Is it true that refueling should be performed when vehicles are below 1/4 tank?

The statement that refueling should be performed when vehicles are below 1/4 tank is indeed true. This practice is essential for several reasons. Maintaining fuel levels above a quarter tank helps prevent the fuel pump from overheating and ensures that sediment in the bottom of the tank does not enter the fuel system, which can lead to engine issues. Additionally, keeping the tank filled reduces the risk of running out of fuel in the middle of operations, which could compromise mission effectiveness and safety.

While it's important to consider the operational context and potential for emergencies, regular refueling when below the 1/4 mark is a proactive approach to maintenance and readiness. This practice contributes to a smoother and more reliable operation of the vehicles, ensuring that they are always ready for action when needed.
