What is the recommended engine oil for a Vauxhall Crossland?

I've recently bought a Vauxhall Crossland and i'm not sure what type of engine oil i should use. Can you provide recommendations and possible consequences if I don't use the recommended oil?

It is recommended to use a fully synthetic 5W-30 engine oil for your Vauxhall Crossland to ensure optimal performance.

Using a non-recommended engine oil may result in engine damage, reduced performance, and increase in fuel consumption. Stick to the manufacturer's recommendations for best results.
