summer
Don't say these two words to the cheerers:
"Full"
The main reason is that everyone knows the principle of thermal expansion and contraction, if the oil is too full in the hot summer, the oil is likely to overflow from the ventilation hole, once it encounters an open flame, it is easy to cause a fire, and even an explosion will occur in serious cases.
so
It's winter now
Is it possible to fill up the oil?
Winter refueling should not be too full
01
Easily clogging ventilation holes
Winter, like summer, refueling still can't be filled. On the one hand, when the oil is too full, it may overflow from the ventilation hole, which is easy to cause danger; on the other hand, the oil is too full and it is easy to block the ventilation hole.
I don't know if you have ever experienced the situation that the car can't catch fire when it has just finished refueling, or the situation where the car is running at high speed jumps and jumps? This may be caused by refueling too much.
Once the ventilation hole is blocked, negative pressure will occur in the fuel tank, resulting in poor oil supply or even no oil supply.
02
May damage the charcoal tank
Adding too much oil can also cause harm to the charcoal tank. The carbon tank is generally installed between the fuel tank and the engine. Gasoline is a volatile liquid, and there is often steam in the tank at room temperature. If the fuel is too full, gasoline will enter the carbon tank as a liquid instead of steam, causing damage to the carbon tank.
03
Gasoline spoilage affects the car
In fact, our gasoline has a shelf life, especially ethanol gasoline, which has a relatively short shelf life. If you fill up too much fuel and you don't use the car very often and can't run out of oil during the shelf life, then gasoline spoilage can also have a certain adverse effect on the car.
