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

[Beatrix]

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