You can't quantify how much mpg difference it will make over a tank of fuel because you don't know how much time any given person spends sitting at idle. But, you can reliably state that everyone gets "zero MPG" while their car is at rest idling.

Without the quantity (how much time is spent idling?) we can't quantify.

To quantify with any degree of accuracy would be a hassle, too. One would either need to carry a passenger with a stopwatch and a notepad and do several lengthy experiments or take video of same and spend hours reviewing it.

Those of us who have spent time with a ScanGauge honing our driving technique for best MPG already know the answer.
