You will always get better avg mpg coasting in N vs D or S... this is due to RPM. Coasting in N is like putting the clutch in on a manual trans. As soon as you put it into N your RPM drops to idle, where as if you leave it in D or S your RPM is matched per gear and vehicle speed programming. as you slow down the auto will downshift raising the RPM... the higher the RPM the lower the MPG and vice versa.
