What causes the Astra's engine to shake?

I've noticed that my Vauxhall Astra's engine seems to be vibrating more than usual. What could be causing this and how can I fix it?

The most common cause of engine shaking in an Astra is a problem with the spark plugs. It's important to regularly check and change them to prevent this issue.

Another possible cause is an issue with the engine mounts. If they are worn or damaged, they can cause the engine to vibrate. Get them checked and replaced if necessary.

Low engine oil levels or dirty oil can also lead to engine shaking. Make sure to check and change your oil regularly to prevent this.
