Is it more fuel-efficient to keep the accelerator pedal pressed or to press and release it alternately while driving?

[LeParker]

When driving, it is better to press and release the accelerator pedal alternately rather than keeping it deeply pressed continuously, as this significantly increases fuel consumption. The correct method for pressing the accelerator pedal is: adjust the movement of your foot on the pedal. Place the heel of your right foot on the floor of the driver's compartment as a pivot point, and press the pedal with the ball of your foot, using the ankle joint's flexion and extension to press and release the pedal. Key considerations for pressing the accelerator pedal include: 1. Press and release the pedal gently and smoothly; 2. Coordinate the release of the clutch with pressing the accelerator promptly and precisely; 3. Select the appropriate gear to ensure the engine operates mostly at medium RPM and with a wider throttle opening for fuel efficiency; 4. Before stopping or turning off the engine, release the accelerator pedal first and avoid revving the engine abruptly.
