Why is there a gasoline smell in the car when there is no oil leakage?

[LeMatteo]

The reasons for a gasoline smell in the car when there is no oil leakage include poor sealing of the fuel tank cap, leakage at the gasoline pipe connections, or overfilling the fuel tank. When the fuel tank is overfilled, gasoline may overflow and enter the carbon canister through the pipes. The carbon canister is designed to collect gasoline vapors. If gasoline flows into the carbon canister, it will release excess gasoline vapors through the vent. If the car's air conditioning is in external circulation mode at this time, the gasoline smell can enter the car. Poor sealing of the fuel tank cap can be resolved by replacing the rubber gasket. Leakage at the gasoline pipe connections can allow gasoline vapors to enter the car through the air conditioning system. If there is a leak at the connections, dust may accumulate over time, forming an oily residue. The solution is to inspect the gasoline pipes. If the leak is at the connections, tightening them may solve the problem, or you can take the car to a repair shop for further inspection.
