RPM between 2000 and 2500 is the most fuel-efficient. Here are some fuel-saving measures: 1. Maintain speed: The most fuel-efficient driving condition is steady straight-line driving. The most fuel-efficient speed for small-displacement vehicles is 60-80 km/h, while for medium-displacement vehicles it's 80-100 km/h. Driving at the economic speed is the most fuel-efficient. 2. Gentle acceleration: Start in low gear and gently press the accelerator pedal for slow acceleration. When the car reaches a certain gear speed, learn to listen to the engine sound and gradually shift from low to high gear. This can reduce engine warm-up time and increase fuel utilization. Rapidly pressing the accelerator to accelerate when starting not only damages the car but also significantly increases fuel consumption.
