Why is my Vauxhall Zafira's engine making a knocking noise?

I recently noticed that my Vauxhall Zafira Life's engine is making a knocking noise whenever I accelerate. It sounds like metal hitting against metal. What could be causing this and how can I fix it?

It is likely that your engine is experiencing abnormal combustion, also known as engine knock. This can be caused by a variety of factors such as low fuel quality, incorrect ignition timing, or carbon buildup in the cylinders. It is best to take your car to a professional mechanic to diagnose and fix the issue.

The knocking noise may also be a sign of a worn out or damaged engine mount. This can cause the engine to vibrate and make loud noises. I recommend getting your car inspected by a mechanic to determine if the engine mount needs to be replaced.

Sometimes, the knocking noise can be due to a lack of lubrication in the engine. This can be caused by dirty or low engine oil. Make sure to check your oil levels regularly and get an oil change if needed.
