[growly]

So what are you getting?
What mods have you made?
With a steel deck and 2 sleds(Phazer and 550 poo both fans) 4.10 gears,auto.,k&n,265/75/16 tires, Stock other than the k&n, I'm getting about 11 miles to the gallon hwy. Need to get it up a little more.

 

[johndeereman346]

Im assuming you have a gas job and 11 mpg is not good i get 18 empty and 12 with 7000lb trailer, chip intake and exhaust

 

[Rucky]

2004 2500 HD with the 6.0 got 13 last time we checked. K&N intake. We were also pulling two sleds on a triton two place WITH salt guards. They likely make a huge difference as we found out when we used to pull with an S10

 

[johndeereman346]

Forgot to tell ya that im looking at getting headers too just for a little bit more juice and flow, but look into getting your cat deleted if you know any compan that tunes vehicle computers.....light speed innovations in red deer....then you can have ultimate power and milage.

 

[medler]

My truck empty with 4.10 gears i get 16-17 mpg .Through the mountains with Holiday trailer about 11-12

 

[growly]

yup Chev 6L gasser, It's a 2500 non HD so it has the auto T-case which will make a difference. It's also a 2000 with 140,000 k's

 

[slednek]

16 empty and 10 -11 pulling 6500lb travel trailer. 12-13 with a 2 place and 1 in the box.

 

[new24stroke]

I get 16 MPG empty with mine.

I had the exact same set up with almost 200,000K and was pulling waaaay better numbers . 16-18! One thing I noticed years ago though was pulling the trailer at a buck twenty you could literally see the gas gauge moving. Slowing down to 100 or 110 nearly doubled the mileage.

Course now I drive an 07 350 Harley and no comparison (diesels the only way!!)

 

[foothills m8]

I get 12+ with a m1000 and m8 on steel deck.It all depends on how ya driver er. usally above speed limit.Just about 300 kms on er.5 speed helps.

 

[sledneck48]

Mines got no upgrades and id be lucky to get 10 in the city and 12 on the highway.

 

[bigz64]

a loaded 6.0 liter thats not bad. i had a 01 6.0 liter 500km per 98 liter (12mpg) tank now a 08 6.0 liter 850km per 140 liter tank (14 mpg). work trucks

 

[Cowboyup083]

2007 2500 HD 6.0l stock with 4:10 rear end, I get 14-16 mpg empty. Has soon has a hook up to anything 12 mpg, camper, boat, or seld trailer

 

[duch17]

Ive got a 06 1500HD with the 6L and get around 18-20 on the highway sometimes a little more or a lot less, but as soon as anything is hooked on to the ball your luck to get 13 and sometimes if there is a little wind your down to 10. It has little bigger tires and a KN cold air kit.

 

[maierch]

I have an 08 Vortec Max. I checked the fuel milage after I put a K & N on and was getting 17 MPG on the highway with permium fuel. I also find I get about a 1 MPG boost from running premium which at the 10 cent price difference is 2 cents away from being worth it but you do get a bit further down the road without stopping!

 

[rondun]

:d We install propane on the 6l GMC the mileage does not inprove but it costs less to drive. On my 05 GMC I get 19 on propane @57.9 l. I drove 3400km last summer pulling my 22ft trailer for $513.00 We went all over B.C. and Alberta. My propane system is a Prins.

 

[03rmk8]

im running a 05 6l 1500hd cold air dual exaust bully dog porgramer im getting around 14 to 15 mpg on 265/75 r16. but i like that i can pull all my toys and my buddies in one trip to the camp.

 

[rondun]

Try Propane our cost now is .499l gas here is .999l (in Fort St. John) I have more get up and go than gas @ half the price. You can get it done almost anywhere. You can e-mail me I can help you out we do have some used systems (ron_dun@hotmail.com)

 

[duch17]

I just drove out to Victoria yesterday and from Calgary to Victoria I got 21.2 MPG, that is the best I have ever gotten. I just put a box cover on before we left from calgary and have a kn cold air kit

 

[rondun]

Was the cold air kit noisy when on the throttle climing a hill or passing. My buddy with a speed shop wants me to try one, But I worry that it will be too noisy. I pull a 24ft travel trailer.
