I get about 17-18 with mostly city driving. On the highway, if I keep it at 65-70, I saw about 24.5. I have 3.73 gears and man. trans. I have 5,100 miles now. I also have issues with my "oil life indicator," which told me I was at 10% oil life with just 4,700 miles. Apparently there is a TSB for this problem...and they will reprogram the PCM. Maybe...this will update the Avg. MPG too? I mean, if my 2007 with 3.55s at 70 mph could pull 30mpg, and my 2011 with 3.73s at 70 pulls the same RPM (2,200)...why can't I pull similar mpg numbers?
