How Much Fuel Should Be Left in the Car Tank Before Refueling?
1 Answers
It is appropriate to refuel when there is a quarter of the fuel left in the car tank. If the fuel level drops below a quarter, it may affect the cooling capability of the fuel pump. The fuel consumption of a car is influenced by factors such as engine displacement, tire size specifications, and vehicle weight. According to physics principles, under unchanged conditions, the greater the weight of the car, the greater the resistance encountered during driving, leading to increased engine load and consequently higher fuel consumption. When refueling, it is not advisable to fill the tank completely. A full tank increases the vehicle's load, affects the tank's air intake, raises energy consumption, reduces the carbon canister's efficiency, and may even cause the carbon filter to fail.
