What is the ideal oil type for a Vauxhall Insignia?

I am curious about the type of oil that would work best for my Vauxhall Insignia. I want to ensure that I am using the right kind of oil for optimal performance and longevity of my vehicle.

It is recommended to use a fully synthetic 5w-30 motor oil for your Vauxhall Insignia.

I have found that using a 5w-40 synthetic blend is more cost-effective and still provides good performance for my Vauxhall Insignia.

Based on personal experience, I suggest using a 0w-20 full synthetic oil for the smoothest engine performance.
