does anyone else get better milage with a ton or two on thier truck than empty my 600 just got 19.9mpg with 2 tons of potatoes on it but when Iran home empty I only got 19.1. Same roads mostly U.S. 20 a hilly road up this way I'm guessing aerodynamic drag or wheel hop any thoughts?

 

Nope.

Ummm, you drove the entire trip downhill with the load of potatoes?

I know our trucks run good, but in no way will it get better mileage weighing an additional ton or two.

What are you basing these numbers on? The overhead computer readout, or filling up at a station, with a few hundred miles on each tank? None of the above?

Be glad you've got a good one.

 

Funny....I had about 1500 pounds of firewood in my truck and was getting about 17.5 MPG. That is the same as empty. I was judging this by the overhead but it seemed a little strange to me.

 

I've noticed that on our work trucks the mileage is almost the same with a loaded or empty trailer. Granted they are big trucks. I think that it has a lot more to do with wind resistance than anything else.

 

Towing my 5500 pound Travel Trailer on lost about 2 MPG.
Also noticed MPG improving daily. Really getting better since started towing my Trailer too.

 

filled up after i unloaded hand calc. 19.9 filled up after I got home running unloaded hand calc. 19.1. My 99 got about the same empty or loaded but this discrepency seems pretty large.

 

I forgot but the trip was about 300 miles each way

 

Spudman, you know you will always get more high carb energy with potatoe power.

 

Potatoe

 

prevailing wind, grade rise, opposite coming back. With the big truck I used to get almost a mile less a gallon from Birmingham to Wyoming than coming back.

 

Oh!!! you meant when the TRUCK is loaded!

 

well there were a few beers in there but I was all good to go
