Does E or F indicate a full fuel tank?

In a car's fuel gauge, F stands for 'FULL', indicating the tank is full. The F on the fuel gauge is derived from the English word 'FULL', signifying a full tank, which can be translated as full or complete. E stands for 'Empty', representing low fuel. When the needle points towards the F, it means there is more fuel, and the closer it is to E, the less fuel remains. Many car fuel gauges also have a red mark near the E, indicating that the tank is almost empty and should be refueled promptly. Do not wait until the warning light comes on to refuel: This is because the fuel pump is located inside the fuel tank and relies on gasoline for cooling and lubrication. Insufficient fuel can hinder the proper operation of the fuel pump and reduce its lifespan. It is not advisable to fill the tank completely when refueling: This is because gasoline expands when heated and evaporates into gasoline vapor under high temperatures in summer, requiring space to accommodate this. If the tank is filled to the brim without any space, gasoline vapor or even liquid gasoline may enter the carbon canister for storage. Once the carbon canister is full, the excess may escape into the air, leading to both waste and environmental pollution.
When I bought my first car, I asked a similar question. The E on the fuel gauge stands for Empty, meaning the tank is empty, and F stands for Full, indicating it's full. When the needle is close to F, it means there's plenty of fuel, and the middle position roughly indicates half a tank. Beginners often misunderstand this—I initially thought E meant full, and once I was shocked to realize the tank was almost empty. Remember to develop the habit of refueling when the fuel level drops to a quarter to avoid breaking down on the road and to protect the fuel pump. Running out of gas increases component wear, especially in city driving where frequent starts and stops require extra attention. The car manual also provides detailed explanations. If the fuel gauge is inaccurate, it might be a sensor malfunction, so get it checked immediately.
