Ok, so I figured I would start a thread with my different MPG numbers for the new truck.
I run a dedicated lane, 4,500lbs down and empty back in a J&L Dry Bulk tank for roughly 2,700 miles round trip. My route never changes and it goes as follows:
Westville, IN (US421 to I-94 to I-57) to Tuscola, IL. Then from there I take I-57 to I-55, I-40, I-30 to Texarkana then AR549 to US71, I-220, I-20 to US79 to US59 thru Houston to Victoria then TX185 to Seadrift.
On my 1st trip this week I set my cruise at 1,350rpm which put me at 67mph. I got fuel and avg 7.2mpg for the trip down.
On the way back, i set my cruise at 1,250rpm which was 62mph and I avg 7.85mpg.
Next week i am going to set it at the 1,250rpm down loaded and see if it makes a difference with the 4,500lbs in the tank, which i doubt it will, but ya never know.
