There are many reasons why you should turn off your car engine when fuelling. The primary concern is safety, as static electricity from the friction of the motor running can cause a spark that ignites gasoline vapours, potentially leading to a fire. While this is rare, it is still a risk, and it's better to be safe than sorry. Additionally, it is essential to stay alert and focused while pumping gas to avoid overfilling the tank, which can be costly and cause issues with your vehicle. Getting back into the car while fuelling increases the risk of static electricity, and smoking near the pump is a fire hazard.
| Characteristics | Values |
|---|---|
| Safety | Static electricity from the car battery or friction of the motor running can ignite gasoline vapors, causing a fire. |
| Safety | Potential accident igniters include power sources for phone chargers and cigarette lighters. |
| Safety | Children may inadvertently engage the drive gear and move the car with the fueling nozzle still in the tank, leading to a lethal accident. |
| Safety | The system may ingest liquid fuel, causing it to malfunction or smash. |
| Safety | The car may be driven away with the hosepipe still attached, causing a spill and increasing the risk of fire. |
| Convenience | It is dangerous and inconvenient to perform operations such as opening the bonnet or checking the oil with a running engine. |
| Convenience | The fuel gauge may malfunction if the engine is left running during refueling. |

Static electricity
The risk of fire is increased when a person gets back into their car during refueling. This is because static electricity can build up as a person moves around in their car, and this charge can then be released at the nozzle when they exit the vehicle and resume fueling. This risk is heightened for people wearing synthetic fabrics, such as women's clothing and hosiery, which are more prone to static build-up when in contact with vehicle upholstery fabrics.
To prevent static electricity fires, it is recommended that motorists touch a metal part of their vehicle, such as the car door or a different gas pump, before touching the gas nozzle when exiting the vehicle. It is also advised to avoid getting back into the car during refueling altogether. If this is unavoidable, one should again touch a metal part of the car away from the filling point before touching the nozzle when exiting the vehicle. Additionally, it is important to always turn off the engine when refueling, as a running engine can create sparks that could potentially ignite gasoline vapors.
While the risk of a static electricity fire is rare, it is important to know what to do in case a flash fire occurs. If this happens, it is recommended to leave the nozzle in the vehicle and back away. Then, shut off the fuel at the pump using the emergency shut-off switch and notify the station attendant so that all pumps can be shut off.

Static electricity is another potential cause of fire when refuelling. This can be created by the friction of the motor running, or by sliding over the seats when entering and exiting the car. Again, the risk is small, but it is better to be safe than sorry.
In addition to the safety risks, there are other reasons to turn off your engine when refuelling. For example, some vehicles experience fuel gauge malfunctions after refuelling with the engine on. There is also a danger of driving away with the hose still attached, whether the engine is on or off, but this risk is heightened if the engine is left running as you are more likely to be in a hurry to leave.
While it may be true that the risk of fire is minimal, and that race cars are often refuelled with their engines running, it is still recommended that you turn off your engine when refuelling. This is a widely accepted safety precaution, and one that should be taken seriously.

Safety of others
Safety is a key reason why it is recommended to turn off your engine when fuelling your car. While the risk of an incident may be small, it is worth taking steps to mitigate the chance of an accident occurring.
One of the main risks is the build-up of static electricity in your car. When your car is running, the engine can generate static electricity through the friction of the motor running. This static electricity could potentially ignite the gasoline vapors, causing a fire. While this is unlikely, it is still a possibility, and one that is easily avoided by turning off your engine.
Another risk is that of accidentally moving your car during the refueling process. This could lead to a major fuel spill, which could result in a fire. This is particularly dangerous if there are other people nearby, as they could be caught in the fire or harmed by the spill itself. Turning off your engine, and ideally disabling any sources of ignition, minimizes this risk.
In addition, it is important to be vigilant when pumping gas. This includes not using a cell phone, as it could cause an electrical spark, and not smoking, as this increases the risk of a fire. It is also essential to avoid overfilling your gas tank and to be careful not to get gasoline on your skin or eyes.
By taking these precautions and turning off your engine when fuelling your car, you can help ensure the safety of yourself and others around you.

Children interfering
It is important to turn off your car when fuelling to prevent children from interfering and potentially causing accidents. While it may seem like a convenient option to keep the engine running, especially during cold or hot weather, it is a safety hazard and is against the law in some places.
One of the main reasons to turn off your car when fuelling is to prevent static-electricity-related incidents, which, although unusual, can occur. The static electricity generated when sliding over seats can be transferred to the metal fuel nozzle, resulting in a spark that could ignite gasoline vapors and cause an explosion or fire. This risk is heightened when children are present, as they may inadvertently engage the drive gear, causing the car to move with the fuelling nozzle still in the tank. This could lead to a lethal accident, such as a slip, fall, or combustion.
Additionally, leaving the car running during fuelling can enhance the chance of driving away with the hosepipe still attached, creating a dangerous situation for both the driver and those around them. Furthermore, children may be at risk of carbon monoxide poisoning if cars are left running, especially in enclosed spaces like garages. This has unfortunately led to several tragic deaths, emphasizing the importance of turning off vehicles when not in use.
To ensure the safety of children and bystanders, it is crucial to follow safety protocols at gas stations. While it may be tempting to keep the engine running for comfort or convenience, the potential risks far outweigh the benefits. By turning off the engine and being vigilant about safety measures, we can minimize the chances of accidents and keep everyone safe.
It is worth noting that some people argue against the static electricity risk, stating that engines are running frequently as cars enter and exit the gas station. However, the focus should be on minimizing all potential risks, especially those involving children, who may not fully understand the dangers associated with fuelling a vehicle. Proper driver education and awareness of safety protocols are essential to creating a safe environment for everyone at gas stations.

Phone chargers
It is recommended that you turn off your car engine when fuelling to prevent static-electricity-related incidents, although these are unusual. It is also possible that power sources for phone chargers can be potential accident igniters of a fuel fire. In addition, the engine should be turned off when fuelling as the attendant may need to open the bonnet to check the oil, and it is dangerous to do this with a running engine.
To prevent this, some car manufacturers have designed their cars so that the cigarette lighter socket is only active when the key is in the accessory or run positions. This prevents the phone charger from draining the battery when the car is turned off.
Additionally, USB charging is regulated by the device itself, and the charging brick has no way of knowing the battery's voltage or how much it is supposed to be. This means that when a phone is plugged into a charger, it is already doing its own battery management. As a result, the phone may continue to draw power even after it has been fully charged, leading to potential battery damage.
To mitigate this issue, individuals can purchase a smart wall plug that can be used in conjunction with IFTTT (If This Then That) to automatically turn off the power when the phone reaches a certain battery percentage. This can help to improve battery health and prevent overcharging.
