What is the recommended oil for a Vauxhall Insignia?

I just bought a Vauxhall Insignia and I am not sure what type of oil to use. Can someone provide a recommendation based on personal experience?

The recommended oil for a Vauxhall Insignia is a fully synthetic oil with a viscosity grade of 5W-30.

I have been using Castrol EDGE 5W-30 in my Vauxhall Insignia and it has been working well for me.

I suggest using Mobil 1 5W-30 oil for maximum engine protection and improved fuel economy.
