Why is my Vauxhall Grandland engine making a loud knocking noise?

I have noticed that my Vauxhall Grandland engine is making a loud knocking noise while I am driving. It seems to get worse when I accelerate. What could be causing this issue?

It is likely that your engine is experiencing a misfire due to a lack of proper lubrication. This can be caused by using the wrong type of oil or not changing it regularly.

Another possible cause could be worn engine bearings or piston rings. These can become damaged over time and may need to be replaced.

It is also important to check your spark plugs and ignition system. If they are not functioning properly, it could be causing the knocking sound in your engine.
