Best engine for Vauxhall Insignia

Which engine type is the most reliable and fuel efficient for a Vauxhall Insignia?

I have found the 2.0L petrol engine to be quite reliable and efficient in my Vauxhall Insignia. It has a good balance of power and fuel efficiency, making it a great all-around choice.

In my opinion, the 1.5L turbo petrol engine is the best choice for the Vauxhall Insignia. It offers a good combination of power and fuel efficiency, and has been quite reliable in my experience.

Based on my personal experience, the 1.6L diesel engine is the most reliable and fuel efficient option for a Vauxhall Insignia. It has good power and excellent fuel economy, making it a great choice for both city and highway driving.
