What kind of mileage is everyone getting with their 3500 D-Max Dually? :confused:

Towing MPG
___ - Highway

Non-towing MPG
___ - Intown
___ - Highway

THE BEST I EVER HAD.. was... On flat land and driving 60 MPH I was able to average 20 mpg. Once I hit a few little hills it dropped to just under 19. Seems the Dually's dont get the same mileage as the regular trucks. Then again my truck is a crew cab so it weighs a little more and that hurts mileage as well.

I will load it down with a camper and trailer soon... I am wondering just what the mileage will be as well.

VR :)

I will be on my 4th fill-up today. I have been getting a consistent 14 mpg around town and as good as 18 running 65 on the fwy. I will be doing my first tow tomorrow...38 foot toyhauler with stuff weighs about 14k. I'm hoping to get 10-12mpg towing at 60-70 mph. I will post my results when I get back. Round trip should be about 800 miles. I pulled the trailer home from storage yesterday and was really happy with extra stability the dually gives! I had a 2003 GMC 2500 HD. It had great power, but I was a bit leary of being over-loaded with the big trailer.

My current, personal truck has 6,000miles on it. It shows 17 on the highway, about 14 typical.
I just programmed with a Predator, and added an AFE stage II, and 285/16s on my SRW. We'll see. I've only driven it 10 miles since.

Now. I used to work at a big boat dealer. We had two '03 Dmax crew dually 4x4.
10 mpgs on average pulling 12,000lb boat.
They pulled a 46 Cigarette on a steel Myco trailer (About 22,000lb) from SE FL to CA. The averaged 9 mpgs. Cruised at 60 with the Air cond on.

This poor truck only ever saw two engine oil changes in 50,000 miles, and never a trans fluid change. Never missed a beat.

That truck is what convinced me to buy my D max/allison

Oh, anyone that claims 20+ MPGs is on Cocaine.:rolleyes:

Took a trip to Ga. a few months back fron cent. Fl.
73 mph up 19.5 hand calculated. Trip back at 73 mph 20.5 hand calculated.
Pass the Bump.

Wow, I wish I got that mileage. I only get 12 miles a gallon, unloaded. Been putting on miles to see if it would improve but still at 12 miles a gallon. I have a 04 crew, whats wrong with mine? any suggestions?

Are you going by the dash "computer"???
Gotta do it by hand bro....

all calculations I've done is by hand and i keep log of mileage to gallons purchased, still 12 miles a gal. any ideas?

Mountains, hills, flat driving, wot, all kinds of things affect it. I have only seen 17 and change once highway throught the hills of va and wv, Never even been close to 20

Also, Check your air filters and tire pressure and alignment to increase a little mpg.

Well, i don't know if i've had mine long enough to know, but mine has 550 miles on it, 05 3500 dually, crew cab, LS, 4x4, 6 spd., I have checked mine and am getting between 16 & 17. This is 95% city/rural driving with about 50 miles of interstate or less. I've had my truck a little over a month. Towing with it for the first time today, my camper (5000 lbs.) I don't know about towing mpg yet, today's tow will only be about 30 miles 1 way, in town and rural driving. Let me say one more thing, I LOVE THIS TRUCK!!!!!!!!!!!!!!!!!!!!!

Bad Fuel will also get you BAD MILEAGE

With 6500 miles my last trip at 72-74 mph I got 16.3. Hope to get a little better later.

13.6 in town.

I am somewhat heavy footed however.

18.2 mpg average speed 40 mph,so city and hwy-computer calculated-no towing,no load-

Just pulled a 35' fifth wheel 1600 miles, 10-11 mpg. 65-70 mph
I was getting 16 mpg hwy on 400 mile trip, unloaded on DIC, two months ago i found
out I had a stuck rear caliper ( long story ). Last two trips 20.2 at 69 mph and 21.3 at
60-65 mph on DIC.
