The technique :

Desired speed and leave the car in neutral.

By leaving the car in gear slows and you have to accelerate to maintain speed .

Leaving the car in neutral slows 3 or 4 times slower .

City at a speed of 40 km / h (24 mp/h) works great.

By road also works well if not exceeded 100km / h (62 mp/h)

On the road with a slight drop and the longest in gear loses speed.

On the road with a slight drop in neutral is gaining speed.

Do not turn off the engine to use less fuel if you leave it in neutral. The power steering and brake assist is lost.

Pros :

The car loses less speed when not accelerating.
These less time accelerating.
Less consumption. I'm not sure .

Cons :

It is not recommended to use it if there is traffic .
Speeding downhill can be dangerous.
