Fredvon4, yes I am the fellow with the dump and heavy plow. I have run about 4 tanks thru my truck since I have had the hubs unlocked and plowed any snow, and to my supprise the first two tanks of fuel with the hubs unlocked netted worst mpg than with them locked plowing! the last two have not been to bad, around 8. which I consider acceptable for a 9600lb truck. Something else kind of funny on the second to last tank of fuel I have gotten I hauled a couple good loads with it and I actuall got 8.3 mpg. The last tank was 7.8 with no loads. By the way thanks for your awnser to my above posted question.

 

Fred, on page 12 of the 36 page Ford guide "What's New for 2005", there is mention of a gas tank delete option, listing 30.5/38.0 capacitys (I have it as a PDF, if you'd like a copy). IIRC, I also saw another reference to that figure more recently. I also posted yesterday in the superduty forum about this and my recent calculations in this regard.

Just trying to keep things consistant.

I don't think there is enought diff from 29 to 30.5 to get my hackles up over and I should have worded my earlier post differently and not sound so frustrated over a piddly 1.5 gallons

You mean this:

So what part of Fords stuff is the real deal..hell I don't know. I don't have the huevos to run any of mine to the piont that it is all the way empty and try to see how much I can stuff back in. The most I ever pumped into the 01 29 Gal SB was 27 gallons and so far the most in the 05 38 LB has been 34 gasllons.

 

fred,
On the contrary, it is us SB owners who are frustrated by a mere 1.5 gallons! (actually that's a 5% difference, statistically significant)
I'm wondering if 30.5 is the actual capacity of the SB tanks (including reserve), and 29 is the consumer-safe marketing capacity.
Of course the real problem here, [is that] I have so much fun with this truck, that I'm customer of the month at my local Shell station!

 

We just picked up a new E-350 last Sunday after waiting about 12 weeks. I was very happy a few nights ago when I filled the tank and got 13.8 mpg. We got the Chateau model with the v-10 and a 4.10 RA ratio. We have only driven on relatively flat country, kept the speed to 65 and below and have not towed our TT yet. It has been very nice to drive, even in 30+mph winds, probably due to the weight of 6500# plus me and my wife. The v-10 seems to be a very quiet and smooth engine.

Good luck,

Froggy/Dentureman

 

i really dont care

 

And sir we all are done giving you lots of good free advice...have a good life and I hope some day soon you trade in that V10 beautiful SuperDuty truck on a VW TDI and get the 47mpg your need to be happy. At least your SuperDuty then could get into the hands of a true believer. Someone who can appreciate a BSEG every day.

 

My 2000 F250 Crew Cab V-10 automatic 3.73 axle got 15.5 mpg @ 70 mph no load. I wonder what a 2005 V-10 4.10 axle 6 speed would do???

the way you act. you sound like the i'm never happy person that drives us mechanics crazy. if you don't like your truck sell it and leave us truthfull old timers alone. your feeding a tight motor and a 10 piston one. go buy a chevy 3500 with a 6.0 and see what you get.

 

First 700 miles on my 05 CC 4x2 4.10 SB is averaging 12.5 unloaded with mountains, city and highway combined. I can't complain since my Lightning got 13-14 unloaded and it weighed a lot less.

 

Odo turned 2800 miles today; 8.85 mpg. The best I have gotten yet!!! Hope the mpg keeps climbing!!

 

I have faith in the posters on this forum. The info that I aquired from this forum helped me build my Superduty and everything I have read have come true thus far. Granted there's always one standout in the crowd. Now at 800 miles (See Sig) I have an average of 9.5mpg since new in primarily all around town driving with mixed loads in real world traffic conditions. I can only expect it to get better with time. Maybe another 2-3mpg. My previous daily driver a 1997 C-1500 5.0 2WD only got around 15mpg and wasn't nearly half as fun to drive. And My Plow truck GMC V-3500 DRW Stake body never averaged more then 9mpg on a good day. This truck replaced both and is twice as fun to drive. It's an unfortunate reality that the price of energy will probably never go down.

 

guy up the street from me has a chevy 3500 with the 6.0 gets 7 mpg all the time and people have the gall to complain about 10 with a new 6.8 v10 in here. the dodge i dumped had a 4.7 v 8 and only got the same as my v10. and it was a dakota 4x4

 

captchas mu father has 03 dakota quad cab 4x4 4.7 vs 23000miles 17.1 on the highway 13.5 to 14 in town not stella for a small motor and small truck but if your dakota only got 7 something is really wrong or your making this up and by the way i ride with afriend with a 2500 cc 4.4 6.0 4.10s 31575r16 mudders powerprogrammer 60 miles to work once a week we gpsdhis truck to make sure spedo is correct it is his lifetime average on the computer is 11.8 his best 16.5 and i tell you it is a strong running truck no i wont get rid of mine or buy a vw diesel like fredvon said but i dont understand how you all are getting such great mileage and im not and afew others arent either i dont thinkit will do no better even if i have 30000 miles on because after6 other ford vehicles i havent noticed maybe but maybe .5 mpg after it has broke in this is my experience with my vehicle
