Can oil be extracted from a sedan's fuel tank?

[JoshuaMarie]

Oil can be extracted from a sedan's fuel tank. The relevant maintenance content for the fuel tank is as follows: 1. Check for oil leaks: The maintenance of the fuel tank mainly involves combining it with the car's primary maintenance, draining accumulated water and sediment from the tank, and checking for oil leaks at the fuel pipe joints and switches. 2. Check for unobstructed air vents: For fuel tank caps equipped with air valves and steam valves, also check whether their ventilation holes are unobstructed. The filter screen at the fuel filler port should remain intact to prevent impurities from entering the tank during refueling and blocking the fuel lines. 3. Check the sealing gasket: The sealing gasket at the fuel filler cap should also be intact to prevent fuel from spilling out of the tank while driving.
