How's your mileage?

[wjpatton]

After almost 20 years w/ 1st gen truck and 20 mpg on the freeway at 75+ mph (B250, auto 2 wheel drive) I traded for the new 6. 7 B3500 dually, 2 wheel drive and 6 speed auto. The truck is an awesome improvement in every way, but I'm more than a bit disappointed with the fuel mileage with only 7K on the truck. 65 mph, cruise on nets 16. 5 mpg on the flatlands of Arizona. In town is noticebly less (11 mpg or so) and I'm a pretty conservative driver. Am I missing something?

No mileage sucks in these trucks I am only getting around 15-16 mpg wifes 05 is getting 20mpg I think it has somthing to do with all the emission crap on these engines and it going into regen every 50 miles I just installed my gauges and every day on my way home it goes into regeneration mode and the egts go up to 1300 degrees. EPA sucks lets make a truck that is burning cleaner

but!!! burns twice as much fuel this does not make any sense to me.

Here is a simple answer... ... ... ..... BAD.

 

[GMorency]

I sure don,t know to many who are honest that can say they get big milage with any drw truck. 16. 5 isn,t that bad not much worse than my 02 drw was. My 90 2500 only got 20mpg and it wasn,t a drw or quad cab and a LOT less power then throw this weak fuel into the mix and your not doing bad.

I have been getting 13 and change around town, which did not worry me too much as it is down 2 mpg from my '05. However, last weekend it did not improve at all driving Tucson to Phoenix and back on the highway. 13 mpg unloaded on the highway is insane.

 

[Simplysmn]

With my 08 I am seeing 14 -16 in town and on road yes I drive it like I stole it but I am seeing 15-16 on freeway that is with less then 5000 miles on it .

I don't know about anyone else, but I can't justify buying a brand new truck. Aside from the instant depreciation as soon as it leaves the dealer lot, the mileage on the newer trucks from what I've heard on here is just horrible. My 90 doesn't owe me a thing and I consistently get 22-23 mpg going to and from college, obviously driving like a normal human being. I just don't see a newer vehicle in my future unless I hit another moose, which brings up another point: These older trucks are honest to god freight trains. Last march I hit a moose at ~ 55mph. I'm driving back to school in Vt, around a slight corner to get on to rt 107 on the hammer and there it is. Put the brakes on and right before impact she tries to back up, slips, and drops her shoulder into the center of my bumper, her hips hit the driver side of my bumper and she disappears from sight. I pull over immediately, get out, and there's nothing behind me but skid marks and blood. I look over the guard rail, nothing... I'm starting to get a little worried, because If this thing is still alive it's probably not in the best of moods. Then I walk back to my truck and look under the dana 60 and there she is. Just a hunka moose. I go to the front of the truck expecting total destruction and to my disbelief only a bent bumper and a kinked fender. All lights in tact, grille's good, hood perfect. I get in the truck and drive down the road to call the cops, they come and the first words out of the statey's mouth is "Holy ****!". He put the weight between 800 and 1000lbs. I actually drove that truck for the rest of the school year until rust got the best of her. It's just another reason why I will never drive anything but a truck. If I had a car I know I wouldn't be here to write this.

Speaking of honest, I wonder how honest my brother-in-law is when he tells me that me that he gets 21 mpg on his new 08 Ford Super Duty with the 6. 4 PowerJoke empty on the Interstate going 70 mph.

 

[PaulBarker]

Guys are you kidding me, as the yrs go by and technology comes out, this is the best we can do. 2 mpg less than my old truck is bull crapp. if i was getting 18 in a 04. 5, i shouldnt be getting 16 in a 07 truck. thats as$ backwards. at the worst it should 18 if not 20 mpg. i hate to see people roll over and say it could be worst. i am doing something about it my self. the DPF is coming off next, the EPA can go to hell. again thank you H & S for the new system!!!!!!

if your brother-in-law told you he is getting 21mpg than i bet he is cheating on your sister cause he is full of it:-laf



there is no way in hell, i have a few friends that have the new powerjoke 6. 4 and pray for the day of 15mpg on the highway.

i,ve got just over 15,000 miles now. hand calc and overhead are pretty close +- . 2 MPG on the freeway (I5 or 101) at 65mph I get 19-21. 5. at 75-80 mph it drops to around 16 mpg. most of my driving is on the hwy but around town the mpg drops to aroun 13.

the first 10,000 miles I never showed much above 17 mpg.



At about 4,000 miles i took a 6,000 mile trip towing my TT at about 8,000 Lbs.



Ever since then the MPG seems to be better.

I did have the REV A reflash done just before the trip towing the TT.

I have not yet had any more recent reflash done.



I do however notice that if I reset the overhead on a long trip rnning down the Freeway the MPG will show 20. 5 at 65 MPH then drop suddenly as low as 14 mpg. then it will after 15 or 20 minutes start creeping back up.



I assume this has something to do with regen. I thought that running at freeway speeds would be enough to have a passive regen event, but maybe I'd have to be pulling a load to create enough heat to keep her from going into active regen cycle.



Hmmm getting off topic but my mileage does seem to have improved with use.



Later,



Mike

I am not seeing it happen! Around town if you "drive it like you stole it" you are right there with me at about 10 mpg! the fwy mpg sounds close though. :{

 

[Garlic]

On my 07. 5 I am getting 15 -16 on Hand calc. I have nothing to complain about. The Gasser got 10 on a good day, a bad day I've seen less than 4.

 

[GMorency]

If you read that artical on regen its not an issue on the highway maybe take it in and they will tell you something real stupid.

I believe that some people think that the best way to increase your fuel mileage is to lie about it.

 

[GMorency]

Did you ever hear the one I did good I went from Detroit to Lakeland on $300 so how many miles to mpg is that, I don,t know how do you check that.

 

[Jeepstang]

I get 11-14 around town and 15-18 on the hwy these are with an empty truck!

I have11,153 trouble free miles on my truck now. (No computer flashes done yet) We just returned to Ca from a 5956 mile (GPS) trip to Memphis Tn with stops in Co, KS, OK towing a 10,000 lb high profile 5er.

Total trip MPG =10. 9 mpg

4900 miles towing =10. 33 mpg

1049 miles non towing = 15. 0 mpg

Avg $2. 99 per gal, all ULSD

fuel milage

My milage has been pretty good. I have an 05 4x4 crew cab. TST. FASS 95gpm. Modified the stock air box and Banks charge air cooler and big head intake. If I run on level 1 or 2 @ 70 to 72 mph. I have seen as good as 25mpg avg. But it's usually right around 22mpg. When we got hit with the ultra low sulfur I had a 2mpg loss no matter what I did.
