Are you comparing apples to apples ?

The people that you mentioned may have had the same engine & transmission as you
Did they also have the same rear differential ratio & the same highway tread or all terrain tread ? Did they have the stock intake & exhaust or some after market setup

Everything makes a difference

You can try doing a cooling fan conversion.

Maybe a CAI conversion.

Buy 4 hamsters and put one on the inside of each wheel, and feed them apples.

I have the same model 04 hemi quad cab and so far the best I have been getting is 12.1 avg and I only have an exhaust and drop in k&n air filter. I checked the psi on my tires too and they were all low that could help very little. My next step is to get a tune up and change the fuel injectors that might help a bit too.

Face it people, these big, heavy trucks are not goiny to get Civic fuel milage. Tuners, programmers, CAI, exhaust, and other tricks will not work, I repeat, will not work. Keep you truck tuned up, clean air filter, proper tire pressure, not carrying extra weight, and proper driving techniques are going to get the best milage. If you need more MPG after that, I suggest you trade for something smaller.

If I am gonna trade it for something else it wont be smaller it will be bigger like a 2500 Cummins diesel. Those suckers get good gas mileage from what I hear and saw and they can haul a$$. If you want to stay with Dodge trucks you could always go this route.

Cummins dont get as good of mileage as everyone thinks and the cost of maintenance will put you deeper in the hole then a Hemi
They average about 16 on more expensive fuel and they new ones are worse
12 mpg at $3.29 a gallon here or 16 at $3.99
They do move though

I had a 2007 Dodge diesel and it only did 2 mpg better while pulling my boat and not as good as my 2010 Hemi when not towing. Result less money for fuel and a lot less for maintenance.

You're not gonna get very good mileage out of a full sized truck. There is no way around it. I think the newer trucks will get slightly better that what you're experiencing, but not much.

If you need better mileage, then you need to find a car that is not only smaller, but lighter and is sure to get the better milage.

I recently purchased a Honda Cr-Z. It's a 2 seat hybrid (of sorts) that goes like hell, and still gets 35+ MPG. I use it to run errands around town and just play...

My truck is my family hauler, and going back and forth to work rig

good luck

The window sticker on my Ram claims 13cty 18hwy and it's pretty accurate.


I also own an 08 Malibu LTZ with a 4 banger mated to a 6 speed tranny, on the hwy at 70 mph it will get 39-42 mpg but we mostly drive it in the city and it averages 25 mpg....If a small car designed to get good fuel mileage can only average 25 mpg's there is no way a big heavy brick will get good mpg's.
