Can a car be used to extract oil?

The fuel inlet of a car's fuel tank is a curved pipe, making it impossible to extract oil from there. However, by opening the rear seat cushion of the car, you can find an access point to do so. Gasoline is a volatile and flammable hydrocarbon mixture liquid derived from the distillation and cracking of petroleum, used as fuel. It appears as a transparent liquid, is flammable, and has a distillation range of 30°C to 220°C. Its main components are C5 to C12 aliphatic hydrocarbons and cycloalkanes, along with a certain amount of aromatic hydrocarbons. Gasoline has a high octane number (anti-knock combustion performance) and is classified into different grades based on octane ratings, such as 89, 90, 92, 93, 95, 97, and 98. Starting from January 2012, the gasoline grades 90, 93, and 97 were revised to 89, 92, and 95 respectively.
Seeing the question about siphoning gas from a car, I really don't recommend doing it yourself. Older carburetor-equipped cars could indeed be siphoned, but modern fuel-injected cars have anti-siphon designs in their fuel tanks. Forcing a tube in can not only damage the car but, more importantly, it's extremely dangerous. Gasoline is highly volatile—just a little static spark from plastic tubing rubbing could cause serious trouble. Last month at a friend's shop, a car owner tried using a laundry detergent bottle to catch gas, and static electricity nearly set the garage on fire. If you're really in an emergency, it's better to call professional roadside assistance for fuel delivery or ask a repair shop to use a vacuum fuel extractor—at least they have explosion-proof equipment. Remember: gas stations won't even fill metal containers, and that rule definitely exists for a good reason.
