2nd Gen Non-Engine/Transmission New to diesel is this about right..

my 98 with a 96 12v, stock o/d transmission and 4x4 3500 gets 15 MPG up hill down hill, loaded not loaded. 15MPG period all interstate driving. Uses no oil, does'nt smoke, starts like a champ, everything just peachy. Don't want to tweak anything if this is normal gas mileage. Thanks.

What gears do you have? Do you drive like you stole it?

mine gets 18 plus or minus 1mpg around town , and 20 plus or minus 1 on the road. got 17. 9 last week around town. towing it gets 11 mpg hauling a 8k tractor and a 6k trailer and a golf cart about 1k . has dropped about 1mpg over the last 250k maybe time to have it timed and new injectors ( i'm still on the originals)

Mine is all over the place. Long trip, freeway 21mpg. Trips to town 16 to 18mpg. Pasture 12mpg. Loaded with 10 ton of hay 9mpg. A head or side wind is tough on mileage too.

Thanks for the quick reply. Considering I'm a little less younger than GOD I do drive the speed limit only. I haul my tractors at my farm in Missouri and don't notice any change + or -. The truck is fantastic starts one touch at O or 100 degrees, Just wish I could up it a few MPG's. Oh also the engine only has about 3000 miles since rebuilt .
