Car Smells Like Gas
A raw fuel smell is a safety issue, not a nuisance. It can be an EVAP vapor leak or an actual liquid leak, and the second one is a fire risk.
What it feels like
- A strong gasoline smell around the filler neck after refueling
- The smell follows you into the cabin while driving
- A faint fuel odor in the garage overnight
- The check engine light on with no drivability change

Stop and get it looked at if
