Does Coasting in Neutral Save or Waste Fuel?

[DakotaDella]

Not necessarily fuel-saving, and may even waste fuel. Many modern vehicles are equipped with electronically controlled fuel injection systems. When the car is shifted into neutral, the ECU defaults to assuming the car is idling, thereby increasing fuel injection to maintain idle speed. The electronic fuel injection control system inherently has fuel reduction or cutoff functions. Shifting to neutral in such scenarios not only disables these functions but also increases fuel injection. Fuel-saving tips: 1. Smooth Driving: One of the most practical and effective fuel-saving methods is maintaining steady driving. For small-displacement vehicles, it's best to keep speeds between 60 to 80 km/h, while for larger-displacement vehicles, maintain speeds between 80 to 100 km/h. 2. Avoid Congested Routes: Before driving, check the route. If it's congested, it's best to detour. In traffic jams, the car not only can't move but also remains in an operating state, which wastes fuel. 3. Reduce Vehicle Weight: The weight of the car also increases fuel consumption. Therefore, if some items in the car are temporarily not needed, try to remove them to reduce the vehicle's weight.
