Diesel mileage

I was wondering what kind of fuel mileage E-350 owners are getting with the Powerstroke diesel. Especially compared to the gas engines (5.4 V8 or 6.8 V10

This is research for a college class, any input is greatly appreciated.

City or highway and a good guess on how much of each (in %) and the usual load carried ( empty, half-load, full-load)

Thanks in advance!

From my post in the "f-series" forum

"We own over 30 units with the Power Stroke enigne, both 7.3L (from '94 to '03) and the new 6.0L.

The 7.3L engines typically get 14-16 MPG in city pick-up and delivery, light to medium loads, but stop and go driving (and they are in a HURRY). The 6.0s are about 1-2 MPG less, but offer WAY more power.

Now, our shop's service van weighs in around 13,000#, yup you read that right. It gets 12.5 MPG average for the year, and it does a LOT of ideling especially in the winter. Most of it's trips are under 5 miles as well.

Our salesman has a 2002 F-350 4X4 Crew cab w/ class V trailer tow package (gearing), he gets CONSISTANTLY 17-18 MPG empty, and 13-14 towing his race trailer filled with car and gear.

A co-worker has a 6.0L, he gets 14-15 empty, and 11-12 towing a 33' gooseneck loaded or empty. But, it GOES LIKE STINK."

I also heard from another dissapointed Duramax owner today. He reported only 9-11 MPG towing a lightly loaded goose-neck trailer. That's the second person to report very poor mileage with them to me personally. Both of these people keep fairly accurate records as well.

I have no data on the van gas engines as we do not own any (thankfully).

Thanks for the reply. I have to "sell" a product for a class on selling and I will be pitching the Dodge (Freightliner) Sprinter van against the Ford and Chevy full-size vans. The fuel mileage with the Sprinter appears to be excellent, most testimonials I've read talk of 20+ mpg averages with a half load.

So I wanted to use MPG as a selling point, but as you know, fuel mileage for 1.5 ton vehicles doesn't exist. I needed some real world info.

Much the same my post is under f-series titled 6.0L Powerstroke (Engineering Blunder). I have a 2005 E-350 loaded with power everything windows all around, forged aluminum wheels and all the chrome I could get. The van is used for a 24 hr locksmith vehicle so it does a fair amount of idling to power the 2000 watt invertor,key machines and power tools. The van was shipped with a bad #8 injector and a cracked turbocharger. I have 12000 kms and can honestly say the van has spent more time in the shop than on the road. The foul smelling emissions not present in alot of todays diesels with higher emission standards forces me to turn the van off in residential neighbourhoods where I spend much of my day. Fords cannot come up with anything but the cetane story I've posted because the engine light never comes on to pinpoint the problem. Fords tell me that I leave the van running for far to long but this is why I spent 7000 more to get the diesel because they stay cooler when idling. I am also getting about 12-14 mpg with about 1000 lbs of cargo at any given time. I also pull a utility trailer when delivering safes and the power is good and I know the mileage will improve when the engine breaks in but because of this engineering blunder if I had it to do again I would go with the Dodge sprinter even though new to the market and not much to look at.
