I can tell you that 57 is too slow for anyone trying to slwo down that is used to 70 mph. Try 63 or so first for a couple weeks.

Start driving by your boost gauge too. Limit the torque so that you only ever get 20 or so lbs max up the hills. You will also find your cruise control is your enemy when doing this. it will give the truck too much boost and power at even the slightest incline, instead of letting it fall off a miles/hour or so.

Lastly,, the engine may need some serious tune-up work/maint. and other stuff too. Most truck owners neglect their equipment badly, then go into panic mode when there is a check engine light, etc... instead of actually keeping after things that are known to lower fuel mileage and cause problems.

Lets see,.. If I owned a T700 with a CM2250,.. reefer freight, 48 states, mostly heavy,. Stock I could easily push 7 - 7.5 mpg out of it at 63~ish if engine/sensors was in decent shape,... MM'd at 57-60~ish,... long term 8+ or higher with the occasional fill-up above 9 mpg.

It is not easy to do but the reward is the education and mindset of driving for high profitability is where you benefit long term. What your goal should be is driving that way until it becomes your normal driving style.

Once it is your new normal, and you actually start enjoying going a bit slower, having less stress,have better time management, etc. eventually you will not even like going faster. This is where you want to be so that you can start focusing on other things,.. and look towards getting your own truck. This time around though, doing so with much better understanding on how to make it successful with a decent long term profit that you can keep.

I don't know about anyone else,.. but I like having a house and truck that that is completely paid for. I did NOT have to run like a bat out of hell and killing myself to get to that point in life. -- It simply takes a bit of long term discipline of ones self instead.
