What is the best oil type for my Vauxhall Astra?

I have a Vauxhall Astra with a 1.4L engine and I'm not sure what type of oil to use. Can you recommend a specific type and brand that will keep my engine running smoothly? Thank you.

I recommend using a synthetic oil with a viscosity of 5W-30 for your Vauxhall Astra. This will provide excellent protection for your engine and is recommended by Vauxhall themselves.

I would suggest using a high-mileage oil, such as 10W-40, for your Vauxhall Astra. It is formulated for older engines and will keep your engine running smoothly for longer.

If you want to stick with a conventional oil, I would recommend using a 5W-40. It provides good protection and is more affordable than synthetic oil.
