How Many Kilometers Can You Drive with a Quarter Tank of Fuel?
1 Answers
A quarter tank of fuel can typically last for about 200 kilometers. However, if the fuel level is too low, it may damage the fuel pump. The fuel pump is located at the bottom of the fuel tank and starts working as soon as the car is turned on. The heat generated by the fuel pump is cooled by the gasoline in the tank. If the fuel level is too low, the fuel pump becomes exposed, meaning it is not submerged in gasoline, which can cause it to overheat and eventually burn out. Therefore, it is advisable to maintain at least a quarter tank of fuel and refuel promptly when the level drops below this threshold. Below are some additional insights: 1. Choosing the Right Gasoline: The octane rating of gasoline indicates the proportion of iso-octane, which has good anti-knock properties. For example, 95-octane gasoline contains about 95% iso-octane and 5% n-heptane, which has poor anti-knock properties. Higher octane ratings indicate better anti-knock performance. It is recommended to follow the fuel grade specified in the vehicle's manual or the label inside the fuel tank cap. 2. Precautions: Many car owners tend to fill the fuel tank to the brim or until the pump automatically stops. However, this can be risky, especially in summer, as fuel expands due to thermal expansion and may overflow. Overfilling can also damage the carbon canister, as excess fuel may flow into it along with fuel vapors, causing malfunctions. A damaged carbon canister cannot filter fuel vapors effectively, allowing gasoline to enter the vehicle's interior, which is hazardous.
