Suggest to anyone new that you start doing this, even coming up to stops you can coast quite far in neutral.
While coasting engine idling my cars are consuming gasoline : 1l/h (0.26g/h).

Usually I'm using DFCO (Decelerating Fuel Cut Off) aka Engine Brake. I'm using Coasting Engine Idling if I know I need more speed at the bottom of the current hill to go up the next hill.
I never use EOC (Engine Off Coasting) as I feel this is too dangerous for me.

Tips #43 is talking about the different ways to "brake". For each one there is at least one situation where it's best.
Anybody have to thing about his feeling for each technique 1st and apply 2nd.
In any way, a technique you don't feel good with, will never be a good technique for you to apply.

Remember the (2nd) credo of this forum : safety 1st, courtesy 2nd and saving gas 3rd.

Life long, safe and prosper ;-)
