Just about to roll 25k on the ODO.

In the last 2500 miles the fuel economy has noticeably improved. Towed my boat to LBJ and back and got 14 mpg.

Went to Arkansas over the weekend and got 16.5 mpg avg overall (what my ford would have gotten), when i slowed down to 70-72 I would get high 18's.


Ive noticed fuel economy drops when I have a strong headwind or I get above 77 mph. at 80 mph its drinking the diesel even though the rpm's haven't changed much.

Everything else is running just fine.



For it is not the quarry that we truly seek, but the adventure.

My 2024 2500 HD ZR2 Diesel (almost same truck - just Chevy version) just rolled 15k. Mileage is improving. Our speed limits are lower up here so rare to be over 70mph. At 65 to 70 mph my last highway tank unloaded was 21.4 mpg. Combined unloaded i am getting about 17 mpg. Towing i am getting about 13 mpg towing a 12k open float equipment trailer. Towing an enclosed trailer for the atvs and ski-doos at about 2.5k weight i get the same 13 mpg. I believe the lousy milage on the light trailer is because it is wider and taller then the truck and being enclosed it is like pulling a parachute behind the truck. Was the same effect on my previous truck.

Under 2K RPM and the MPG will go way up ... on anything no matter the age or fuel type. My 2003 6.0L Yukon Denali gets 18 MPG at 63 MPH and 13 at 75 MPH.


Pass the gravy.

Did you keep the bigger tires?

The front end replacement and level plus 35's I saw my last two trucks drop about 1-2 mpg

Yes kept the bigger tires, on the lie o meter you are correct it’s showing 31mpg all highway and now 18 mpg highway/city combines. So about minus 1-2 mpg.

Just rolled 30k miles.


In the last 5k miles or so, fuel mileage has dramatically increased. I'm seeing 16-19mpg on the highway now instead of 13-14mpg.

You think it’s the rpm’s that change the mileage, or the increased wind resistance of traveling faster? My thoughts are wind resistance.

I just rolled 11,000 miles, my avg is 19.3, lots of 80mph driving.

Good to hear yours is finally improving

Nuts, 10 speed tranny must make a huge difference. Only time I ever get over 15 is driving back from mountains with a west tail wind. Life time average on my 15 is like 13.5

Yeah the 10 speed is great. Filled up in Vernon and headed east. This was the result of mostly 80mph driving
