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
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.
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
