I get 16-17 running around here. I havn't taken it on a long trip yet but have run 300 miles roundtrip. I got right at 20 on that one. The truck only has 8500 miles on it. When I had the Duramax, I averaged over 21 mpg on a 4500 mile trip. I would hope this one will get at least that much. I'm very happy with the milage and the truck overall.

I have an 09 with the 5.3 fuel management and 3.73's. I am getting 16.7 and that's with letting the truck warm up. That is according to the gauge in the information center.

And not just hype because you want to think your truck is ever going to get mileage like a Prius.

If you didn't get AFM big deal consider yourself better off from potential long term problems. Now if you didn't get the 6 speed transmission, Bummer

Eddie, Give us some feed back on your mpg

17 at best. I'm not impressed.

I just filled up for the first time so I will let you know what I get once its done. Right now I only drive in the city, so it wont be any highway mileage. I am stationed in Hawaii, and literaly drive like 2 miles to work on post. I was really hoping to get 20+ on the highway, so we will see. If I get 14 in the city I will be very pleased, as my reg cab dodge 4x4 only got 10. Give me another week and i will let you know what kind of mileage I got out of pure "city" driving.
