Fuel economy when coasting
A leaflet from the Department of Transport ("Be a smarter driver and save money") says this: "Don't coast downhill or towards the lights in neutral as this uses more fuel." Is this true?

Yes. The engine requires a little bit of fuel to tick over while coasting out of gear. In gear with foot off the accelerator, the drivetrain turns the engine and the fuel supply to it is cut off entirely.

Real MPG enables you to register the fuel economy you are actually getting against your make and model of car, its engine and type of transmission.
Every time you enter an average consumption figure against your car, the overall average automatically adjusts to reflect it.
