Should the first refueling of a new car be filled to the maximum?

For the first refueling, it is essential to add as much fuel as possible, filling it until the fuel gun "clicks off." This helps verify the accuracy of the new car's fuel gauge and establishes a foundation for future refueling. Detailed explanations are as follows: Fuel quantity: Apart from filling up the tank for the first refueling, try to avoid filling it completely in subsequent refueling sessions. A full tank's weight is equivalent to carrying an additional adult in the car, which increases fuel consumption, making it neither economical nor environmentally friendly. Therefore, only the first refueling should be a full tank, and subsequent refuelings should be limited to half a tank. Timing of refueling: For new cars, it is advisable to refuel in the morning, especially during summer. Cooler morning temperatures and shorter engine startup times effectively prevent reduced fuel intake due to excessive gas in the tank. Prompt refueling: When the fuel gauge warning light comes on in a new car, refuel immediately. Otherwise, insufficient gasoline in the tank may prevent the fuel pump from cooling, leading to its burnout. This point is crucial.

It's best to fill up the tank for the first time when refueling a new car. Based on my years of driving experience, a full tank helps the fuel system of a new car operate more smoothly. When a new car leaves the factory, there may be small residues or air in the fuel tank. Filling it up helps flush the pipelines, ensuring the fuel pump is well lubricated and operates without wear. Especially during the break-in period, a full tank provides stable fuel supply, allowing the engine to run smoothly and enhance performance. Imagine how convenient it is to have plenty of fuel for long trips, avoiding frequent stops at gas stations. Of course, don't overfill to the point of spillage; modern fuel tanks are well-sealed with built-in expansion space, unlike older cars that were prone to fuel leaks and odors. My habit is to fill up the tank right after taking delivery of a new car to test the fuel gauge's accuracy, then drive normally to observe fuel consumption, which aids in long-term maintenance.

From a practical cost-saving perspective, I believe the first refuel doesn't necessarily need to be a full tank. When getting a new car with very low fuel level, I'd suggest filling it halfway first and test driving for a day to confirm the fuel gauge displays correctly, avoiding unnecessary expenses. A full tank might cost dozens of yuan extra in gasoline fees, especially in summer when fuel evaporation causes greater waste. Moderate refueling also offers more flexibility - if encountering poor-quality fuel at a station, you can switch to better fuel elsewhere to protect the new engine. Regular refueling to maintain moderate fuel levels benefits the fuel pump by preventing dry running damage; modern vehicles' electronic systems are precise enough without needing full-tank calibration. For daily commuting, half a tank is sufficient for time and cost efficiency, with smooth driving being key during the break-in period rather than using additives.

Buying a new car is exciting yet nerve-wracking, and I struggled with my first refueling. The salesperson recommended filling up to check if the fuel system was functioning properly, so I went to the gas station and filled the tank to observe the fuel gauge's accurate movement and ensure the engine started smoothly. However, overfilling may lead to thermal expansion, leakage, pollution, or safety hazards; I opted to fill it to 80% capacity to leave some room. Beginners often make mistakes like frequently driving with low fuel levels, which can damage the fuel pump's lifespan. During the initial phase of a new car, fueling appropriately helps cultivate good habits. Choosing reputable gas stations with high-quality fuel is better for new cars, and additives are unnecessary. During the break-in period, maintaining steady refueling and avoiding aggressive driving is key.
