Is it good for the car to press and release the accelerator frequently?

[DeGideon]

Frequently pressing and releasing the accelerator does not cause damage to the car. It is very common to press the accelerator and then immediately release it to step on the brake during traffic jams. The accelerator pedal does not directly control the fuel injection volume of the engine. When the accelerator pedal is pressed, the throttle opening increases, allowing more air to enter the engine. The ECU then commands the fuel injection system to inject more fuel, causing the engine speed to rise and the car to accelerate. Over time, carbon deposits may form on the throttle, which can affect the normal operation of the engine. It is recommended to regularly clean the carbon deposits from the throttle. Cleaning the throttle's carbon deposits simply requires removing the throttle and cleaning it with a specialized cleaning agent.

I've been driving for nearly twenty years and often see novices liking to press and release the throttle repeatedly in traffic jams, thinking it saves fuel or controls speed. But this habit is really bad! Frequent operations can strain the engine, subjecting pistons and bearings to uneven pressure and accelerating wear. Once, a car I had was frequently driven this way and started making strange noises after only 60,000 kilometers, costing thousands to repair. It also increases fuel consumption—every acceleration burns extra fuel, hurting your wallet in the long run. It's best to develop a habit of smooth pedal control, maintaining a steady speed on highways and gently pressing and releasing in city driving. Paying more attention during vehicle maintenance can extend engine life.

I noticed some details about car maintenance and found that frequently pressing and releasing the throttle is indeed not good for the engine and transmission. This kind of operation can cause uneven load on the transmission, leading to excessive gear wear or jerky shifts over time, which affects driving comfort. Fuel consumption also increases because the system has to respond anew each time the throttle is pressed, wasting fuel unnecessarily. I remember when I had my old car, there was a month when I drove like this frequently in the city, and the fuel tank emptied much faster, costing me more money on gas. It's recommended to use cruise control or anticipate traffic rhythms to maintain a more stable throttle, making the car respond more smoothly and saving money.

I've found that frequently pressing and releasing the throttle is really harmful to the car. It increases internal engine wear and shortens the lifespan of components. Especially with modern cars' sensitive electronic systems, repeated operations may cause the control module to overheat or malfunction, making repairs troublesome and expensive. It also increases carbon emissions, which isn't recommended from an environmental perspective. When I drive, I try to accelerate smoothly to protect the engine and save some fuel. Don't forget to regularly check your car's components.

I've seen many cars suffer from this habit. Frequently releasing and pressing the throttle causes fluctuating loads on the transmission and engine components, leading to premature wear or performance degradation. Fuel consumption increases significantly – my own experience shows it can cost dozens of yuan extra per month. Safety-wise, it may also cause misoperation; suddenly releasing the throttle at high speeds could lead to loss of control. I recommend maintaining predictable speed and rhythm during daily driving. Keeping steady pedal control is most crucial for vehicle maintenance.

When I was young, I used to drive like this—always pumping the accelerator at traffic lights, thinking it would save fuel or be fun. As a result, the engine wore out early, and repair costs soared. Later, I realized this accelerates engine wear and increases fuel consumption by over 10%. Smooth driving is better—it extends the vehicle's lifespan and reduces pollution. Now, I’ve developed the habit of gently easing onto the throttle and accelerating smoothly in traffic, protecting my beloved car while enjoying peace of mind. Regular vehicle checks also help prevent major repairs.
