Giving gas before releasing the clutch can damage the car. Here is a detailed explanation of stepping on the throttle before releasing the clutch: 1. Poor car condition: If the car is too old, it may lack power, and since it's already old, there's less concern about rough handling. In such cases, for better acceleration, a violent start—giving gas before releasing the clutch—can be chosen. 2. In a hurry: Manual transmission cars have a characteristic of being prone to stalling. Especially when in a rush, often the left foot releases too quickly, leading to stalling. Therefore, in such situations, one can choose to step on the throttle first to raise the RPM, then release the clutch. This not only ensures a quick start but also reduces the likelihood of stalling. Additionally, during this operation, the RPM drops slowly, making it easier to shift gears. 3. Starting on a long, steep slope: Mountain roads are not only steep but also narrow, especially in small villages. On such roads, it's common to stop the car to wait for the other vehicle to pass before proceeding.

After driving manual for a long time, I've figured out some tricks. The habit of revving the engine before releasing the clutch really wears out the clutch plates. Back when I was learning to drive, I often rushed by stepping on the gas to two or three thousand RPM and then suddenly letting go of the clutch. The car would lurch forward, but the burnt smell coming from underneath was undeniable. The principle is simple: at high RPMs, the clutch plates engage harshly, generating heat from metal friction that directly burns the surface. Over time, this wears them thin. Doing this repeatedly in traffic doubles the wear. Now, I've switched to giving gas while partially engaging the clutch: lift the left foot until the car slightly vibrates, then gently tap the gas with the right foot to add power, before fully releasing the clutch. It's smoother, protects the drivetrain, and actually makes for quicker starts at traffic lights.

My old manual transmission car has been driven over 100,000 kilometers by me, and the clutch has never been replaced. The key is to avoid stomping on the gas pedal while abruptly releasing the clutch. Once, a mechanic pointed at my friend's car and said the clutch disc was worn as thin as paper because he always revved the engine to 3,000 RPM before releasing the clutch. High-temperature friction can cause the pressure plate springs to anneal, and metal fatigue can make it difficult to shift gears. The correct method is to feel the semi-engagement point: when lifting the clutch until the car slightly trembles, simultaneously apply a bit of throttle. It's like holding a bowl of water—coordinate your hands, eyes, and feet. Adding some throttle to prevent rolling back when starting on a slope is understandable, but on flat roads, there's really no need for aggressive maneuvers.

Bad for the car, this habit needs to change. Engaging the clutch at high RPM is like rubbing sandpaper on brake discs—the friction heat directly burns the metal layer. Last year when I helped my nephew fix his car, we found the clutch plates worn through after disassembly, all because he kept revving to 4,000 RPM for starts. Short-term it feels powerful, but long-term the money saved on fuel won’t cover replacing the clutch trio. Gentle operation isn’t hard: lift the clutch while lightly applying throttle, keeping RPM around 1,500 is ideal.

Over the years of teaching people to drive, this is the most common mistake I correct. Beginners often mistakenly believe that revving the engine can prevent stalling, but it actually accelerates wear. Last month, a student's car had its clutch plate replaced, and upon removal, the surface was covered in heat cracks. Proper coordination between the clutch and accelerator is like dancing: lift the clutch to the semi-engaged point, gently press the accelerator with the right foot when the car shakes, and continue lifting the clutch once you feel the power engage. Throughout this process, the accelerator depth should not exceed one-quarter, and the RPM should be kept below 1,800. In traffic jams, use the semi-engaged state more often to reduce the number of complete separations.

Last week, while helping a friend troubleshoot a manual transmission, the clutch noise turned out to be a chronic issue caused by prolonged revving before engagement. Especially in winter when the car is cold, the high viscosity of the engine oil makes the clutch engagement harsh, leading to more severe wear. In special scenarios like icy or snowy slopes, a slight throttle input is indeed necessary to prevent rolling back, but remember the three-second rule: don't rev for more than three seconds, keep the RPM under 2000, and immediately transition to the half-clutch state. For starting on flat roads, it's completely unnecessary—just lift your left foot to the vibration point and lightly tap the throttle with your right foot, which saves the clutch and ensures smooth operation.
