Does filling up the gas tank in summer affect the car?

[MakaylaDella]

Filling up the gas tank in summer does affect the car. Here are the specific details: 1. Driving safety: The car's fuel tank has a vent hole at the top. If the tank is filled to the brim, gasoline can easily overflow from the vent hole. 2. Tank deformation: The fuel tank has a fixed capacity, and leaving some space prevents gasoline expansion. If the tank is overfilled, gasoline will expand due to heat from the sun, which can deform the tank. 3. Vehicle performance: More gasoline increases the vehicle's weight, requiring the engine to consume more fuel to move the car. 4. Other effects: It can severely reduce the performance of the carbon canister, leading to engine shaking, increased fuel consumption, faster gasoline evaporation, and gasoline odors entering the cabin, which can harm health with long-term exposure.
