How to Open the Fuel Tank Cap of a Sedan?

[LaBrady]

There are several methods to open the fuel tank cap of a sedan: 1. Use a mechanical key to twist it open; 2. Press the fuel tank cap switch inside the car; 3. Press the fuel tank cap to open it. The fuel tank of a sedan is a container made of stainless steel, designed to store gasoline, featuring good sealing. It consists of a fuel filler pipe, tank body, fuel tank cap, fuel gauge, and fuel pump. Notes on refueling: 1. Refuel in the morning or evening when the temperature is relatively low, as gasoline of the same volume can have a higher mass; 2. Avoid filling the tank completely when driving in the city, as it increases the engine's load; 3. Do not wait until the tank is empty to refuel, as insufficient fuel not covering the fuel pump can shorten its lifespan; 4. Avoid refueling during thunderstorms, as the fuel nozzle might introduce stray currents into the fuel tank, exacerbating the movement of unstable gasoline molecules and posing fire and explosion hazards.
