Stop / Starting Engine Fuel Consumption Query

[NeilVR6 0]

From what I have read in car magazines.

Starting modern engines I understand it provides accurate amount of fuel to the engine.

Old car engines dump quite a lot of fuel initially to start the engine.

Where does the VR6 12v stand?

Being more CO2 conscious and with the increase of queues and road traffic. Shutting off the engine for small periods of time and starting it again, am I wasting fuel?

from what I understand that was the whole point of having a fuel injected engine, to make sure that you always had the correct amount of fuel put into the cylinders, as it is measured by a fair few different computer controlled instruments, where as a carbed engine doesn't have any of these comodities so it wouldn't be as fuel effiecient. But then again a petrol 2.8v6 is never going to be enviromentally friendly.
