    Looking to see what kind of gas mileage you all are getting with your diesel trucks. Please say the kind of truck and the year truck that it is as well. One of my buddies told me he knew a guy who was getting 20mpg with his 2008 gmc sierra 2500hd. What is everyone else getting?

    Empty in my 95 K2500 I get about 20. With the plow on, 1500 pounds of salt, and the salt spreader, I get about 17. Plowing I get about 15 or 16. Thats with the 6.5 litter turbo diesel that everyone thinks is junk.

    96 Dodge 2500 reg cab auto 4:10 I used to get 16 empty, loaded, city, highway... timing needs to be reset and a few adjustments made to get back there. Plowing would drop to about 14. At highway speed (governed at what amounts to 74mph) Truck could benifit from another overdrive due to the low gears- 3:73 versions get 20 ish and 5spd 3:73 have been regularly reported to hit 24 highway.

    Ol mans 02 F350SD supercab longbed 6 speed (5 plus low) gets about 17 - 18 average driving - never plowed.

    Ill give a few lol. my 95 f-350 cc 4x4 dually with a 5speed would get 16mpg empty and 10-12 towing 10-14k lbs. My 2003 cc shortbox srw 7.3, auto would get 19-21 empty on the highway. My 04 f-350 cc drw auto.would only get about 17mpg empty. My 2009 f-350 cc long box, auto will get almost 20mpg on the highway and 12 towing 11k lbs. All of these trucks were/are custom tuned with exhaust and intake.
    When my little brothers race truck was still a daily driver (06 dodge reg cab 4x4 auto) it had stacked boxes, 90hp injectors compounds ect,ect on 35 inch tires and would pull 23-24mpg on the highway and run 12.1 in the 1/4 mile.

    I get around 10-11 mpg loaded or not, highway. Working, it uses around 7 liters per hour. Not too shabby for 15000lbs.

    My ECSB with the plow on and sander loaded gets 10-12mpg when plowing. Around town empty it gets 16-19mpg depending on time of year/fuel. Towing 7k it gets around 14mpg and towing 11-12k it gets around 10-12mpg. The best mileage was last August going to Maine with stock pizza cutters, fresh oil/fuel filter, tuner cranked up to 120hp and keeping the RPM below 2k i got 23mpg. Most trips it will average 20-21mpg.

    With my 08 Sierra Dmax I can get 20 on a highway trip. As soon as you get in town it drops down to about 15-16 with a light foot.

    My 06 got around 16.5 average, my 11 is getting more like 10-12. Emissions crap kill mileage on the new trucks. I have a 5" turbo back exhaust waiting to go on my truck, just waiting for the programmer and egr delete to come in. I'm expecting an improvement in mileage with everything deleted.

    You should do a write up and post it in the "dodge" section when you figure it out. I am sure a lot of guys will be curious about this...I know I am Thumbs Up.

    I used to average 14 plowing when it was getting 16 regular. This truck would get 16mpg with a full load when I got it - used to spin the tires really easily too.

    12v trucks are known for timing slipping (which according to Cummins doesn't happen - it's pump wear that the re timing people are doing is compensating for).
    I used to do my entire route in 2wd with 800-1000lbs in the bed for traction and get about 14mpg.
    I'm only getting about 14mpg now unloaded, running 4wd to push with 1000lbs in the bed and getting about 11 (well, counting the fuel return line leaking like a sieve the past 2 months I'm getting more like 5mpg) Resetting timing to 15*, changing fuel overflow (to reset fuel pressure), installing fuel pressure gauge and boring out the banjo fittings to while I'm at it should give me a good bit of that back. Probably going to look into replacing the injectors this year too.

    I have a 1989 Dodge Power Ram 250 4x4 with the stock Cummins and I get about 18 empty. Not sure on exact mileage when plowing, but I top it off after every plow outing and I only spend about $25 to do it. A very nice change compared to my Ford gas when I spent about $70 on gas every time.
