I have never and will never do engine off coasting in any auto equipped car. Autos require hydraulic pressure to function as well as for lubrication. If you want to fry your transmission and spend a bundle of money then go ahead and shut off the engine while you are going 60 MPH. I know I won't.. The Insight went 150 MPG coasting at 16 MPH, os it used 16/150ths of a gallon idling.

Please tell me more! At what speeds did you reengage from N to D?
If you switch to imperial units, you'll find that it's doing greater than 150mpg. Going downhill in gear feathering the throttle, it'll do 235mpg at 55mph. Which is consistent with the average mpg i get. Meaning i still leave 10-20mpg on the table if i were to EOC every down hill at infinite mpg.
