How to Open the Fuel Tank Cap of a Car?

[JeremiahLee]

Methods to open the fuel tank cap of a car include: 1. Mechanical key method, which is less common and typically found on some rugged off-road vehicles. Most household cars do not use this method as it is relatively complex; 2. Interior switch method, currently the most common way to open the fuel tank door, which is much more convenient compared to using a key; 3. Press-to-open method, the most convenient way currently, where the driver only needs to park the car and the fuel attendant can directly refuel. However, when not parked for refueling, the driver must ensure the central locking is engaged to prevent the fuel tank cap from being opened.
