Vehicles do not have safety mechanisms that prevent you from pumping gas into the gas tank when the engine is running. So if you’re asking can you put gas in a running car, the answer is yes. While you can pump gas with the car running, it doesn’t mean you should.

Is it dangerous to pump gas with the car on?

Technically, pumping gas when the engine is running is dangerous, and you should avoid it at all costs. It can lead to fire hazards.

The fire hazard will not emanate from the running car but from the conditions created when filling the gas on a running car. Refueling a running car allows gas vapor to escape the gas tank. If the fuel vapor comes in contact with heat and static electricity, it can lead to ignition.

Gas pumps feature a safety mechanism that stops the fuel nozzle from pumping when the tank is filled. However, there are chances that the mechanism may fail, allowing the fuel to pour on the ground when the tank is filled. If this occurs when the engine is running, the car will ignite.

Though this is rare, when you consider the possible outcomes, it’s best to follow simple instructions and shut off your vehicle engine before pumping gas. If you were asking, is it bad to pump gas with the car on? You now know the answer.

What will happen if you pump gas with the car on?

Now that I have answered the question, can I fuel my car with the engine running? You should understand that there are various risks associated with doing so.

The dangers that could happen with fuelling your car while the engine is running include spilling the fuel on yourself, spilling the fuel on the ground, static electricity, and, most dangerously, it can cause fire hazards.

I have seen several pictures and videos of fire hazards in gas stations. It is no joke. It can ruin the entire car and the gas stations. So, if you are asking, can your car explode if you leave it on while pumping gas? Your vehicle can ignite a fire and possibly lead to an explosion.

Static electricity

Gasoline is one of the most flammable liquids in cars. This means that if static electricity occurs, it can lead to flash fire. No doubt, you can quickly quench the flash fire, but if the car is running while pumping the gas, it can lead to a catastrophe.

Almost anything in your vehicle can generate static electricity. Coming out or entering the car can cause it. However, the possibility of getting to the gasoline is slim. But pumping gas with the engine running increases the chances of static electricity and fire hazards.

Spilling gas on yourself

Undoubtedly, gasoline does not have a good smell. So you don’t want to spill it on your clothes while pumping gas at a self-serve gas station. Aside from the scent, gasoline is a highly flammable liquid. Of course, you don’t want to catch fire for any reason.

Spilling gas on the car

You don’t want to spill gas on your car. Even if you disengage the gear while filling the gas, if there’s a sudden movement or the car rolls, no matter how small, while putting the noddles of the fuel door, there will be gas spillage on the car.

Fuel nozzles feature splash guards, but it is not 100% guaranteed. Fuel spillage on your car increases the chances of fire hazards or will, at least, damage your car paint.

Fire hazards

The most dreaded risk that you see these warning signs at every gas station is a fire hazard. This is true because the internal combustion process of an engine relies on gasoline. And if a spark catches the fuel, the entire car, gas pump, and gas station building will catch fire.

But here’s the thing; according to Mythbusters pumping gas while the car is running Reddit discussion and some YouTubers, the chances of your car catching fire are slim. However, you can’t rule it out because it’ll lead to an inferno if it happens. Gasoline and fire will cause a large fire, but if the engine is running when it happens, it’ll make it uncontrollable.
