Is it unsafe to fill up the gas tank in summer?

[DallasFitz]

It is not advisable to fill up the gas tank completely in summer, as doing so can not only cause damage to the vehicle and disrupt the normal operation of the engine, but also pose a risk of fire or explosion. Additional information: 1. A full gas tank can easily block the vent hole. Once the vent hole is blocked, negative pressure will form inside the tank, leading to poor fuel supply or even a complete lack of fuel. This can result in the vehicle failing to start immediately after refueling. 2. When driving on highways, a full tank can cause jerky movements, making the ride uncomfortable for both the driver and passengers. Moreover, if the tank is overfilled, especially in summer, gasoline vapors may not form properly. These vapors can directly enter the carbon canister through the fuel components, potentially damaging it.
