I get about 13.5 in my AWD and i'm always in the pedal... Live in a town with lots of mountains and big hills and such too...

 

After a month of ownership and logging my fuel purchases in my fuel data book, I can say with accuracy that I am getting:

11.4 MPG city / 19.6 MPG Highway.

But it's still new and I like to hear the Hemi sing. Hopefully my foot gets lighter.

 

I did not think the 03's 5.7's had an EGR valve.???

 

Well I know the 04s and 05s had them and thats the same exact engine just with better valve springs so I would think it does. To be honest idk if my 08 has one but then I haven't really looked for it lol

 

I get about 10.5 city, 14 highway. I try driving easy but that's no fun

 

I know right?!

 

I get 13 /- on the highway or in the city. ( notice how there is no + ) It's a truck, 13 is Great LOL!!

 

Uhh no it's not... I get 17-18 on the highway easily. 15 is the worst I've ever gotten on the highway. My city is 9-11 though which is the worst I've gotten and the best I've gotten

 

Mileage will vary from truck to truck and driver to driver.

No one has the same truck or the same driving habits

Tuners, CAIs, O2's, stats, lifts/drops, tires, air pressure, winds, hills, ethanol, spark plugs and SO MUCH more all make up mileage.

 

Well my numbers when stock were higher than what I have now (which are what I posted). And that was when I was 17 and all excited that I had a HEMI so I'll let that speak for my driving habits
