2008 F350 Diesel Fuel Mileage?

[Anthony]

Well, looking at "up-grading" from out 2008 F150 to a 2008 F350 Diesel.
Can somebody tell me what their fuel mileage is with their 2008 F350 Diesel?
I looked on the web, but not too many reviews to find this info!

Thanks Crew.

My 08F350 when pulling a trailer gets around 12mpg and about 14mpg any other times, I have 39000 km on it. Not to happy with the mileage. Lots of power though.

For more go to Fuel Mileage - Diesel Forum - The Diesel Stop.com

Ouch, Nearly as bad, or equally as bad as a Gas Job.

Just did the same thing myself. Sold my 2008 FX4 F-150 for a 2008 SD 6" lift FX4 -350 extreme. right now with 76 hours on my truck Im reading 21 litres per 100 ltr.
Now as the difference. I drive all over the city at times 200-300k in city. but on a normal week per say. I drive aprox 100 k per day in city. old truck cost $145 to fill and last for day -day in half. SD costs aprox 130 to fill and last three in a bit days same driving in the city. Tested in out soon as I got it to see what the difference is. Hope that helps a bit.

Towing I get 12-13 mpg. In town and highway combined with only the quads and sled on is 14 mpg. Highway with only quads and deck is 15-16 mpg. Highway empty is 16-17.5. Trying to conserve fuel on the highway I have gotten 17.6-17.9 consistantly. The best I got with a strong tail wind, only the sled deck, 108kmh is 18.8 mpg (boost stayed between 6 and 10 psi). The worse i got is 6.5mpg with sled deck, two quads, pulling my travel trailer into an 60kmh head wind while driving at 120kmh ( boost never dropped below 35 psi and 50% of the time it was dropped out of overdrive). My truck only sees WOT when passing and towing.

Mine is a Job 3 with factory ride height and tires/wheels, running 3.73 gearing, no chip or tuner. My truck is scaling in at 9000+ pounds full of fuel and sled deck on. I have 10000kms on mine.

For every 3 psi of boost you loose 1mpg
For every inch you lift the truck you loose 1mpg. This includes lifts and tires. Use a Job 2 or 3 air dam if you have a Job 1 to gain 2mpg.
Sled deck alone or a tonneau cover will increase milage by 1mpg.
Cetane booster works if fuel at the pumps is less than 43. BTW cetane at PetroPass's fluctuates greatly (35 to 43).
Regens cost you 2-3mpg for 10 to 30 minutes. Regens are avoided with high egt, but high egt are created with sustained high boost so it's a catch 22.

If milage is a concern or you idle alot forget any of the 08+ diesels, look for a low milage '07. Friends with 08 f350 all get worse milage than me, but all are lifted with 35-40" tires. Friends with '08 Cummins and Duramaxs all get the same or worse as me under similar circunstances.

F350 gas unit leaves you with only two options. No towing power in the V8 or 8-12 mpg all the time with the V10.

The Diesel Shop link Ron gave you has lots of info on milage, but also read about DPFs while your there. DPF delete kits with tuners are seeing 20-22 (some claiming 25) mpg in US gallons; Gains like this are worth killing the engine warrenty at some point.

I have An 08 Superduty, Completly Stock.I Took It In For The 15000km Check And Asked The Guy's At Hansen Ford Is The Fuel milage Going To Get Better. He had Told me That At 30000km It Will Be Broke In And Fuel Milage Would Improve. My Reply Was it may Never See 30000 km I Can't Afford To Drive it. But Now it Has 31000km And The Average Is 16-17 mpg. Only If I Keep The Foot Out Of It. Pulling The Holiday Trailer 12-13mpg. Can Not Complain About The Ride And The handling For A 1 Ton Its A Beautiful Truck To Be Behind The Wheel At. If Only The Fuel Milage Would Get Better. Heard A Rumor That FSJ Ford Was Covering The Waranty On Engines That Guy's Who Had Cut Out the DPF. If This Could Only Be Truu ?

With regards to the Warranty I wouldn't touch anything, there all watching for issues relating with modifications. I know peeps at Ford and Dodge dealers and they do know that you have a chip, even if you remove it and ride for a bit. If you want a chip for your new ford I have one for sale, because I dont want to take that risk. I do really like the truck though, its beefy and it pulls the big trailers way better than any truck I ever towed with.

I was looking to upgrade to an 2008 as well but, decided to keep my 2006 for the mileage issue alone. I have a CC dulley 4x4 with 4:10 gears and a Bullydog programer and get between 20-22mpg. ( around 16mpg pulling my trailer) My local Ford dealer even admits they are having problems with the 2008`s due to all the new emissions laws. Although they would love to sell me a new truck they told me I was better off sticking with my 2006 for another year or two if I was at all concerned with mileage.

Ron how many k do you get per tank?

 

[ZIG]

08 f350 supercab short box with 3.73 job #1. Now that i have 20000km i am now getting 18.5 mpg= 15 litres per 100k. I am driving 30km a day to work doing 100km maybe 105km. Before i got to 20000km i would only get 16mpg. I have tried fords cetane boost it makes no difference. When i pull my 21ft enclosed sled trailer i get 13mpg. There is also an update for those leaking rads it is tee fitting ask for 8c3z 8b379 b.

I haven't heard of anyone who is happy with their mileage in an '08 SD. Most I've talked to run them for work and don't pay for fuel.

I get 15 US.( 18 CDN ) mostly city in my 07 Classic Duramax. 35's, about 410 rwhp.

Best trucks for mileage seems to be '03 Cummins and duramax. Emissions controls have steadily decayed mileage since then.

You must drive like a total white man. I can baby my truck and drive nice and I have not seen better than 14 mpg and pulling my 26ft enclosed Im lucky to get 9mpg if I lock the cruise on 100 Kmh.

Leaky rad, My rad was split on the bottom seam and that was because on job 1 they didn't have enough rubber rad supports. (I was told this by the tech, but he could be wrong)

I find it funny everyone crappin' on Fords mileage when no other truck is too much better. My brother in law and friend went to penticton this year, both with 26 foot trailers and 3/4 ton trucks. One has the 2008 Ford and the other is the 2008 dodge. Power wise up hill they said they were pretty even, when they got to the pumps they said the Ford took no more than 10 litres than the Dodge, hardly anything to brag about. As for the chevy in this story, well, its still trying to climb Rogers Pass and the other two have already returned from their trip, a week ago, BUT HECK, them Chevys get good mileage though!!!
