I am an owner of a 2005 4wd 2500 Av!! I am reading in some of these forums that some guys are getting up to 15-18 mpg for their 2500's and when i calculate my mileage right now i am lucky to get 12. Are there any main things i can check and change to start getting the mileage all these other guys are getting? any help is greatly appreciated
 
Keep a good tune and clean the Maf regularly. Take off slow from a stop and if you know you have to stop at a stoplight slow down and let it change then speed back up. Stay below 75 mine gets its best mileage below 65.

If you have e rated tires keep the pressure up.
 
+1 on what MS03 2500 said.
I cleaned the MAF sensor on my '03 about two weeks ago, and inflated the tires to 40 in the front, 38 in the rear.
Seems to ride better, and based on my DIC, I'm getting about 1.5MPG better without changing driving habits.
 
For a 2500 those are highway only numbers, with stock suspension height and tire size.
 
You are right Wazbro do not put big tires or lift it, your gas mileage will suffer.

Well 2500 are 8,000 pounds maybe you should check your roll.
 
I agree on what everyone else said. Be very easy on the gas when getting up to speed. Slow down, don't speed. The faster you drive the lower your MPG will be. Keep tires up to proper pressure, the higher the better for MPG. Anticipate lights, stop signs, etc as much as possible, and try to take your foot off of the gas way before you need to stop instead of waiting till the last minute and then hitting the brakes.

Many of the mods we do to our trucks affect the aerodynamics, GM is very careful when they design to maximize the aerodynamics in order to meet the CAFE MPG numbers. Keep the bed covers on, they are good for at least 1.5 MPG. Bug deflectors hurt your MPG. The front spoiler under the bumper hurts MPG if removed. People have reported that the "leveling" kits (or cranking up the front torsion bars) will hurt the MPG.

When people report their MPGs always ask what their driving conditions are. I have never, with the Av, been able to get a 20 MPG tank, best is 19.9, worst was 13.0 but I have some traffic, lights, etc. Over 100,000 miles the average is 15.2. Owned it since new and logged every fillup. My other car is a 2001 Honda Insight and my worst tank is a 60.8 MPG tank.

I get around 40 MPG in my 99 Saturn. My must-have commuter car.

Sorry. Missed the "Too big for a commuter" indication.
All the more reason to not expect outstanding MPG.

I'm not raggin' on anybody. But, really, it's not like the Av is a hybrid, or sumthin'.

Jrock: There is no way a 2500 gets 18 mpg. It simply won't happen. These trucks are 6600 lbs at least and the 8.1 is not meant to be thrifty. I get 12 mpg everyday driving. I can get 14-15 mpg highway at 60-65mph. I have 106,000 miles o9n mine, I know what they can and can't do.

Follow these simple rules:
1. stick with AC plugs (stay away from bosch and E3), and keep your vehicle in good tune
2. Get a tune or a programmer and install a tune
3. Stock height- no lift, and stock tires- Big tires a no-no- more rolling resistance.
4. drive it easy, coast a lot.
5. ask for suggestions before you go out and spend $ on some mods

Good luck.

Put my 05 2500 Avy on a certified set of CAT scales a couple weeks ago.  At the time, I had about 60 lbs of gas, about 250 lbs of stuff in the back (up by the cab) and no one sitting in it:
Front axle: 3560
Rear axle: 3500

A full tank of gas (~220lbs), 3 other people and a little bit of stuff will get to 8000 lbs fairly easily.

Yeah that's about right... take the 250 lbs out and 60 gals of gas you will be at about 6500 lbs.

Bro you got the wrong vehicle if you are worried about fuel mileage. Use the CC when you can, roll into and out of the throttle, use the 93 octane with no ethanol
