Coasting, Engine Braking, Pulse and Glide

Read a very interesting post at about engine braking vs coasting in neutral.

Apparently when coasting in gear or engine braking (on a standard), the engine cuts off fuel altogether while decelerating until it hits a predetermined limit. When coasting in neutral the engine still uses fuel but at a low rate(idle).

I'll have to experiment with this and compare a downhill glide in neutral vs. say 5th gear.

Coasting in Gear worst best best
Coasting in Neutral good worst good
Coasting Engine Off best best worst
