Fuel Saving Tips
Contrary to popular myth, coasting will not save fuel. This is particularly true with more modern cars. When you "coast" i.e. with your foot on the clutch or in neutral, the ECU continues to inject fuel at a sufficient rate to allow the engine to idle, usually around 800-1000rpm. However, by just removing your foot from the accelerator the ECU no longer needs to inject fuel as the drivetrain continues to rotate the engine stopping it from stalling. So, just plan ahead and make use of "engine braking" instead of coasting. This will also save wear and tear on your clutch and brakes!
