My 6.0 gets good mileage for the way I use it, alot of towing and I live in hilly terrain, the truck is stock for now and I'd like to do some mods some time, it doesn't change more than 3mpg at the most no matter where or what I tow.

Mine is bone stock and gets 10.7 in town, 8 while towing and 12 on highway unloaded.

[polarbear]

On average, city, highway, offroad and towing aprox. 12 mpg.  Modifications are 6" RCD lift, 285 BFG, Cat Back Dual Exhaust, K&N, 160 degree thermostat, Hypertech Programmer III, Mag-hytech Transmission Pan

I've seen as low as 7.5 and as high as 15 mpg's on my 6.0L.  Not bad for a 6000+ lb 4wd truck!!!

Mine is 02 k2500 8600gvw and was getting a flat 10mpg until they overhauled the trans at 3200 miles and gave me over drive! Now its pretty consistant at 13-13.5mpg. 3.73's.

Did anyone notice a difference once their truck was broken-in?  I'm getting 12.4 right now but I bet I would get a lot better if I could stay off of the gas in the city.  But I like hearing this thing run!

Mine is actually still getting better and I now have almost 7500 miles on it.  And I have the same problem too...  A heavy foot in town!!!  It's fun when you are sitting beside a kid in a 6 cyl Mustang or something similar and easily pull away from him when the light turns green.  My truck normally is shifting at 2500 to 3000 RPM.

Oh...   also its a 6.0L and 4x4

[Kelly]

I'm getting 14.1 MPG.

Average 60 miles total to & from work every day, 70% highway & 30% city.

2002 2500HD 6.0 is still as is from factory, no engine or tire mods, but plan some in near future.

I have gotten 8 to 10 pulling my trailers 6000-7500 lbs. Got 11.something one time .Daily use city and interstste I get 12-13. I ran it one time on a 200 mile trip empty and got solid 17. This was using cruise at 60 mph trying to get good MPG.   You can get decent MPG if you try.

I get around 12.5mpg in town and towing 3000lb boat (3rd gear and tow haul mode). I like the look on other drivers faces when I pass them going uphill in the hammer lane when towing the boat. I have gotten 17mpg on one leg of a 450 mile highway trip (not towing) with the cruise on 70mph. Average highway mileage is 16mpg. My only beef with the truck is the small gas tank. My previous trucks were longbeds with 35 gallon tanks. I have put 25 gallons in the 26 gallon tank and the warning light was not on! Does anyone know if there is a reserve for the gas tank?
