Why should you keep your gas tank no lower than a quarter of a tank?

Keeping your gas tank no lower than a quarter of a tank is primarily important because it helps to avoid potential issues related to sediment and condensation within the fuel system. When the fuel level is low, the fuel pump may draw in sediment that has settled at the bottom of the tank, which can clog fuel filters and injectors. Additionally, a low fuel level increases the chances of condensation forming inside the tank, especially in cooler temperatures. This moisture can lead to water mixing with the fuel, causing performance issues and potential engine problems.

While the other options address important aspects of fuel management and engine performance, they do not focus on the technical and maintenance-related reasoning behind why maintaining at least a quarter tank is recommended. Properly managing fuel levels can contribute to the longevity and efficiency of the fuel system overall.
