Why is my Vauxhall Corsa's engine making a knocking sound?

I noticed a knocking sound coming from my Vauxhall Corsa's engine. It seems to be getting louder and more frequent. What could be causing this and how can I fix it?

The knocking sound you hear is likely caused by engine detonation. This can be caused by a number of factors, such as low quality fuel, incorrect ignition timing, or a clogged fuel filter. It is important to address this issue as soon as possible to avoid causing damage to your engine.

One possible cause of the knocking sound could be worn out engine bearings. Over time, these bearings can wear down and cause a knocking sound. If this is the case, it is important to have them replaced by a professional mechanic.

Another common cause of engine knocking is low oil pressure. This can be caused by a leak or engine wear. Check your oil levels and if they are low, top them off and check for any leaks. If the problem persists, have a mechanic check for any engine wear.
