Serious mistake of letting car gas tank run out before filling up

Cars that suddenly die can cause accidents.

Continuous operation of the vehicle with a low fuel level may cause sediment to form at the bottom of the tank.

Many drivers have a bad habit of "lazy to fill up" and let the gas tank run out before refueling. If you continuously operate the car while leaving the gas tank low, sediment can form at the bottom of the tank.

Especially when driving on crowded roads with lots of vehicles, an empty gas tank can cause the engine to suddenly stop, which can lead to unfortunate consequences.

Impact on car engine

Letting the car's gas tank run out before filling up is dangerous beyond imagination.

Driving a car with almost no gas is bad for the engine. However, many people still make this mistake and have not been able to give up this habit.

May damage fuel pump.

According to experience, if the driver runs when the fuel tank is below the E mark, it will lead to the fuel pump failure. In fact, the fuel pump is an important part of the pumping system, responsible for transferring fuel from the tank to the combustion chamber. When operating in a state of low fuel, many parts will be seriously damaged, especially the filter and motor.

Internal structure of car fuel pump.

Accordingly, the electric motor is usually cooled by gasoline when the car is moving with a full fuel tank. The car needs a circular fuel pump to transport gasoline to the engine.

At this time, the fuel will cool the copper coils. When the gasoline runs out, air automatically replaces the liquid through the fuel pump to cool the copper coils, causing the electric motor to overheat and damage the vehicle.

In addition, the residue in the empty fuel tank is also sucked into the pump to supply the engine. This situation occurs many times will cause the engine to gradually corrode and operate poorly.

Therefore, to avoid risks, car owners need to fill up gas before it runs out and regularly take care of and maintain the car to prolong its life and operate durably over time.

You should fill up the tank when there is at least 1/4 of gas left to avoid running out of fuel. You should keep the tank full before each long trip or on crowded roads or roads with frequent traffic jams. Use smart mobile devices to find the nearest gas station instead of having to drive around to fill up. This helps drivers save time as well as fuel costs for their "baby car".
