Can a manual car slide in neutral save fuel?

Sliding in neutral by hand may not save fuel, but you may have to pay for fuel. Because many current models are electronic control systems, when the vehicle is switched to neutral, ECU will increase the fuel injection quantity to maintain the idle speed of the vehicle. The electronic control system has the function of reducing fuel or cutting off fuel. If the owner slides into neutral, this function will be lost and the fuel injection quantity will increase.

Damage to the car caused by manual neutral sliding;

1, frustration

When the vehicle taxies to a certain speed in neutral, if the neutral is cancelled and the corresponding gear is replaced, there will be obvious frustration. At the same time, the sudden output of power may damage the gears of the gearbox.

2. The braking efficiency is reduced.

Once in neutral, the driving force of the driving wheel will be lost, the connection between the engine and the driving wheel will be lost, and the engine can no longer contain the driving wheel. At this time, if an emergency occurs, the braking force of the vehicle will be provided by the brakes, but the braking force provided by the brakes is also limited, so the braking distance becomes longer and the possibility of serious accidents increases.

3. Affect engine life.

When idling, the oil pump is at a low speed and the oil supply is reduced. After a long time, the cooling, cleaning, lubrication and sealing functions of the engine will be greatly reduced. If the owner often slides in neutral, it will aggravate the wear of the engine.

4. The transmission gear is broken.

When the vehicle slides in neutral on the downhill section, the sliding speed of the vehicle is higher and the gear of the transmission runs faster. When the gear is changed from neutral to other gears again, the impact on the gear will be very great, and the gear will appear metal fatigue, and even break or even completely fall off in severe cases.
