Refuelling a car may seem like a routine task, but many drivers wonder whether it is safe or even legal to leave the engine running while doing so. The risks linked to fuel vapours, static electricity, and hot components make this a serious safety concern. This guide answers common questions, highlights potential dangers, and lists the dos and don’ts you should follow at the pump.
Is it safe to refuel while the engine is running?
Technically, vehicles can be refuelled while the engine is running. However, it is strongly discouraged. Fuel stations, safety bodies, and vehicle manufacturers advise turning the engine off before filling up to reduce unnecessary risks.
Can refuelling with the engine running cause a fire or explosion?
Yes. Petrol and diesel emit highly flammable vapours. If these vapours meet sparks, static discharge, or hot car components, they can ignite. Though rare, such incidents can cause serious fires or explosions.
Is it illegal to pump fuel with the engine running?
In many countries, regulations or fire codes require that the engine must be switched off during refuelling. While enforcement differs, failing to follow rules can lead to fines, liability issues, or invalid insurance claims.
What do manufacturers and fuel stations recommend?
Most vehicle manuals state clearly that the engine should be switched off during refuelling. Fuel stations display warning signs instructing drivers to do the same. Following these guidelines avoids mechanical issues and protects warranties.
What are the risks beyond fire hazards?
- Health risks: Inhaling fuel vapours may cause dizziness, nausea, and long-term health effects.
- Environmental damage: Fuel spillage pollutes soil and water, while vapours add to air pollution.
- Vehicle issues: Leaving the engine on during refuelling can affect emission systems or trigger warning lights.
- Insurance and warranty: Claims may be rejected if unsafe practices caused an incident.
What if you must refuel with the engine running?
In rare cases, such as extreme weather or vehicles that may not restart, some precautions help reduce risk:
- Keep the car in park with the handbrake engaged.
- Avoid smoking, flames, or electrical activity nearby.
- Do not leave the pump unattended.
- Reduce static by touching metal before handling the nozzle.
- Finish refuelling quickly and avoid overfilling.
Dos and Don’ts of Refuelling
| Do’s | Don’ts |
| Always turn off the engine before pumping fuel. | Don’t refuel with the engine running. |
| Follow fuel station safety instructions. | Don’t smoke or use open flames nearby. |
| Stay at the pump while refuelling. | Don’t re-enter the car repeatedly (static risk). |
| Allow automatic shut-off to stop fuelling. | Don’t “top off” the tank. |
| Check your vehicle manual for safety guidelines. | Don’t ignore signs or warnings at the station. |
While it may seem harmless, refuelling with the engine running carries real risks. Fires, explosions, health hazards, and insurance issues are possible outcomes. The safest practice is simple: always switch off your engine before filling your tank.

FAQs
Is it safe to pump gas with the engine running?
No, it is not safe. Fuel vapours are flammable, and the heat or sparks from a running engine can cause fire or explosion. Always switch off before refuelling.
Can you get fined for refuelling with the engine on?
Yes, in many countries, it is against fuel station rules or local fire codes. Fines or penalties may apply if caught, and insurance claims may be denied in case of accidents.
Why do petrol stations ask to turn off the engine?
It reduces the risk of fuel vapours igniting. A running engine, hot exhaust, or static spark could easily start a fire. Turning the engine off is a simple but crucial safety measure.
What happens if you forget to turn off your car while refuelling?
Most of the time, nothing happens. However, you are exposed to fire hazards, fuel spillage risks, and potential legal or insurance issues if an accident occurs while the engine is left running.
Can refuelling with the engine running damage the car?
Yes, in some cases. It can affect the emission control system, trigger warning lights, or even impact warranties. Manufacturers advise turning off the engine to avoid unnecessary strain and safety concerns.
