In my opinion, EOC is hard on the starter and ignotion switch and bump starting is hard on motor mounts and axles. When my car is coasting, the engine is on so I have total control and an idling Metro gets like 90MPG by estimation.
I am already averaging 57-60MPG without EOC and if I was to use this practice to save more fuel, I feel that having to replace worn components would cost more in the long run.
Remember! I am not a "Hypermiler". I am an "EcoModder".
