E350 mileage?
What kind of mileage can I expect (in the real world) from a 2001 E350 Super Duty w/ 5.4L. I'm not sure what my axle is ... how do I tell?

Hmmm... I bought my '03 E350 a little over a month ago, but it's been too cold to crawl under it (except for an oil change...) to verify what the gearing is. I can tell you that I'm getting 14 +/- 1 MPG out of my v10 combined city/country.

I have to say the more that I read about the V10 in terms of mileage, the more impressed I am. My 91 5.8EFI with a 3.55 and the E4OD consistently gets 14mpg, no matter where I drive it, highway or city. Most people on this board are commenting how they can get 14 mpg on the highway, slightly lower in the city. I'm starting to think that the horsepower vs. mileage is leaning more towards the V10...maybe it is more a question of aerodynamics or lack of aerodynamics....

I would LOVE to get 14 MPG with combined driving. Just not going to happen for me. 10 is the magic number at the fuel pumps. On the highway we can reach the lower to mid teens, but when running at 70-75 it's drops to about 12. My old 351C engine always got 10 MPG no matter what. As for getting a V8 vs. the V10, V10 all the way. Power is a lot better and rivals any diesel on the market.

Adventure what is your ride? I may know of some ways to get your mileage up.. I need, the year, model, engine, trans, rear end, and how many miles it has on it.

That 3.73 rear end is what is killing your milage.... What if any mods have you done? You could try a cool blue or k&n filter, bump your timing up as little to around 12btdc, and get your o2 sensors checked. They can tell you how the engine is running..... When did you last change the plugs and wires? These may all sound like small things but all it takes is one plug to not fire at full capacity to drop your mileage 2 or 3 mpg. Most of the people here are getting 12 in town and around 15 on the road... That is in the 15 pass club wagons...

This is stock all the way. The mileage now is identical to the mileage when we first got in '99. As for the rear end, 3.73 is better than the 4.10 and a 3.53 would lower the towing capacity too much for my needs. There are no "wires" on a V10, thay are all coil on plug so you don't have the typical high resistance wiring issues found on the V8 from the distributor. As for plugs, they are original and I don't have any intentions on changing them soom, too many folks end up with a plug blow out after changing them on the '99 V10's. Thanks for the suggestions. Oh, and mine is the extended version, 15 Passenger, best all around vehicle I've every owned. It can tow anything, haul anything with the seats removed, and still carry the kids at the end of the day.

I get 10mpg at about 70-75mph loaded with two racebikes and gear (about 1000lbs). I get about 10mpg in the city with one person and no gear. I pretty much get 10mpg no matter what I do.

I drive an'01 E-350 with the 5.4 and 4.10 axle, haul ALOT of weight (plumber) and get no more than 11mpg. This is my 4th 350 since '86 and the milege has always been in the 9-12 mpg range. BTW, this van eats rear pads.

mileage
I have a 2002 van with a 4.6. I just installed a Flowmaster muffler and got 21 mpg on the highway. I did everything were supposed to do to get mileage. You know. Drive reasonable speeds. [60 mph] Accelerate slowly. That kind of stuff. I have to admit that it worked. However, local driving I only get about 13 to 14. With a 460 you're probably not going to do much better.
