The American Automobile Association (AAA) recommends that fuel tanks should always be kept full, especially during winter, to reduce condensation. However, constantly filling the tank to the brim can be time-consuming and is not the ideal solution. Mechanics suggest that keeping the fuel level between one-quarter and full is optimal. Maintaining at least a quarter tank protects the fuel pump and decreases the likelihood of running out of fuel on the road, while overfilling the tank can lead to other issues for the car.

In winter conditions, mechanics have additional advice for drivers. They recommend ensuring that the fuel level is kept above half a tank when inclement weather is forecasted. This precaution helps to ensure that drivers have enough fuel to last in the event of delays or emergencies caused by bad weather, enabling them to stay safe on the road.

Overall, while it may seem inconvenient to keep the fuel level monitored, following these tips can prolong the life of the vehicle's fuel system, ensure drivers have enough fuel in case of unexpected situations, and promote safer driving practices, especially in winter months when road conditions can become treacherous.
