Can You Fill a Car with the Engine Running?
Yes, but it’s not recommended
It’s possible to fill a car with the engine running, but it’s not recommended. Here’s why:
- Fire hazard: Gasoline is highly flammable, and the fumes can easily ignite. If the engine is running, the exhaust system is hot, and there’s a risk that the fumes could come into contact with the exhaust and ignite.
- Damage to the engine: If the gas tank is overfilled, the gasoline can get into the engine and damage it.
- Vapor lock: If the engine is running and the gas tank is filled too quickly, the gasoline can vaporize and cause vapor lock. This can prevent the engine from starting or running properly.
When it’s okay to fill a car with the engine running
There are a few situations where it may be necessary to fill a car with the engine running. For example:
- If you’re in a hurry and don’t have time to turn off the engine.
- If you’re at a gas station that doesn’t have a self-service option.
- If you’re filling a car that has a diesel engine.
