Refuelling is a routine part of driving, but one question still concerns many motorists: Is it safe to refuel while the engine is running? Despite how common the misconception is, leaving the engine on at a fuel station is unsafe and goes against standard safety rules followed across the UAE. Understanding why this rule exists helps ensure safer refuelling every time.
Why You Should Never Refuel With the Engine Running
Fuel vapours, heat and electrical components can create unnecessary risks, which is why petrol stations always require drivers to switch off their vehicles before refuelling.
Many drivers fall for the common car fuel myth that it’s safe to refuel with the engine on — a misconception that can put you at serious risk. Here are some common reasons why refuelling with the engine running is considered unsafe and strictly prohibited:
Fuel Vapours Can Ignite
Petrol gives off highly flammable vapours. When a car’s engine is running, components like the alternator, ignition or even a hot exhaust can potentially create sparks.
Even a tiny spark can cause fuel vapours to ignite. Extra caution is needed when refuelling a car in hot weather, as higher temperatures make fuel vapours more volatile.
Static Electricity Risk
Static electricity can build up when you exit and re-enter your car during refuelling. When the engine is running, fuel pumps and electrical systems increase the chances of static discharge near vapours.
Car Safety Systems Can Malfunction
Modern vehicles feature automatic stop/start systems, fuel pumps, electrical relays and sensors that can activate unexpectedly if the engine is left on. Any sudden electrical activity around fuel vapours is unsafe.
It Violates Petrol Station Safety Regulations
All petrol stations in the UAE (Adnoc, ENOC, EPPCO, Emarat) clearly instruct drivers to turn off their engine before refuelling. Not following these regulations can result in an AED 10,000 fine and three months’ jail in some cases.
Dos and Don’ts While Refuelling in the UAE
Follow these essential refuelling dos and don’ts to ensure your safety and comply with the regulations of UAE petrol stations.
Dos When Refuelling
Here are some essential dos to follow every time you fuel your car:
- Turn off the car completely: Shut down your car completely, including accessories like the radio and AC, before refuelling to eliminate ignition risks.
- Keep kids inside: Ensure children remain safely buckled in the vehicle, away from fuel pumps and vapours.
- Stay near the pump: Never leave the nozzle unattended while refuelling to prevent spills and accidents.
- Use the nozzle latch correctly: Engage the dispenser’s automatic latch if available, but never force it, as this can damage the pump or cause leaks.
- Check the fuel cap: After filling, make sure the cap is closed tightly to prevent fuel evaporation and leaks.
- Discharge static electricity: If you re-enter the car during refuelling, touch a metal part of the car away from the filler neck before handling the nozzle to discharge any static electricity safely.
- Use the correct fuel type: Confirm you’re using the right fuel type, suitable for your vehicle, to avoid engine damage.
- Follow Staff Instructions: Attendants at full-service stations (like Adnoc On-the-Go) follow strict safety protocols. It is advisable to cooperate with them.
Don’ts When Refuelling
Here’s what to avoid during refuelling to stay safe:
- Don’t run the engine: Even if you’re only stopping briefly, turning off the engine ensures maximum safety.
- Don’t re-enter your car: Moving in and out of the car during refuelling can generate static electricity, so avoid this habit.
- Don’t use electronic devices: Mobile phones and other electronics should be kept away as a precaution against sparks.
- Don’t overfill the tank: Avoid topping off fuel after the nozzle clicks off to prevent spillage and vapours.
- Don’t smoke or use phones: Avoid smoking or using mobile phones during refuelling to reduce ignition risks caused by sparks.
What If You’re in an Emergency?
Even in emergencies, such as a medical situation requiring a quick departure, the safest option is always to turn off your engine before refuelling. Minimising exposure to fuel vapours and following proper safety protocols is crucial, regardless of the circumstances.
While car refuelling tips can help you refuel efficiently, leaving the engine running is never fully safe. In fact, UAE fuel stations strictly require drivers to switch off their vehicles before pumping fuel.
FAQs
Why do petrol stations require you to switch off the engine?
Turning off the engine removes heat and sparks from electrical systems, ensuring fuel vapours don’t catch fire.
What are the dangers of refuelling with the engine on?
Leaving the engine running can lead to fire, static electricity discharge, fuel spills and even the malfunction of car electronics.
Are hybrid or electric cars safer when refuelling?
Hybrid vehicles still have combustion engines that must be off during refuelling. Fully electric cars don’t use petrol, so this risk does not apply.
What should you do if a fire starts at a petrol station?
Move away immediately, alert station staff, use a fire extinguisher only if trained and call emergency services. Safety should always come first.
What is the fuel price in the UAE?
Petrol prices fluctuate every month. As for December 2025, the petrol price in the UAE is as follows:
- Super 98: AED 2.70 per litre
- Special 95: AED 2.58 per litre
- E-Plus 91: AED 2.51 per litre
- Diesel: AED 2.85 per litre
Refuelling your vehicle with the engine running is unsafe and should be avoided at all costs. To comply with UAE safety regulations and keep yourself and others safe, always turn off your engine while refuelling, follow the dos and don’ts and stay alert at the pump.
Safety at the pump is a simple but essential part of responsible vehicle ownership. Whether you’re driving a brand-new car or a used car for sale in the UAE, adopting these habits helps protect your vehicle, yourself and everyone around.
