What are the issues with refueling without turning off the engine?

There is no significant impact, but there are safety hazards. Refueling without turning off the engine will not damage the vehicle's components. However, when the engine is running, it operates at high temperatures, and the vehicle's electrical systems remain active. If there is an electrical leakage that produces a spark, it could lead to an explosion at the gas station. Below are precautions to take when refueling: 1. Never refuel the car before turning off the engine. 2. If the staff has not turned off the fuel nozzle, the driver must not start the car, as this could easily cause a fire. 3. It is best not to refuel during thunderstorms. This is also a safety precaution to prevent lightning strikes and potential fires. Since automotive fuel is highly flammable, during refueling, flammable vapor can disperse into the surrounding air. If struck by lightning, the consequences could be disastrous.

Refueling without turning off the engine is really dangerous. Last time at the gas station, I saw a car owner refueling without shutting off the engine, and my heart was in my throat. When the engine is still running, the exhaust pipe and the area around the engine compartment are extremely hot. At this time, the gasoline vapor released during refueling can easily ignite. With so many vehicles coming and going at the gas station, if static electricity sparks or a short circuit occurs accidentally, the consequences would be unthinkable. Every time I refuel, I turn off the engine, remove the key, and get out of the car—it's a habit I've developed over many years. Although it only takes a few minutes, safety is the top priority. I strongly advise everyone not to take risks for convenience.

I think there are two major issues with refueling without turning off the engine: safety hazards and environmental concerns. Everyone understands the safety hazards. I heard that there was a fire accident caused by refueling without turning off the engine in another city recently. Then there's the environmental issue. When the vehicle is idling, it emits a large amount of exhaust fumes. Gas stations are relatively enclosed spaces, and these exhaust gases can affect air quality, which is harmful to the health of staff and people around. Every time I go to refuel, the staff emphasize the need to turn off the engine, which shows the seriousness of the problem. I suggest everyone develop the habit of turning off the engine—it's safer, more environmentally friendly, and can even save some fuel costs.

From the owner's perspective, refueling without turning off the engine can also damage the vehicle. Prolonged idling leads to incomplete combustion in the engine, which easily causes carbon buildup. Over time, this will affect power performance and fuel consumption. I once had a friend who always refueled without turning off the engine, and by 20,000 kilometers, obvious carbon buildup issues appeared. More importantly, there are safety hazards. The large amount of gasoline vapor generated during refueling can come into contact with high-temperature engine components or electrical sparks, potentially causing serious accidents. For your own safety and the health of your beloved car, always turn off the engine when refueling.

From a daily usage perspective, refueling without turning off the engine may seem convenient but is actually very dangerous. While the vehicle is running, the electrical systems are active, and during refueling, the concentration of gasoline vapors is high. A small spark could lead to serious trouble. I've noticed that formal gas stations require the engine to be turned off during refueling, and staff will intervene if not. This is not just a safety regulation but also a responsibility to others. Once, I forgot to turn off the engine while refueling and was warned by the station, which made me extra cautious now. I recommend everyone develop the habit of turning off the engine—safety is no small matter; don't risk a lot for a little.

As someone who frequently observes at gas stations, I've noticed that many minor accidents stem from refueling without turning off the engine. When a vehicle is running, there are numerous hazardous factors near the fuel tank: hot exhaust pipes, operating generators, and electrical systems prone to sparking. Opening the fuel tank to refuel under these conditions causes an immediate accumulation of gasoline vapors around the nozzle. I've seen test data indicating that the probability of a fire in this state is dozens of times higher than when the engine is off. I recommend drivers double-check their vehicle's status before refueling—turn off the engine before exiting the car. This entire process only takes an extra ten seconds or so but significantly enhances safety.
