M923a2 estimated fuel mileage?

5tonman1971 · Jan 2, 2014

Well I may have just won a m923a2 with the 6atc 8.3l cummins and I was just wondering what the fuel mileage is like on these trucks. If I win it (fingers crossed) I'll have 550 mile drive ahead of me. New castle Delaware to Cairo, Ohio.

Also if anyone is along the way and could possible give me a hand if needed that would be great aswell.

wish me luck guys!

Figure 6 MPG (depending on speed) and anything better is gravy. With the super singles you can bust 65 MPH but you'll suck fuel. My M927A gets optimum mileage at around 56-58 MPH which is about 1900 RPM.

Keeping the RPM's under 2000 some people get 10-12 depending on the truck.... at 2100-2200 they get in the 8ish on a good day..

I think with a M923a2 you will see about 7-10mpg going around 55mph with out any payload or to many big hills.
My m923A1 gets about 7-8mpg and I am thinking the A2's get a little better mpg.

Have a safe trip and be sure to do all the safety checks and check all the fluids.

When people ask me what kind of fuel mileage I get with any of the trucks I change the subject so I don't have to think about it. Maybe you will get lucky and have the first full tank on Uncle.

Even on the best day the MPG will suck. I look at it as the cost of doing business. With that in mind, I'm already stocking up on discounted gas cards when Publix has them $10 off. I saved $80 last year using them going to the GA Rally. [thumbzup]

8 to 10mpg is about average. If you can keep it it 50, you'll probably see 11 or 12 mpg.

Think of it this way:
The truck weighs 32,000 lbs (at GVWR) and gets 9 mpg. (288,000 lb/miles per gallon of fuel)
A Prius weighs about 3,900 (at GVWR) and gets 55 mpg. (214,500 lb/miles per gallon of fuel)

It's more efficient than a Prius!

The way I look at the mileage is when you need fuel is fill it and for get it. You need the fuel to get from one point to the next. If you want fuel mileage is to get something else.

WOW all the MPG numbers you guys are giving are sure a fair bit better than my 925A1 gets and that is on its BEST day!

My m813 gets 10 mpg with the 16.00 so these all sound about right. Thanks guys!

You have the NHC250 (non turbo). It's size and design are less efficient. If you look at the TM (TM 9-2320-272-10, page 1-22) , you'll see that the M939 and M939A1 (which you have) are listed at 3 to 4 mpg. The M939A2, with it's 8.3 Liter turbo engine, is listed at 5.5 to 6 mpg. These are likely cross country numbers, not highway.

Based on this info, I'd imagine you get about 5.2 to 6.6 mpg, correct? (66% of the A2's 8 to 10 mpg)

It's like non-science!

Would it not be non-math? lol and should we discount 1to2% because of the Krappy fuel we get now and the better fuel when the trucks/ figures were put out? Just kidding so don't get mad it's early morning and after three days of rain I see the Sun and get to play with MV's Cheer up all as miliage may verry.

I'm not afraid of sharks, especially when I'm hiking.

If I was you, I would be HAPYY with WHAT EVER mpg you get, as long as you DO NOT own a wrecker, my m819 (loaded or empty) gets a touch over 3 mpg, though fiying through the air increases the mpg dramatically.

LOL, My M936 gets about 4-5mpg on a good day.

My 816 gets I don't worry about it just put fuel in have fun doing job.

wreckerman893 · Jan 3, 2014

Buying an MV for fuel mileage is like eating chocolate cake to lose weight. A vehicle with the aerodynamics of a concrete block is never going to be a fuel sipper. My O-ring puckers up every time I pump fuel into the M927 but dayum she looks good going down the road.

My HET gets at least 20-25 smiles per gallon.
