[5.0 Junkie]

I have a Cruze Eco with Manual trans. They are lighter than the other cars also. I am slightly over 40mpg lifetime. I am a Hunter Engineering HD sales rep and cover 5 states in the midwest. Best tank was when the car was 5 days old. Drove from Louisville to KC and got 44.2mpg driving the speed limit with cruise set. Some of the lower lifetime mpg is due to making frequent short trips in town.

If you drive 65 with the cruise, you will get 44-46mpg pretty easy. Drive 55 and you will get up to 50mpg.

So far, I'm just running about 38psi in tires with no other mods. Going up to 40psi to see if it helps any. There isn't really any "low hanging fruit" on these cars as far as aero mods go. GM pretty much did them all. I may lower it another .5" to see if that helps any and check for a rear under tray.
