Can we get a fuel mileage thread going.

I'm looking at getting a diesel F350 or F450.

Empty and/or loaded

 

Please specify what year and which engine has your interest.

 

If I can swing it I'll get a new one, but otherwise, something no older than 2010.
Crew cab.
DRW.
most likely automatic.
possibly 4WD.

I know the towing weight issue is very subjective as is terrain, but if I could just get an idea of what to expect (empty and/or with some kind of a trailer load), that would be great.

 

2004 f-350 6.0/6spd. Stock, 169K mi, 21mpg highway.

 

I'd check the diesel forums for this info. This area wont get you the most diesel specific info.

 

There has to be 10 of these threads going at any point in time on FTE.
