Should You Fill Up the Tank for the First Time?

[OCole]

When refueling a new car for the first time, it is not recommended to fill the tank completely. Here are the details: 1. Reason: For the first refueling after purchasing a new car, it is best to stop when the fuel pump automatically shuts off (first click). At this point, the tank is not actually full. This leaves some air in the tank to prevent excessive internal pressure. Additionally, this method helps verify the accuracy of the fuel gauge in the new car. However, if you continue to refuel after the first click, the fuel level float will rise with the fuel surface, potentially stretching the fuel level sensor's contacts and sliding piece toward the edge or even causing them to disconnect. This could trigger a fault alarm from the fuel level indicator. 2. Maintenance: Refueling in the early morning or evening is more economical than refueling at noon. This is especially true during seasons with significant temperature differences between day and night, such as autumn, due to the principle of thermal expansion and contraction. Since fuel is measured by volume, the lower temperatures in the morning and evening result in a relatively smaller volume, while the higher temperatures at noon cause the volume to expand.
