I posted this on the 6.0L forum earlier today.

I need to buy another truck. My 2007 F-250 was stolen yesterday. I pull a 24' fifth wheel travel trailer and the 6.0L has been just fine.
I've heard that the newer diesel engines get poor milage and are prone to problems. Is this true? Do I want to stick with 2007 or a little older or should I go ahead and get a newer truck?

Thanks
Ed

 

the 6.4s drink heavily...

the new 6.7s seem to be pretty amazing.. see the 6.7 section here.

many 250/350 srw reports of 18-20mpg stock (not towing)

Ed,
I love my 6.4 although Sam is correct they love to eat diesel mainly because of the dpf. I got 9-10 towing a 9-10 thousand pound box trailer. I know that if you remove the dpf and tune that he mpg's go up to 13-15. The problem then is you take the chnace of voiding the warranty.

08 job 1 trucks were prone to problems. The 6.4 is a good motor and it will pull and haul all day long. As you may already know maintenance is the key to the 6.4 oil changes every 5,000 and fuel filters every 10,000.
Hope some of this helps you out. Good luck!

 

yep, I get about 9mpg towing a 20ft car hauler box trailer.
12.5 on normal driving and 14.5 on the highway empty..
(all at 70mph).. my 6.4 is a dually with 4.11 rear gears.

that 9mpg is 50% better than my 08 suburban hauling the same trailer over the same roads!..

seems the 2011/6.7s drws (3.73 rear) are getting 12ish hauling same weight, and 17-18 empty.
the SRWs 3.31/3.55 are the better mileage beasts.

good news is as you pile on more wt the mpgs don't change much. I can get 7-9 pulling my high proflile 5er.

I can get 17 empty hwy runs.

I think I get better than some for two reasons. First and primary is my break in and use.

At 600 miles I already had 10K behind her on a 600 mile run to Boston, MA and back.

Secondly I have the 6-gun from Banks on it. I think that helps to refine the programming. It is a clean tune do DPF is still there.

 

Thanks Guys, I feel better about getting a newer truck now. I felt a little uncomfortable having to Pigeon Hole into a 2007. I was under the impression that the 6.0L was more "Bulletproof". From what I've been reading today it's six of one ... half a dozen of the other.

Thanks
Ed

 

That stinks your truck was stolen!!

I was wondering the same thing when looking for truck, I was stuck on 06/07 for a while but then I really wanted the newer interior-just so much more up-to-date. I then found a late/job3 08' and went for it! Ive put 12,000km on it since I got it late oct and its been great. (New batteries, heat shield, and a rubber oring in lower rad hose fixed, under warranty)

 

If you were happy with a 6.0 in terms of reliability, you'd really be happy with a 6.4. I have a job 1 '08. I don't think it's been overly problematic. Sure it's had a couple minor bugs to it, but nothing huge.

As to oil changes, filters, etc. I go a little contrary to the flow. Use an oil analysis program to determine correct change interval on your engine oil. '08s and later require a CJ-4 oil, something your 6.0 did not. Using the analysis program and Archer Gold 15W-40, I'm at 7500 miles between changes and could stretch that if I wanted to. I change fuel filters every 15,000 miles. Unless I'm on a trip, I use premium diesel fuel rather than #2. If I can find it I use it on trips as well but can't count on finding it easily when in unfamiliar locations. #2 is common at truck stops, etc. Some will have both grades.

God bless your search! I'm sure whatever you find will be something you'll enjoy other than maybe fuel economy on the 6.4s.

 

How can you tell if you are getting premium fuel? I don't see a #1 or #2 on my local pumps

 

Here locally there is a sign that will say premium diesel. Different pumps then the regular diesel.

 

when I was in Michigan I saw premium and regular diesel. i ran both and didn't get better mileage with either one. around home here, they don't even offer premium.(which is just fine with me after that experience)

 

I buy locally from a supplier that only offers premium or a winter blend thereof.

Believe me after 40 years of diesel experience, even if you don't see a difference in mileage you will pay a premium for #2 - one way or another.

Some ways it'll cost you are:

• shorter fuel filter change intervals
• shorter service life on injectors
• shorter life on fuel sytem in general
• more foreign material in fuel
• dirtier cloudier looking fuel
• more moisture intrusion
• higher cloud and gel points
• less lubricity

 

As far as Shells 'premium' vs 'regular' diesel the only difference is they add additives at the station.

 

It's not a true premium if they do that, although I'm sure it helps. . The one I know that is is Cenex Roadmaster XL.

 

I would like to point out that "premium" fuel is ALWAYS either #1 or #2, depending on climate.

It's like comparing "premium" gas to "unleaded". Premium is STILL unleaded, but not all unleaded is "premium".

It's not?

I'm pretty confident that the only separation between "premium" and "regular" is the additive package. This can be a meaningful difference though, as that additive package will increase cetane as well as lubricity.

These claims are remarkably similar to the claims made by reputable additive companies. When I'm at a station that sells premium diesel and regular diesel, I ALWAYS pick the regular stuff and treat it myself. I don't know exactly what additives they use, but I know what I use and am confident of it's effectiveness.

I seem to get better fuel economy on the regular diesel treated with Power Service than I do the "premium" stuff. I have also run the regular treated stuff in temps as low as -25 degrees with no gelling or performance issues.
