What is the ideal oil type for a Vauxhall Mokka?

I recently bought a used Vauxhall Mokka and am unsure what type of oil to use. I want to make sure I am using the best option for my car. Can you provide any recommendations?

The Vauxhall Mokka manual states that the recommended oil type is GM DEXOS2 5W-30. This is a synthetic blend oil that provides optimal engine protection and performance.

I've been using Castrol EDGE 5W-30 in my Vauxhall Mokka and have had great results. It is a fully synthetic oil that offers excellent engine protection and fuel efficiency.

Personally, I prefer using Mobil 1 5W-30 in my Vauxhall Mokka. It is a premium fully synthetic oil that provides superior protection and performance.
