What are the hazards of revving the engine in neutral?
2 Answers
Revving the engine in neutral does not cause significant damage, but it mainly wastes fuel. Typically, each instance of revving in neutral consumes approximately 6 milliliters of fuel. Below is relevant information about revving the engine in neutral: 1. Short-term traffic congestion: During brief traffic jams, it is recommended for manual transmission vehicles to shift into neutral and engage the handbrake; for automatic transmission vehicles, shift into N (neutral) and engage the handbrake. This allows the driver to relax and free up both hands and feet. 2. Other hazards: Prolonged pressing of the clutch and brake pedals can increase leg fatigue. Once numbness sets in, it may lead to stalling or even sudden rear-end collisions with the vehicle ahead.
As someone who has been driving for over a decade, I've learned the hard lesson of revving the engine in neutral, and I think it's pretty foolish. Not only does it waste fuel, but the engine revs like crazy, and the increased temperature accelerates cylinder wear, shortening the engine's lifespan in the long run—leading to hefty repair bills. Especially in the summer heat, high RPMs can burn off the oil, causing poor lubrication that damages undercarriage components. What's most annoying is the air pollution it causes, exceeding emission standards and harming the environment; in places with strict environmental regulations, you might even get fined. If it becomes a habit, accidentally shifting into gear while driving can cause the car to lurch forward, damaging the transmission and posing serious safety risks. Wouldn't it be better to save on fuel costs? I suggest being mindful and avoiding revving in neutral—it's responsible for both your car and your wallet.
