How to drive a car on the road is to add enough gasoline to it. I believe that since owning a car, people often go to gas stations and have more contact with gas station employees. Generally, refueling is done by employees themselves, and the owner is not very familiar with the car fuel tank cap. For example, the car fuel tank cap has these three hidden functions.

 

Firstly, we can see that there is a fuel label on the fuel tank cap of the car. I believe everyone knows what grade of gasoline their car is filled with, and they won't casually ask the staff to add the wrong fuel to their car. But if a friend borrows their own car, they are too lazy to ask, so just open the fuel tank cap and you'll know. The editor also reminds everyone that gasoline cannot be mixed and should not be added incorrectly.

In addition to the above two pieces of information, a drainage hole has also been installed on the car fuel tank cover. When refueling a car, it is very likely that gasoline will splash out and accumulate at the fuel tank opening. So the function of the drain hole is to discharge these liquids, after all, the accumulation of these liquids can cause some damage to the engine. Car owners should also clean this drain hole regularly.

 

Editor's comment: After reading it, everyone knows that there is so much information on the fuel tank cap of a car. When I first found out, I suddenly realized it. However, I don't usually know much about it myself. In fact, this information is quite important to us, such as how much fuel to add to our car, how much tire pressure it is, and so on.
