Cars should be turned off during refueling. The following are the hazards of not turning off the engine and precautions for refueling: Hazards of not turning off the engine: When refueling at a gas station, if the vehicle is not turned off, even though the car body is not moving, the engine is still running at high speed. A running engine inevitably involves electric current flow, and if a short circuit or leakage occurs in the circuit at this time, it can be extremely dangerous. Precautions for refueling: Before refueling, the vehicle must slowly enter the gas station, and after refueling, it must also slowly exit the gas station; during refueling, the vehicle must be turned off before refueling; during the refueling process, if the gas station staff have not turned off the fuel nozzle, the car must absolutely not be started.

I always believe the engine must be turned off when refueling. It's very dangerous to refuel with the engine running, as gasoline vapors can easily be ignited by the engine's heat source or sparks, potentially causing explosions or fires. I once experienced a close call at a gas station when a nearby car didn't turn off its engine. Since then, I've made it a habit to always turn off the engine and park before opening the fuel cap. This practice also saves a small amount of fuel and reduces unnecessary emissions. Remember, safety comes first—it's a fundamental rule. Gas stations usually have warning signs about this. Turning off the engine takes just a few seconds and is no trouble at all, but it protects both yourself and others. In the long run, regularly checking your vehicle's condition during refueling can help prevent other potential issues.

As a car owner, I understand the necessity of turning off the engine while refueling because the running engine may generate static electricity or sparks, and gasoline is highly flammable, making the combination very risky. There are national safety regulations requiring the engine to be turned off, and I also believe this is responsible behavior. Turning off the engine can also make the vehicle system more stable, and the refueling speed may be slightly faster. From a convenience perspective, some people think keeping the engine running is helpful for air conditioning operation, but for safety, a brief wait is worthwhile. I recommend installing a remote start system to assist. After developing the habit of turning off the engine, it also allows for checking tires and the fuel gauge, killing multiple birds with one stone. The operation is simple and worth promoting.

I always turn off the engine when refueling—it's simple and safe. Refueling with the engine running can cause issues, like the risk of accidents from fuel vapor encountering heat. I once heard a neighbor say their engine overheated and triggered an alarm because they didn't turn it off while refueling. After shutting off the engine, I also make it a habit to lock the doors to prevent theft and take the opportunity to clean any dirt off the windows. The whole process is quick and hassle-free—safety is no small matter.

I advocate turning off the engine when refueling, primarily for environmental protection and resource conservation. Engine idling wastes fuel and increases emissions, which is harmful to air pollution. Turning off the engine can reduce carbon footprint, albeit slightly, but every little bit adds up. It also offers significant safety advantages by reducing the risk of combustion. I usually prioritize green living and recommend everyone develop this habit, complying with gas station regulations. It also provides an opportunity to breathe fresh air and take a short break.

Turning off the engine while refueling has been my practice since I started driving. Some argue that keeping the engine running is more convenient, such as maintaining cabin temperature in extreme cold or heat, but it poses greater safety risks. Turning off the engine prevents accidental sparks from causing fires—I've read related accident reports. I recommend new drivers adopt this habit early; the process simply involves shutting off the engine, engaging the handbrake, and then opening the fuel cap. This routine protects the vehicle's systems, prevents short-circuit issues, and extends engine lifespan.
