2017/18 MPG

If you're averaging low 6's and driving 70-75 mph, I think that's pretty good. Maybe try 62 and see what you get. I know that's not your question but that's pretty decent mileage at that speed.

I have a 2016 Volvo with a D13 motor set at 455 hp. I-Shift transmission. Run the west coast only. OR/WA to CA & back. Heavy loads down, lighter loads back when I can. 60 mph for the most part. My current avg is 7.61 mpg.

I have a friend who bought a new KW T-680 recently. He runs flatbed CO, MT, ID. NM, etc. He's averaging around 6.5 mpg.

 

2003 Volvo N14, 1.2 mil without inframe, 13 speed, 3.42 rears, general dry van freight 5-40klb, average 6.7-7.3 driving 65-70mph
Best I had was 9mpg in Summer running from MI to Denver, 10klb doing 70mph the whole way

 

If you can buy a truck that get 18 mpg , get it writing from the dealer.
6 to 8 is about all you can expect in the real world.

 

I think he meant mpg averages for 2017/2018 trucks.

 

That's good milage for that speed.
I have a '12 Cascadia / Van and that's about what I get. ISX 450.
5 MPH slower will give you an extra .5 mile to the gallon.
Your rear end ratio is a factor as well.

 

2007 w900 ,isx @550 hp,13 speed,336 rears,70-80k lbs,50k miles on rebuild and skateboard @ last quarter ifta was 7.04 mpg going 66mph

 

2018 International LT with A26 motor, 10spd direct, 6x2, run reefer 68k gross and higher, mainly East of The Mississippi, at 8.8 MPG so far. I was doing good until the past 5 days when I got into a lot of weather.

Price difference between this truck and a Glider was 8k. I'm glad I went with new. I've been very impressed with it.
