Sometimes I coast in neutral with the engine on but I worry about shifting back into gear, I mean by truck is old and I don't want to overstress anything. But it makes a HUGE difference in how far I coast, my transmission must really transmit the engine braking effect well (unlike some which will almost fully disengage when not on throttle).
I've only EOC in my GFs car, because her auto shifter is on the floor and much easier to select neutral in (unlike the shifter on the column in my truck where I sometimes go flying past neutral and into R

). And then I only do it when I'm rolling up to a red light that I know will take at least 1-2 mins to cycle. This way I figure I'll save the little bit heading to the light and sitting at the light (I hate seeing the 0 MPG while at a light and idling). I wish I didn't have to restart though, the car revs so high and it stressed my starter and electrical system. I think the car just needs to idle at 300-400rpm somehow....
