Why Does My Car Always Have a Gasoline Smell?

[VanDawson]

Here are the possible reasons why your car always has a gasoline smell: 1. Reason one: The smell only occurs when starting the cold engine in the morning and disappears after a while, especially noticeable in enclosed, windless environments like garages. This phenomenon is normal and does not require any maintenance or inspection, as it is caused by incomplete combustion. 2. Reason two: The gasoline smell comes and goes, regardless of whether the engine is cold or hot. This could be due to a loose fuel tank cap or aging/cracked carbon canister pipes, leading to gasoline vapor leakage. 3. Reason three: The gasoline smell is persistent and strong. This indicates a gasoline leak, which requires immediate inspection and repair. The leak could be from the fuel pump's outlet or return pipes or other connection points.
