Every 5.3L GM owner that I know that drives in real world driving gets about 2-3 mpg better than my Hemi.

I got 21MPG driving from LA to Phoenix...but 17 on the way back. Must of been downhill on the way there. lol
I got 18-19 city/highway with my 2007 with a 5.3L and I know a few that own Titans that get 13-15 all the time. 2-3 MPG more when you are in the teens is a huge advantage.
