Why is there a gasoline smell outside the car after parking?

[Alex]

After parking, the smell of gasoline outside the car could be due to engine oil leakage, spark plug oil leakage, or fuel injector leakage. Unusual odors inside the car can be identified through the following: Strong gasoline smell: Mostly caused by fuel system leaks. Musty smell: Bacterial growth in the evaporator and air ducts due to prolonged lack of cleaning in the air conditioning system, requiring cleaning. Burnt rubber smell: Possibly caused by frequent emergency braking leading to overheated tires. Resin-like burnt smell: Caused by prolonged friction of brake pads, possibly due to an engaged handbrake, incomplete separation of friction pads and brake discs, or long-distance braking causing overheating. Pungent foul smell: Dirty or poor-quality engine oil, clogged air filters, or broken cylinder piston rings, or possibly exhaust emissions. Burnt plastic smell: Mostly caused by short circuits in the electrical system burning the wire insulation.
