Does the fuel gauge E indicate full or empty?
1 Answers
In a car's fuel gauge, F stands for full, and E indicates low fuel level. For an analog fuel gauge, when the needle points to F, it means the fuel tank is full. The closer the needle is to E, the lower the fuel level, meaning there is less fuel. F represents full, which is short for "FULL". The F on a car's fuel gauge stands for FULL in English, indicating a full tank, while E stands for Empty, meaning low fuel. Precautions for refueling a car: Avoid overfilling: If the tank is filled too much, the high summer temperatures and the heat generated by the car itself can cause the fuel to expand. To prevent the fuel tank from rupturing due to the expansion of fuel volume, there is a vent hole on top. If the tank is overfilled, fuel may overflow through the vent hole, which could lead to spontaneous combustion if exposed to an open flame, with potentially disastrous consequences. Additionally, fuel overflowing through the vent hole may drip onto the car body, causing some corrosion. Try to avoid waiting until the fuel light comes on to refuel: While driving, always pay attention to the fuel gauge. When the needle indicates only a quarter of the fuel is left, it's time to refuel. It's best not to wait until the fuel light comes on before refueling. Modern cars use electric fuel pumps that rely on fuel for lubrication and cooling. Frequently waiting until the fuel light comes on to refuel can prevent the fuel pump from getting proper lubrication and cooling, ultimately reducing its lifespan. Choose the right time to refuel: Avoid refueling at midday. Due to thermal expansion and contraction, the volume of fuel increases with rising temperatures and decreases when temperatures drop. Since fuel is sold by volume, to save money, it's better to refuel in the early morning or evening.
