Will there be any problems with gasoline if the car is not driven for a long time?

There will be problems with gasoline if the car is not driven for a long time. Over time, the quality of gasoline deteriorates. If left unused for too long, the gasoline will oxidize and degrade, which may lead to incomplete combustion, carbon buildup, clogged fuel lines, unstable idling, and impaired engine performance, among other issues. Here are some precautions for using the fuel tank: 1. Do not wait until the fuel warning light comes on to refuel: Before driving, check the fuel gauge and calculate whether you need to refuel based on the distance of your trip and the fuel gauge reading. It is advisable to refuel in advance rather than waiting for the fuel light to come on. The fuel pump is located inside the tank and operates at high temperatures when continuously working. Being submerged in fuel helps to cool it effectively. When the fuel light comes on, it indicates that the fuel level is below the pump. Refueling only when the light is on will shorten the lifespan of the fuel pump, and having too little fuel in the tank may even cause the pump to burn out. 2. Choose to refuel in the morning or evening: Generally, temperatures are lower in the early morning and evening, and the vaporization point of gasoline is relatively low, so it is best to refuel during these times. Gasoline expands with heat and contracts with cold, and it is charged by volume. At lower temperatures, gasoline has a higher density, meaning the mass per unit volume increases, allowing you to get more fuel for the same price. 3. Avoid filling the tank completely when driving in the city: When driving in urban areas, there is no need to fill the tank completely. A full tank adds extra weight to the engine, increasing fuel consumption. Since refueling is convenient in the city, there is no need to fill the tank to the brim.
