What is the fuel consumption of the Regal?

The average fuel consumption of the Regal is 9.07L/100km. The fuel consumption of a car varies slightly depending on each individual's driving habits and skills. If the driving habits are relatively smooth, the fuel consumption will be lower. However, if you prefer aggressive driving, overtaking, and other high-RPM operations, the fuel consumption will increase accordingly. Here are some methods to save fuel: Maintain a steady speed: Control the vehicle's speed while driving and avoid sudden braking. Avoid opening windows at high speeds: Opening windows at high speeds will increase fuel consumption. Regularly check tire pressure: Ensure the tire pressure is correct, as both underinflation and overinflation will increase fuel consumption. Therefore, it is necessary to check tire pressure regularly. Pay attention to transmission maintenance: Always use the correct transmission oil for your vehicle. Transmission oil not only lubricates but also plays a role in transmitting torque, so it should be replaced periodically.
