if you really want to save gas, just leave it in D and go easy with the pedal.

Manual car uses a little less gas is not because of when to shift, it is because of the tranny itself, manual tranny have different dynamic than auto when it comes to how to transfer power from the engine to the wheels, manual is just more efficient.

if you want to learn when to shift, that will be a different topic
