I picked up a 2012 Z71 Extended cab, 5.3 with 3:42 gears a few weeks ago. I have been avging about 16.5 with a high of 18.3. We previously had a 06 with the 4.8 and it drank fuel. It just wasn't enough motor for the hills around here. Pretty happy with the mpg I am getting. I didn't buy it for the fuel economy lol.
