What Are the Hazards of Revving the Engine in Neutral Gear?
2 Answers
Revving the engine in neutral gear doesn't cause significant harm, but it primarily wastes fuel. Typically, each instance of revving the engine in neutral consumes approximately 6 milliliters of fuel. Below is relevant information about revving the engine in neutral gear: Short-term traffic congestion: During short-term 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 their hands and feet. Other hazards: If the clutch and brake pedals are pressed for extended periods, it can increase the burden on the legs. Once numbness sets in, it may lead to stalling or even sudden rear-end collisions with the vehicle ahead.
I've been driving manual transmission cars for over a decade. Although revving the engine in neutral might sound cool, it's actually terrible for your car, especially at high RPMs when the engine vibrates violently. This increases friction in critical components like piston rings and connecting rods, leading to premature wear. I used to do this a few times myself, and later found carbon buildup on the spark plugs when I took the car to the shop. It's also a huge waste of gasoline - burning fuel while the car isn't even moving, which increases emissions and pollutes the environment. For winter warm-up, just a few seconds of idling is sufficient. Doing this long-term can cause oil pressure system issues or accelerate catalytic converter aging. In short, try to avoid this habit. It's much better for your car to just shift into gear and drive after starting.
