When is the appropriate time to refuel a car based on remaining gasoline?

It is appropriate to refuel when the car has 7 to 10 liters of gasoline remaining. Refueling timing: When within 30 kilometers, it's best to wait until the fuel gauge light comes on before refueling. The fuel gauge light indicates that the fuel tank is almost empty, and there is generally a range of about 7-10 liters remaining when the light comes on. If you are on a highway or in a remote area, you can refuel when the fuel level in the tank is about one-quarter full. Impact of low fuel: When the remaining fuel in the tank is very low, it can affect fuel supply. This is because the vehicle experiences vibrations or tilts while driving, causing the fuel surface to fluctuate along with the car. However, the fuel pump is fixed inside the tank, and there might be brief moments when it cannot draw fuel. Power output can also be affected: if fuel does not flow smoothly into the fuel line, it can disrupt the engine's normal operation, leading to unstable power output.
Regarding how much gasoline should be left before refueling, my experience suggests it's best not to wait until the fuel light comes on. After driving for so many years, I've seen many cars develop problems due to extremely low fuel levels, especially since the fuel pump relies on gasoline for cooling and lubrication. When the tank is nearly empty, the pump is prone to overheating and damage. Sediments accumulated at the bottom may also be drawn into the system. I recommend refueling when the gauge drops to the one-quarter mark—this protects the engine and saves hassle. This is particularly important during long trips or when weather conditions fluctuate, as refueling in advance ensures greater safety. Develop a habit of regular checks, such as glancing at the fuel gauge after each car wash, to avoid breakdowns and extend your vehicle's lifespan. In summary, it's better to be cautious and not push the limits.
From a cost-saving perspective, the timing of refueling is quite strategic. Avoid frequent trips to the gas station; it's best to refuel when the tank is half full because an empty tank is too light and can actually waste fuel. Plan your trips carefully—for city driving, refill when you're down to a quarter tank. Fuel pumps that constantly draw from the bottom of the tank can pick up impurities, affecting engine efficiency. I often plan based on my commute route, keeping my monthly fuel card budget in check, and refueling when about 10% remains to avoid waste. During winter or peak periods when fuel supply is tight, it's even more important to refuel in advance. Regularly monitor your fuel consumption gauge and combine it with navigation distance to save a little money effortlessly. Don't wait until the low fuel light comes on to scramble for a refill.
Safety first, driving with very little fuel left is quite dangerous. If the fuel level is too low and you encounter traffic or a breakdown, you'll be left helpless. The fuel system relies on fuel for cooling, and the pump can overheat when levels are low. You should refuel when it reaches 15%, don't wait until the warning light comes on. I've seen a friend's car break down on the road, wasting time and effort. Maintaining a moderate fuel level, especially in remote areas or during rain or snow, allows for emergency handling. Develop the habit of checking the fuel gauge before each ignition to ensure you have enough for common distances. A simple action can prevent major trouble.
