How Much Fuel Should You Add to Your Car at One Time?

When refueling your car, try not to exceed the safe capacity to avoid vehicle damage. Below is relevant information about car refueling:1. The accuracy of the fuel amount cannot be judged based on the rated capacity of the fuel tank. Because a car fuel tank is a container (it is not managed as a measuring instrument by the state) rather than a measuring instrument, it cannot be used as a basis for judging measurement accuracy. According to the requirements of relevant national mandatory standards, the rated capacity of a car fuel tank should be controlled at 95% of the maximum safe capacity.2. The engine must be turned off when refueling. Since gasoline is a flammable item and has volatile characteristics, when the concentration of gasoline molecules in the air reaches a certain level, there is a possibility of combustion or explosion upon encountering a spark.
I've been driving for many years and always feel that filling up the gas tank completely is the most worry-free approach when refueling. This not only reduces the hassle of frequent trips to the gas station but also keeps the fuel pump submerged in the fuel, preventing overheating and extending its lifespan. Some might argue that filling half the tank can reduce weight and save a bit of fuel, but the benefits are too minimal compared to the time and effort saved. Especially on long trips, a full tank allows me to focus on driving without worrying about finding a gas station at any moment. Additionally, in extreme winter or summer weather, a shallow fuel tank may lead to moisture or debris accumulation, affecting engine performance. Overall, developing the habit of filling up every time is quite practical for daily maintenance.
From a cost-saving perspective, I prefer adding a fixed amount, such as spending around 300 yuan each time. This makes it easier to control the budget and avoid impulsive spending, especially when fuel prices fluctuate significantly. However, don't add too little—less than half a tank will increase the number of trips to the gas station, and each extra drive consumes additional fuel, which can actually waste money. The ideal approach is to combine it with your driving distance. For short commutes, filling half a tank is sufficient; for long-distance driving, filling up is more cost-effective. Additionally, considering environmental factors, refueling less frequently means more frequent production of bottled gasoline, which slightly increases carbon emissions. Therefore, I recommend adjusting based on actual needs to balance economy and convenience.
