This probably belongs in Driver's Ed.

You should generally avoid using engine braking and coast down instead. Even though you use zero fuel when engine braking in a fuel injected vehicle, you stop much sooner than if you put it in neutral and coast down, so overall it's less efficient. I only engine brake if for instance a light unexpectedly turns red in front of me, or if traffic suddenly slows down.
