How to keep my Vauxhall Insignia's engine running smoothly?

I've noticed that my Vauxhall Insignia's engine has been making strange noises lately. What could be causing this and how can I make sure my engine runs smoothly?

This could be indicative of a problem with your fuel injectors. Try using some fuel injector cleaner to see if that helps.

Check your oil levels regularly and get your oil changed every 3,000-5,000 miles. This can help prevent engine problems.

If the noises are coming from your timing belt, it may need to be replaced. Consult with a mechanic to get it checked.
