In city driving, probably a lot. It's less clear cut for my commute, but there are about 3km (out of 45) during my commute where I don't need the engine. With the engine idling, I burn about 2.5L/100km on those parts. With engine off, 0. Averaged over the whole trip, that's about a 0.17L/100km saving. Averaged over a year of driving, around 18L of gas saved.
EDIT: That 18L/year is assuming I only do my commute (rural highways). Once I throw in the city driving, the savings become much more.
