Turtle At what point is it advantageous to shut the engine off while driving?

Hey everyone, I'm Andrew and yeah this is my first post. I'm trying to figure out if and when I should shut my engine off while driving. At a long stop light? I always do. Coasting down a long down hill straight away? I often do. My real question is at what point does it become advantageous to shut the engine off? Someone once told me the engine uses more fuel to start up than you would use just sitting at idle but I don't think that is necessarily true. Any input?
