DFCO and auto tranny's just don't work, don't worry about the fuel useage will idling and coasting, anytime with the cobalt and I'm coasting over 30 mph I'm 99+ mpg. since I have a manual I can DFCO on down hills if I down shift and keep my RPM over 2k, so I get engine breaking, really I should have started my coast sooner if I need the engine to slow me down.

Focus on not needing to use the brakes that's where the best gains are.
