I've said it before, I'll say it again.

You have a truck. It has a 300hp engine and weighs 3 tons.  Enjoy it. 

My 2006 gets about the same mileage as my 85hp 1987 Nissan Hardbody and my 190hp 1995 GMC Jimmy.

If you want mileage, then get one of these.  You won't be comfortable but you'll get better mileage:

Larry: 16.9 is pretty good. A Hypertec controller might add a 0.5 mpg at best, and keep your tires inflated.

Clean the Mass Air Flow sensor, install an Cold Air Intake, Tune Up, Performance Exhaust, Performance Tune & Tire Pressure (like avalonandl  suggested), and drive it like an old lady. Keep RPM's at 2000 with all that you might get close to 20 MPG's on the highway.

Also use cruise control anytime you can. I set mine anytime I am doing over 25MPH. My best mileage is 26, my worst is 9. Right now living in the mountains I am getting 16. But I have to get up to speed extremely fast. My neighbor hoods minimum speed limit is 35. And the only access road is off of highway 41. So you have to just jump on the accelerate and climb up hill on the highway to go to Oakhurst or to Fresno. The other problem I have is people do not drive the speed limit. They like to brake before every corner and anytime someone is coming in the other lane. So I spend a lot of time driving with one foot on the gas and one on the brake.
However when I lived in Idaho the ground was flat and the roads open. I averaged 18-20 there. When I would drive from Pocatello to Salt lake City for GTG's I would get 20 -22 all the time, and that was doing 80MPH. So terrain and driving habits and keeping your engine tuned make all the difference in the world.

16 point something is my normal for everyday city/highway driving. When the colder weather arrives and I begin to not use the air conditioning as much, I'll proably see an incremental bump in mileage.

You figure you drive what you want.   :4:

Shane - when'd you move to Coarsegold? I thought you were still in ID.  We were in Bass Lake last spring. Beautiful area!

I got here at the end of May. My father was dying of Cancer. I moved out here in August after he passed to help take care of my mom. I have not been to Bass lake, but I have been to Shaver and a bunch of other places in the mountains. I do love it up here, it is so nice.

Put a block under the gas pedal so you can only go 10% throttle.  :o

It's all the little things you should do that will help your incremental gas mileage but don't expect any significant gains; probably not more than another mpg. SLOW off the start, anticipate red lights & coast when in traffic, drive 55 mph on the highway, keep your tires aired up to maximum sidewall pressure. That's a start.

Clean air filter, clean throttle body, right air pressure, and driving very conservatively, it helped my mileage

I get my best mileage when I drive very conservative. Also keeping the engine tuned and the oil changed. My best mileage comes after doing a complete tuneup, oil change and throttle body. Along with proper tire pressure.

New to the forum, 05 AV Z71 with body cladding, 6" rough country susp. lift.  I live in Honduras and just got my Avalanche about 2 months ago and cannot get over 12.2 mpg average unless I drive it like a granny.  It is nice to drive though if someone does come up with a mpg improvement please post it.
