Must the Engine Be Turned Off When Refueling?

[Alves]

It is mandatory to turn off the engine when refueling a car. Below is a detailed explanation of the reasons why the engine must be turned off during refueling: 1. Gasoline is an electrolyte: Choosing to refuel while the car is still running may cause leakage in some operational car instruments, leading to short circuits or circuit failures. 2. Gasoline concentration in the air: When the vehicle is running without being turned off, the instruments inside generate a significant amount of heat, accelerating the volatilization of gasoline. Refueling while the engine is still on increases the concentration of gasoline vapor around the fuel tank. 3. Exhaust pipe emissions: During operation, the car's exhaust pipe continues to emit exhaust gases. On one hand, the exhaust pipe can reach very high temperatures, and on the other hand, the exhaust may carry sparks, which can easily pose safety hazards.

It is indeed necessary to turn off the engine when refueling, primarily for safety reasons. I remember a lesson from a gas station—when the engine is running, there are high temperatures and potential sparks, and gasoline vapors can easily ignite, causing a fire. Turning off the engine significantly reduces this risk. Additionally, shutting off the engine minimizes hazards from vehicle vibrations, preventing unintended movement or accidental starts. Personally, I make it a habit to turn off the engine as soon as I park, then proceed to refuel slowly, making the whole process calmer and more reassuring. After adopting this small habit, my refueling speed hasn’t been affected; in fact, it helps save a bit of fuel and reduces exhaust emissions. Overall, this is a common-sense practice to protect yourself and those around you—it’s best not to skip it out of laziness.

Turning off the engine while refueling is essential—it's not just about safety, but also environmental care. Idling the engine wastes fuel and emits air pollutants; shutting it off keeps the air cleaner and saves you some money on gas. Every time I visit a gas station and see others turn off their engines to refuel, it strikes me as a smart move. I also power down my car, using the time to check tire pressure or catch up on messages—no wasted minutes. Over time, this habit extends your car's lifespan and prevents engine overheating. Remember, this small action isn’t a hassle—it’s part of responsibility and eco-friendliness. If we all follow suit, the world will see less pollution.

It's really not recommended to refuel while the engine is running, as it can generate sparks that may ignite gasoline vapors. Turning off the engine is much safer, and the refueling process is smoother when the vehicle is stationary. A friend of mine once had a minor accident because they didn't turn off the engine, which was a profound lesson. Now, I always turn off the engine and electrical devices to prevent static electricity risks. It's advisable to wait a few seconds after stopping before refueling—making it a habit saves trouble.
