Miles Per Gallon?

i get 3.5 to 4.5 loaded 118000 to 132000 lbs 6 empty

 

Hmmm.. The OP has been banned.. I wonder what kind of fuel maximizer he was getting ready to sell us...

 

'06 C15 W900L 4.6mpg 120k permit loads in conestoga
'04 C13 T800 7 mpg legal grain hopper loads
'00 C12 W900 7 mpg legal grain hopper loads
'01 & '02 C15 both W900L's averaged 5.5-6.5 hauling lumber in conestogas making 8 deliveries per day.

I might need a new calculator, everyone knows you can't get over 4mpg in a W9 w/a cat so something must be wrong.

 

I recently figured fuel mileage savings if you go from 5 mpg to 6 mpg with $4 fuel and a 400 mile day you will save $70 per day. That can be over $15,000 in a year. My International 05 9400I was getting 5 and I just traded for a new KW T660 that should get 6.5 and should be 7 and the money saved on fuel will make the payment.

 

math's a little off, but i see what you're getting at. too bad there's too many variables..
