Do You Have To Turn Your Car Off When Getting Gas

Can I Fuel My Car With Engine Running?

Yes, you can pump fuel in your vehicle with your engine running. However, it does not mean that you should. If you pump fuel in your car with the engine running, there might be a slight chance of a fire if you leave your vehicle’s engine running. 

With your engine running, this will increase the chance of gas vapors igniting if they ever come in contact with some static electricity. So that is why it is the best and the safest move to turn off your vehicle when getting gas. This is so you can avoid the danger of having a fire, check engine light, and even static electricity. 

There is a fire risk because the fumes can burn but not the liquid. And this can cause a dangerous explosion. As a result, you must remember that if you fuel up, you will have to shut the car off and then leave the car off while getting gas. 

You also need to unplug any devices that you might be charging. Do not worry because you can always plug them back once you are done gas pumping. It would be best to do some other safety precautions like not vape or smoke when getting a pump. 

You should not also use any phone. Static electricity can be created while on the phone, so you need to leave your phone in your car.

What Happens If You Accidentally Leave Your Car Running While Pumping Gas?

There are only a very few accidents in a gas station that involves static electricity. So if you have left your vehicle running while you are pumping gas, then there can be a possibility of a fire, but it is very unlikely. But it can also have some issues and might even provide some damages to your car. 

Yes, getting gas while the engine is turned on might not cause significant damage and will not do any bad things to your car, but it can turn the engine light on. Some vehicles have that feature to detect even a minimal gasoline vapor leaking from the fuel tank, the engine, or the fuel lines. If you stick the nozzle to have it fill up, you will open the gas tank, usually closed and sealed. 

This will then allow the vapors of the gasoline to escape. The computer in your car will then detect a vapor leak and turn and trigger that check engine light. Some people also say that nothing bad will probably happen aside from turning on the check engine light. 

The pressure sensors will detect that the gas cap is turned off even while the engine is running in an explosion; it is very unlikely. There will not be enough air or oxygen to ignite combustion or an explosion. Many vehicles have a fuel pump inside their tank, and it is submerged with fuel. 

It also has an electric motor part that is also submerged in fuel for cooling and lubrication. If the vapor mixture inside the tank is combustible, running the fuel pump with the tank almost empty can cause a fire. You should know that every rule and regulation is not made for nothing. 

If there is a rule about this, it must be followed because it is for the safety of the people. So if you decide to leave your car engine on when getting a gas pump, you should be fully aware that you are not following the rules and that you are going against one of the safety precautions made in getting a gas pump.

Can Your Car Explode If You Leave It On While Pumping Gas?

Having an explosion in a gas station because of leaving the car engine on is pretty unlikely. But we are on the safe side of the argument. We have to ensure our safety and the people we are with while having your gas pump. 

Just because an explosion is very unlikely, it does not mean that it is impossible. It can still happen. So yes, leaving your vehicle while pumping gas can cause an explosion, but it can be very unlikely. 

This is because gasoline is highly flammable. You will need a spark to make the vehicle ablaze and explode. This incident might be sporadic, but it does happen.


In summary, many car drivers have been asking whether it is dangerous to leave your car, on the whole, getting a gas pump. Of course, you can have a gas pump while your engine is running. However, it is against the rules and the standards of a gas station. 

This is for the safety of all the drivers and the people around. Leaving your vehicle on while having a gas pump can cause an explosion and can be dangerous.
