LIGHT VS HEAVY LOAD AND FUEL MILEAGE
 
Has anyone computed fuel mileage on same truck, on same route, once hauling light, say 22000lbs, then hauling heavy, say 44000lbs. I know there is a savings I just dont know and havent computed the savings. I hope someone can save me some time.

i do it almost every trip, i deadheaded 151 miles from greensboro NC to Covington VA took NC68 to 220N right into covington, avgd 7.2 mpg hauled 42300 paper load same route back to gboro and avgd 5.9

Well i can contribute to this post by posting some money figures as well.

When i run out of Charlotte, N.C. i 99% of the time go straight to Chicago( HYW 74/40/75/74/65/80-90 ). Ill stop and fuel in Gary,I.N. at that Flyin-J since i start out full from Charlotte(or near full).....diffrence between the lighter load(25 to even 35000) and those thay weigh more like bricks or whatnot is about 130$. Thats as close i got to understanding how a heavy load acctualy affects the buttom line so i try and stay away as much as i can. When booking a load a carefully examine where its going, how heavy it is and make my decision accordingly, sometimes it pays good but when computing the numbers it can acctualy hurt more that help..

It depends on terrain you run. In a mountains, it will be around 1mpg difference, on a flat, just about 0.3mpg.

Solo it is definitely more then that. Problem is, even every trailer is a bit different. But back in my 'run' days going from winnipeg to minneapolis, I paid a lot of attention to fuel mileage. A full load was easily 1 mpg less then a light load.

Wind alone can make more difference to fuel mileage than weight. I remember getting 8 mpg one way, then 6 mpg the other way.

Detroit to Newark 1 mpg difference between 15k and 40k

Yes, i agree. But i was talking on the all other things, being equal.
Or at least, it's how it's in my experience. :roll:

Thanks for the replies. I am thinking about targeting some shippers with foam and insulation loads and would like to get away from hauling 44-50K of steel and sticks. 1 mpg fuel savings is good enough for me if I can get the shippers to pay a decent rate and fsc. Thanks again.

My 2001 Peterbilt with a 500 Cat and a 13spd (if that matters) would get 7+ mpg at 75 mph while hauling 12,000 and under pound loads. The same truck would get less than 5 mpg hauling 40k loads at the same speed, slowing it down to 64mph would keep me at a 6mpg average with those heavy loads. This was running from CA to VA via 80 each week.

Hope this helps ya.

5.6 in a w900 doing 75 and always close to the limit, I get around 7 when i`m running empty.
