What mileage should I expect from this van? My old van was a 1 ton Chevy with the GM diesel and with the same load got 13-14 mpg. The Ford only gets around 9-10 mpg. Is something possibly wrong?

 

Mine gets 14-15 around town w/o going too light on the go pedal, 17-18 freeway/long trips, again w/o easy driving. Have noticed that the cruise control relly does work well and increases mileage.

 

oh yeah, weighs 7500 every day, w/o load on rear platform.

 

Thanks for the info. What should I look for as the cause for the poor mileage? Any ideas?

 

The owner's manual suggests replacing the fuel filter if you notice poor mileage. If you don't have an owner's manual they can be downloaded free at Ford's website.

 

I bought my 2001 E350 Superduty Cube Van with duallys in the winter just a month ago. I am getting 10mpg. But like I say, Its Winter, Its a Dually, Its a Superduty, Its a cubevan and it weighs 10k with my tools in it, and has 160k on the odo. Im pretty happy. Even though my IDI got 13mpg

 

My non turbo 6.9L IDI motorhome (11,000 pounds) with a 3 speed transmission gets 11-12mpg cruise control @ 60mph on a nice flat highway. It does have highway gears tho, 3.54

That PS van might have a really low geared rear end to have that kind of mpg, or somethings wrong. Maybe just in need of a tune up.

What's the mileage on it?

 

2000 E350 superduty extended PSD gets right around 14 MPG combined city/highway and 17 straight highway with a 4.10 rear end and stock tires..75000 mi.

I've had the van only 10 months and not totally familiar with it yet but my mileage has slowly increased with the mods I've learned here...from 12 to 14 MPG average city/hiway.

 

Get taller tires if you do a lot of hwy driving, it really helps.
265/75-16 BFG AT, 2WD, SRW, E350 Extended 7.3 PSD = up to 22.5 mpg. average about 19-20mpg hwy.
Towing a 7000lb TT, cargo inside van 1200lb and I still get 13-15 towing.

All done at posted speed limits.

 

I have almost new tires but I checked into going to the 265's. I've have personally had poor experiences with BFG with poor bonding between the plys. Whenever I got a puncture and put in a plug, I got a bubble 100% of the time. Haven't used BFG in almost 15 years.

 

E-350 Super Duty 6.0 Power Stroke 2006:
I ordered this van new. I asked what size gear in the rear end and they said 411, I asked for a higher gear and they said 456, I smiled and said other way..the highest I could get from factory was 323 with limited slip and 5 speed trans. Truck will pull a house down plenty of power if you know how to use the transmission.
Under 50 mph I usually come out of overdrive (rear end will growl a bit) but not a big deal.
I get 19.3 MPG/diesel, but could never get 20 mpg, with a factory style cartridge K&N filter. Drops down to 16 MPG when hauling my trailers (8000 lbs or heavier)
Van empty, scales at 10056 lbs..heavy van for sure.
Installed E-Con Hypertech/ Max Energy-#43005, and up to 23.5 MPG now !!(don't care about the X-tra power but it is nice)
Next and last step I am looking into 4-5" straight exhaust, I have not researched it yet, any feedback would be appreciated...
...moral of this story is high geared rear ends will save MPG..

 

I recently purchased a 1994 E350 15pass clubwagon with a 7.3 powerstroke . lots of miles on it. 370,000ish km. around 230,000miles?

it runs great now that I replaced the cam/crank sensor.
1st tank I calculated got me 20.2 mpg . (our gallon is 4.54 lires/US is 3.78 litres). combinedhighway and city , and it has 10ply 245/75/16 snows on it.
I am putting a set of bridgestone rib tread 215/85/16s on this week and might go with a 6" rim on the front with them instead of the stock 7" rim.
better mileage is my goal!
filled up 2nd tank yesterday but can't find my calculator.
it will definitely hold more than 100litres and it looks like an 800+km range.

I'm looking for better, I figured it would get between 22 and 24.

from my research this van should not have a powerstroke in it, but it does?

I'm looking into a chip/programmer for milage improvements as it is our main family vehicle now and I hope it will be for a long time.
I've always wanted a diesel clubwagon, and the more I drive it the more I like it! wife loves it and so do the kids

update: 2nd tank was 22.0 mpg thats more like it

 

I have a 2000 E350 extended cargo. Just got back from a 2800 mile trip, and I averaged a bit over 20. Some tanks went as high as 23 and as low as 18. Pretty happy with that.
