Krash,


It all depends on how you drive, the wieght, tire size, what kind of driving you do and so on. I would say during the winter(worse mileage) anywhere from 14-20mpg. Any other time of year should be about 1-2mpg better than winter.

I get 18.5 unloaded in the city.

 

[Victory Red]

summertime unloaded city/hwy mix I get 19.5, winter time blended upper 16's to mid 17's depending on cold.

Krash610,


Mileage is speed dependant. 60 to 65 mpg usually yielded 20mpg+. Around 70mph that went to 19mpg. 75mph was 18mpg and 80+mph was barely in the 17's.

thanks for the replies


this is better than i thought.

I average an honest 20mpg with my Dmax. Depending on my driving I've seen 18-22mpg per tank when empty. Hey captainmal, how about an honest opinion/comparison of that new Dodge you're driving. Edited by: GMCTRUCK

KRASH610 running solo, the first tank I got 17.3 (17.1 DIC), second tank I got 16.1 (16.4 DIC) same pump, 50/50 city highway, running Primrose 409 and a fair amount of idling. Oh, and on the second tank I lost about a gallon doing my post OEM filter install. Much better than my '02 8.1L.

My 04 had about 800 miles on it when I went home from college last weekend. I got 20.5 mpg, and it would be really neat if that came up as it got broke in. That was all highway averaging about 60-62 mph.

17 - 18 in the city... 8 - 10 towing something substantial.

On a trip from Cleveland, Ohio to Gainesville, Florida, I got a high of 22.77 MPG. This was fuel stop to highway, to fuel stop. No idleing or city driving in between, 65 to 75 MPH. Most tanks were around 19.8 MPG driving 75-80+ MPH!!. I got 18 MPG on a 400 mile tank tooling around the Gainesville area.

GMC Truck,


There is a recent opinion on this site and more on the Dodge/Cummins forum of this site. Also check dieselram.com.


Want the short version?????

In my Silverado K3500 carrying 1000 pounds my typical load,


I get 15 mpg city and highway @ 70. I get 13 running 90 mph on western highways.


My best is 16.9, driving about 60-65.


Stock tires and wheels.


It seems the dually tires hurt the mileage. I think lighter wheels would help. I'd be interested in seeing what other duramax dually drivers are getting with various tire and wheel combinations.

Completely stock 2002 3500 CCLB truck except for fuel filter and aire filter.





I average 15.5 - 16 MPG per tank. If I drive more highway and stay near the speed limit I have gotten 17+. If I run as fast as I want I get 15. Towing it drops to around 13.

 

[GMC2500HD]

I did a run to San Antonio from Houston, down there I was getting 18.9 with mild wind blowing and on the way back was getting 20.2 with about the same wind. Also had the cruise set at 75 mph both ways and coming back we were loaded with x-mas junk.haha

2001 Crew cab towing 10000lbs= 13.3 mpg (still) 16.6 empty


20000lbs= 8 mpg


2003 Reg Cab towing 10000lbs=14 mpg 17 empty


20000lbs= 10 mpg

I don't know if a few of us have gotten magic trucks or what, or if the stars were aligned, because I've gotten a best of 25MPG. On seperate occasions I have gotten 24.3 and 23.7MPG.. with stock tires and just a K&N filter, straight piped exhaust. This is running under 2k RPM's on the freeway (speed limits on that trip were 90 - 100 km/h).


Average I get about 19, half highway half town, I live in a rural area, have a light truck (reg. cab) and a handshaker so I guess that helps it be a bit more efficient too.. Even with big tires on, calculating for tire size I can get 22 when I try.

11 in tow and 14 round town

 

[Jon S]

I've had my '04 for only a month. Bone stock. 2,850 miles, 70% highway, 30% city, no towing. No additives, blended winter fuel. Best tank = 21.4, Worst tank = 19.0, Lifetime average mpg = 19.95.

 

[Idle_Chatter]

I've gotten an over-all average of 18.2 mpg in the 28 months that I've been driving my truck. I typically get 18-20 mpg empty in the warm months and 14-16 towing my 6x12x6 enclosed trailer. I've been getting 15-16 mpg empty the last couple of months on "winterized fuel"
