How Often Should You Refuel a New Car?

Concise Answer: For a new car, it is generally recommended to refuel when the fuel gauge reaches the quarter tank mark. This practice helps maintain optimal fuel efficiency and engine performance.

Explanation:

The frequency of refueling a new car is crucial for maintaining fuel efficiency and ensuring the longevity of the vehicle. Refueling when the fuel gauge reaches the quarter tank mark is a common practice among automotive experts. This approach offers several benefits:

1. Fuel Efficiency: Regularly refueling when the tank is low can help maintain fuel efficiency. When the fuel level is low, the car's computer may adjust the fuel mixture to compensate for the lower fuel pressure, which can lead to increased fuel consumption. By refueling early, you can prevent these adjustments and maintain the car's fuel efficiency.

2. Engine Performance: Running the tank too low can cause the fuel pump to work harder, which can lead to increased wear and tear. By refueling when the tank is at the quarter mark, you can help ensure that the fuel pump operates efficiently and reduce the risk of damage.

3. Emissions: A low fuel level can also affect the car's emissions. When the fuel level is low, the engine may not run as cleanly, leading to higher emissions. Regular refueling can help keep emissions within acceptable limits.

According to a study by the U.S. Department of Energy, vehicles with a full tank of fuel can improve fuel efficiency by up to 2%. This is because the weight of the fuel adds stability to the vehicle, which can reduce drag and improve aerodynamics. Additionally, the study found that running the fuel tank below a quarter of a tank can result in a 10% decrease in fuel efficiency.

In conclusion, for a new car, it is advisable to refuel when the fuel gauge reaches the quarter tank mark. This practice helps maintain fuel efficiency, engine performance, and emissions levels. By following this guideline, drivers can ensure that their new car operates at its best.
