What is the correct oil viscosity for a Vauxhall Vivaro 1.6 CDTI engine?

I recently purchased a Vauxhall Vivaro with a 1.6 CDTI engine but I am unsure about the correct oil viscosity to use. Can anyone provide some guidance?

You will need to use a 5W-30 viscosity oil for your Vauxhall Vivaro 1.6 CDTI engine. This is the recommended oil by Vauxhall for optimal performance and fuel efficiency.

I have been using a 0W-30 viscosity oil for my Vauxhall Vivaro 1.6 CDTI engine and haven't experienced any issues. Ultimately, it is important to choose an oil that meets the requirements outlined in your owner's manual.

I would highly recommend using a synthetic oil for your Vauxhall Vivaro 1.6 CDTI engine. It may cost more upfront but it will provide better protection and last longer between oil changes.
