Deuce Fuel Mileage

[cbvet]

FYI:
My non-turbo deuce averages 5 mpg traveling at 55mph.
Adding desplined hubs gave me 6.5 mpg.
Desplined hubs & 45 mph gave me 8.7 mpg.
I will be traveling slower from now on!

I was getting 7-8 from TX to GA pulling M105 loaded down.

 

[Ferroequinologist]

I got about 10 coming home from Aberdeen last may with a pretty loaded truck and M105.

 

[m-35tom]

trips have always given me 10 mpg regardless of the truck @ 55 mph

 

[Westech]

I got 10 to and from Aberdeen (2,000 miles) at 63 mph and towing my M1008 behind me.

I've seen a lot of posts the last couple of years from people getting much better mileage than I do.
Why?
My truck starts & runs fine. IP appears sealed like originally done.
I've done fuel filters & air filter. What's left that can affect mileage that much?

My non-turbo deuce

That may just be the difference. Most here have turbos.

fuel. I run very heavy fuel, ATF and such. You get more BTU's in a gallon of heavy fuel then lighter Diesel or Gas. Other things could be brake adjustment. I Keep mine very loose to keep drag down as much as I can.

Westy...what ratio are you using?

 

[Bill W]

Driving from Virginia to So.Fla About 10mpg with the 8000lb purification body on the back ( avatar ) 52mph/2350rpm's, LDTA21C

The number one job of a turbo is fuel savings. The HP increase is a side effect. If a turbo isn't in your future make sure the toe in on the front axle is set. This will bring drag down alot! I have found most of our duece fire trucks had the toe in set way off. Also make sure yor running max tire pressure in all ten tires. This doesen't sound like much but when you have ten tires scrubbing unstead of four then it adds up. You might also try some lucas injector cleaner. I've had great luck with it. It might clean up your spray pattern. I have lockouts and a airshift. I run all ten tires at 65PSI and try to keep it at 45MPH. And run 50MPH rarely. With short bursts to 55MPH only when nessary. I get 13mpg. But my turbo isn't close to stock anymore and i have ported and polished every intake/exaust runner i can get to. I'm adding a universal K&N strait to the turbo this weekend and see if that helps any also.

So Ken...when did you say you could polish my turbo too? I can make you some goat cheese from my goat milk in return lol

 

[alphadeltaromeo]

Another question Ken...the ride on 65lbs...give me your thoughts pre-65lbs and post...and what was pre anyway?

 

[Westech]

80% or more or ATF, Motor oil, heating oil, ect...

 

[alphadeltaromeo]

Let me understand this westy...you run only 20% diesel and 80% of filtered other stuff?

 

[OPCOM]

averaged 8.86 on 2800 mile road trip last year. ftont lockouts, S-280 shelter in bed, 50-55MPH.

 

[Westech]

yup she runs like a champ... really smokes

Turbo with no racks or canvas. 10-12 mpg. Pulling a trailer really knocks it down to about 8 mpg. Keeping it under 50, 45-48 seems to really help too. Did a 1250 mile round trip unloaded down there and loaded back 9.5 mpg. average. I call it keeping your foot out of the accelerator. But then sometime I just need to hear the C-turbo whistle....

 

[devilman96]

Ditto on heavy fuel... I can tell a big diffrence in HP when Im running heavy v/s light (diesel only).

 

[alphadeltaromeo]

What do you consider a big difference then...10% gain or more? What ratio do you run dman and of what?
