Fuel efficiency...

Lift one axle and dump the air from the other.
Much less friction and wear on the tires too.

 

Okay dngrous_dime, here are some articles that you can reference:

www.OverdriveOnline.com/smart-driving-22
and maybe for flatbed drivers

While they may not be specifically what you had im mind, maybe they will give you some general help.

 

In the heavy haul world fuel efficiency goes out the stack

That DD16 I ran last year was doing good at 3.8 - 4 mpg. Being of the O/O mindset,. I kept track of it. Carrier said dont worry about it. No idle restrictions. Fuel was not even on board as a concern. Back of my mind I was like,.. But? But?,... But what about,..??

For me and my current model, fuel mileage is very important. On certain low rate loads,.. making up for the loss of rate with better fuel mileage from a light load often evens things out when doing the math at the end.

My wife said it best,.. "You have to pick and choose your battles out there".

Mpg is an art. Over 700 hp, hauling heavy and I can get a better average than a boy with 550 hp can get. But like pass said it isn't really much of a concern with what I do. It is how you use it.

 

Yes I do try to watch my fuel mileage some what. But with a dead apu and not really taking the time to install a better one. My idle fuel kills me

 

When I first got this truck,. I idled all the time. I honestly did not know how much fuel was costing me to idle.

I knew it was hurting me but not knowing the true amount sort of left me with that ignorance is bliss mentality.

Last year when I put the generator in here and started to cut back and minimize my idle time, it really threw me for a loop to see how much my weekly fuel expenses went down and how my MPG increased in the truck. On average I save $300 a week from not idling last year. This year with lower fuel prices,.. its about $175 a week. When fuel prices go back up is where I will really make out. Figure I work about 40 - 42 weeks a year,.. $300x 40 weeks is roughly $12,000 that stayed in my pocket. That little $2000 generator has paid for itself over and over.
