Towing fuel mileage/empty fuel mileage

[Larryd1]

I own a 2002 Chevy Duramax 4x4 ext cab 60,000 miles on her and was thinking of trying a new Ford with the 6 liter diesel engine.It is a 4 door 4x4 short box, auto. 3.73, 2500 and was wondering what kind of mileage the Fords are getting towing and empty. I am only thinking about doing this because my Duramax sucks when towing my 8,000 lb. 5 th wheel. I am getting between 10 and 12 mpg no wind ,flat land, I have tried 60 mph up to 75 mph and it still sucks. How are the Fords? I took both the Ford and a couple of Dodges for a cruise today and must say I perfered the Ford. Thanks.

I dunno about the 6.0's but I have a 7.3 and I got 11 mpg towing 55-70 with a 9000 lb trailer behind going up the mountains. unloaded I have seen 16-17.

as of last trip empty,
running 75 ish we achived 15 mpg, which is down 1 from a previous run, (whole nother post)
towing see sig below we run at 11 mpg, 10 if i heavy foot it on acceleration . i try to stay at 70 mph but often i find myself going a bit faster unless i set he cruise.

I have a similar rig to the one you are looking at. Empty, 17-18 mpg average combined city/highway. Towing my 5000# boat, 14 mpg highway. I use Tow Haul mode when towing. Very happy with it.

Looks Good

Thanks for the replies, By what I have been reading it is looking like the 6 liter gets pretty good mileage towing, My Duramax sucks fuel even with my 2,000 lb boat/ trailer and excessories ,this is a 16.5 ft boat with a travel cover and everthing I just got 13.5 mpg at about 60 mph average, no hills.

With my 2006 F350 , 373 gears and 20" tires with a 6liter I came get 18.1 mpg towing my tamdem car trailer, at 75mph but with a 9,000lb load it drops to about 15mpg.

I get about 13-14 mix of pulling 7000lb enclosed cargo/ empty hot rodding, and about 8 pulling 30,000 lb gooseneck

i am surprised you not getting 30 towing, once up to speed you can let off the throttle and use all that momentum to coast

Yeah, If it was all down hill, I'm sure I could
Problem is you would be doing about 90 mile an hour after while

You should probably check your fuel filter on the Duramax. Mine usually gets around 12-14 depending on the how much weight I'm towing, and 18-19 empty mixed city/highway. Mine is a 2002 3500 regular cab 4x4 LB7 with the 6 speed.
