What are the benefits of using synthetic oil in a Vauxhall Insignia?

I recently heard about synthetic oil and was wondering if it would be beneficial to use it in my Vauxhall Insignia. Can you explain the advantages of using synthetic oil over conventional oil? Will it improve engine performance and longevity? Is it worth the extra cost?

Synthetic oil is made up of specially formulated chemical compounds that offer superior lubrication, protection, and cleaning of your vehicle's engine. It can improve engine performance, reduce wear and tear, and increase the longevity of your engine.

Synthetic oil can also withstand extreme temperatures better than conventional oil, making it ideal for high-performance engines. It also has a longer lifespan, meaning you won't have to change it as frequently.

Using synthetic oil can also improve fuel efficiency and reduce emissions, making it better for the environment.
