What are the effects of revving the engine in neutral?
3 Answers
Revving the engine in neutral can cause damage to the car. In neutral, the engine has no load, and suddenly pressing the accelerator can subject some internal components to significant inertial forces, which may shorten the engine's lifespan. Precautions for using a car engine are as follows: 1. Avoid driving in neutral: The engine itself has a deceleration fuel-cut function, and driving in neutral is not conducive to fuel economy. 2. Pay attention to observation while using the vehicle. If oil is found on the ground, determine whether there is an engine oil leak and promptly communicate with the car 4S shop to eliminate potential safety hazards. 3. For cars equipped with turbochargers, do not turn off the engine immediately after high-speed driving or climbing a slope. Let it idle for 10 minutes before shutting it off. Turbocharged cars accumulate carbon deposits several times faster than naturally aspirated cars. 4. When brake fluid is contaminated with or absorbs water, or if impurities or sediments are found in the brake fluid, it should be replaced or carefully filtered. Otherwise, it may result in insufficient braking pressure, affecting braking performance.
I've seen plenty of drivers revving the engine hard in neutral over the years, and it feels like such a waste. Fuel gushes out, the tachometer shoots up, but the car just sits there—essentially throwing gasoline money away. The engine components work too aggressively at high RPMs without any load to support them, which can easily damage piston rings or bearings, significantly shortening their lifespan. The risk of overheating also increases dramatically, as the cooling system struggles to handle the heat, leading to more carbon buildup. This can make ignition more difficult later on, and you might even end up spewing black smoke at pedestrians. Not to mention the noise—doing this long-term will surely make your repair bills sting and even compromise driving safety. Developing such a habit is terrible; it's better to lightly tap the throttle only when needed, saving money and maintaining the car. Next time you're at a red light or parked, keep it quiet to avoid your car protesting.
Hey buddy, my friend tried revving the engine in neutral for fun the other day, and it turned out pretty awkward. The fuel consumption skyrocketed, and the gas tank seemed to be leaking—half a tank wasted just like that. The engine revved like crazy, buzzing nonstop, but the car didn't move an inch, purely burning fuel for nothing. What's worse, the mechanical wear doubled, and internal engine parts might age prematurely, leading to expensive replacements. The rising temperature could easily trigger the protection system, and if the engine blows, it's game over. Carbon buildup is inevitable, leaving the engine dirty and making it rattle during startup. Just take it easy—keep the RPM steady when driving normally, avoid unnecessary revving, and you'll stay safe, eco-friendly, and extend your car's lifespan. Remember this lesson to protect your ride for more years to come.
