In my automatic Neon I do alot of coasting with the engine on, on the highway. At 100km/h it coasts in neutral at about 1.7L/100km where if I'm in gear just giving enough gas to counteract engine braking the scangauge reads about 3.5 or 4L/100km. In town I don't bother going into neutral unless I can sneak a glide in. My car doesn't read any different idling in or out of gear.
Going back into gear at 50mph is a bit of a trick, I find if I try to rev match by holding the throttle open the tranny will think about going into second gear for a second, but if I just blip the gas it goes into 3rd(highest gear) and I tickle the gas some more and it locks the converter for the next pulse, shoot up to 100km/h and repeat.
On my last trip home I got 5.4L/100km in an auto Neon so I must've done something right!
