranty on my pickup because i had a lift kit, they didn't even know it had a programmer on it, so now that I have no warranty I figured I might as well have a set of 40" tires and a Goerend transmission

Listen to Bobcat67. He and i were just having the conversation about the emissions on the 6.4's yesterday. I would be glad to give anyone a run down on what all i had to do to get 23.7 HAND CALCULATED MPG on the highway. Seriously, 6.4's are amazing trucks and i will NEVER get rid of my 2010. I will send pms to you guys and please answer them, ill help you love your trucks as much as i love mine.

Jared, I tried IM you but I dont have enough posts so I dont think you got it.

Please email me at bassincity@hotmail.com

Thanks!

I havent did it yet, but im gonna do a dpf delete and run with a spartan tuner. Just have to stick the dpf on before going in to the dealership:c:

just delete the dpf, put a sct touch srceen or live wire on it with eric from Innovative diesel! i did and i get 23+ mpg on high way and 17-18 in city

MPG's are slowly increasing. I have less than 2,000 miles on the clock but now seeing 14 MPG's. Hopefully that number will rise. :tu:

I was lookin at the spartan tuner again today. 1,300 bucks and then also havin to buy the delete pipe. I really want to get this ordered up.... I need to buy a house first though:argh:

Tell me I just bought an 08 and ready to do something to it already:tu:

I know it's easy to tell you to spend the money now since I'm on this side of the computer, but you gotta think, the sooner you get the DPF deleted and the truck tuned, the sooner you get better mileage, and the more your return on investment...:pca1:

I agree
 

I loved my 7.3. It came time to upgrade so I purchased an 09 F250 Crew Lariat with the 6.4. Drop dead gorgeous truck. Two tone Blue/tan. Rides way better than my 2000. Interior is beautiful. Re-design of the F250 was a home run. Motor is smooth, quiet and quick. Then comes the mileage. 10-12 in town, maybe sneak up to 13-14 on the highway. Please don't answer back with "Power"...or "you bought a puller, didn't you?". By any standards this is unacceptable and really kills what is an otherwise awesome machine. The truck is good enough that i will live with the mileage. But constantly filling up more frequently than one should is getting pricey and annoying.
"Just remove the DPF, and tune it !!!"
Correct me if i'm wrong...I thought a law was passed years ago that prohibited dealers from refusing warranty simply because a vehicle had been modified. I thought they had to prove that the particular mod was directly related to the failure before they could refuse warranty.
That being said...I am pretty sure the DPF is different. It is an EPA mandate and Illegal to remove. It may be the only mod that the dealer can refuse warranty...no questions asked?
"Just put it back on when you take it in".
Thats fine and this may be the direction I go. What concerns me is the intended use of these trucks. I would say that most of us spend a fair amount of time pulling on the open road. I'm on the interstate 600 miles from home, or on vacation, etc, and my truck goes down. Replacing the DPF on the road away from home so i can get it towed into a dealer for service work seems unrealistic. I might anyway as the improvement seems huge. Just replacing the DPF might not always be possible before one 's truck goes into the dealer.

Hollow out the DPF, this way its still on but you cant tell anything was done to it. The best of both worlds..

This is a old race car tuner trick thats done with Mustangs and other stockers. Just hollow out the cat with a big drill bit. :tu:

has any one on here actually done this on a newer truck

If you hollow out the DPF,:td: your trurk will go to limp mode !!! You'll lose power & you'll have to go to the dealer & DISH-OUT lots of $$$

You must run a tuner that deletes the DPF.

I dont see a way around it, even if you hollowed the DPF out, and you did have to take the truck to the dealer under warranty, you would have to put it back to stock tune
and then the truck wont run right anyway according to Gunman41mag.

I guess the only way this would work is for people with no warranty and are worried about not having the DPF in place. If I had no warranty to worry about, I would hollow it out and get a tuner. Diesel engines are exempt from emission testing in the state I live in.

IF you have a TUNER, then you could remove the DPF !!! But BLOODSPORT wanted to hollow out the DPF with-out a tuner :scare2:!!! THAT WOULD CAUSE PROBLEMS, & once you take it to the dealer, the dealer will find out what you did. MAKE SURE YOU DO YOUR HOMEWORK so you don't lose your WARRENTY !!!

What DPf delete kit would you guys recomend?? I was looking into spartan or Sct live wire but don't know, there are so many of them out there would like to know what ones have been proven by by people first hand!!!

I have 6.0, looking at 6.4
 

i currently have a 05, 6.0 with 81000. Have had no problems until now, replaced pcm last month and is now in shop for egr problems. I don't trust this truck any longer, especially since warranty end in two weeks. Last night looked at a new 2010 6.4. Kind of angry at Ford thinking about GMC. What do you think.

2003 F-350, 7.3L, Air-intake/chipped and beefed-up transmission. :c:

I joined the diesel bombers forum today just to comment on this thread. I have an 08 f250 with a spartan tuner running the 250hp tune. As for removing the DPF the tuner is what fools the computer into thinking its still there after you remove it. IF you take it off or hollow it out or whatever without tuning the truck it will go into a constant regen and your mileage will get worse.

As for mileage after the spartan I dont believe anyone who says thety are getting 23mpg out of a 6.4 Its a plain and simple lie. Now what i do know is that a lot of people are going off what the display on the dash is saying they are getting as opposed to hald calculated mileage numbers.

Before i tuned my truck i was getting 10mpg in town and about 14 on the highway. After installing the spartan 250hp tuner, AFE intake and DPF delete i get almost 13 in town and about 17 on the hwy. I do know that spartan owners who run the 275hp tune do tend to get better mileage than the people who run the 250 or lower tunes. :rocking:

I hope this helps clarify how the spartan tuner or even the SCT tune will help you. If it were mine to do all over again i would def choose the spartan over anything out there. The support is awesome and the power and mileage gains are simply unmatched!!!

Have you actually read it? If you had, you'd know it doesn't say anything of the sort.

i have a supperchips raceing programer,and a dpf delete and my truck does some crazy things power wise since i added over 200hp. It also says that it get 27 mpg running down the hwy but idk wat it gets on paper. i keep my dpf in my toolbox incase i need to put it back on for warenty work. 2010 f-350 4 door long bed 4x4

anyone read the picture of the modifications tag that ForcedInduction has shown above. Is it just me, or does it seem like it reads that Ford will not cover warranty failures if they are related to an aftermarket mod, but will cover failures of the EPA emmisions products (even if related to a mod). Meaning regardless of the situation, the DPF is to be covered under warranty as it is essential to clean emmissions.
