What is the best oil to use for a Vauxhall Astra?

I recently bought a Vauxhall Astra and I'm wondering what type of oil is best to use for optimal performance and engine health? I've heard conflicting opinions and I want to make sure I'm using the right oil for my car.

You should always use the type of oil recommended by the manufacturer for your specific model and year of Vauxhall Astra. This information can be found in your car's owner's manual.

It's also important to consider the climate and weather conditions in your area. Thicker oil may be needed for hotter temperatures, while thinner oil is more suitable for colder climates.

Regularly checking and changing your oil according to your car's maintenance schedule can also greatly improve the overall performance and longevity of your Vauxhall Astra.
