New Delhi: Whenever we go to a petrol pump to fill petrol or diesel in our vehicles, we often prefer to fill the tank to the full. While filling fuel, the machine stops automatically, which is called auto-cut. However, sometimes people try to fill a little more petrol or diesel even after this, so that the tank is completely filled.

This raises the question: is it right to fill fuel after auto-cut? Can it damage the vehicle's tank or other parts? If you have been doing this all along, then learn these important things about filling fuel.

What is auto-cut?

The fuel nozzle at a petrol pump has a special system that stops the fuel supply when the tank reaches a certain level. This is called auto-cut. This system helps prevent overfilling the tank. Auto-cut means that the nozzle should stop filling with fuel. After this, repeatedly pressing the trigger to try to fill fuel is not a good practice.

Why should fuel not be refilled after auto-cut?

Refueling after an auto-cut can reduce the amount of space needed for the petrol or diesel to expand. It's also important to keep a small amount of space in the vehicle alongside the fuel, as fuel can expand as temperatures rise. Overfilling the tank can result in spillage or damage to the vehicle's fuel system. Therefore, refueling after an auto-cut should be avoided.

Does this harm the car's engine?

It's not always true that refueling after the auto-cut will damage the engine. However, repeatedly overfilling the tank can affect other parts of the vehicle. Especially petrol-powered vehicles have a dedicated system to handle fuel vapors. Overfilling the tank can cause liquid fuel to enter the tank, which can damage certain parts of the system. This can cause problems and increase repair costs.

What things should be kept in mind while filling petrol?

When refueling, ensure the nozzle is properly positioned and ask the service personnel to stop refueling as soon as the auto-cut occurs. There's no need to repeatedly press the trigger just to fill the tank completely. Also, keep the vehicle's engine off while refueling.

Should the tank always be kept full?

There's nothing inherently wrong with filling your tank. You can fill it up when you refuel with petrol or diesel, but don't try to top up the fuel after the auto-cut. If you drive daily or are traveling long distances, it's okay to fill up as needed. Just be careful not to overfill the tank.

Check the meter after filling fuel

After filling up at a petrol pump, don't proceed just by looking at the bill. Be sure to compare the quantity shown on the machine with the quantity on the bill. If you suspect that the fuel has been underfilled or there's something wrong with the meter reading, talk to the employee there. Also, check to see if the meter is at zero before refueling. This will ensure you've started reading correctly.

Remember this when refueling

Auto-cut is an important signal when refueling your vehicle. Avoid refueling afterward. This reduces the risk of fuel spills and helps protect your vehicle's fuel system. Next time you're at a petrol pump, don't ignore auto-cut in your rush to fill your tank.
