How do I know which oil to use?

I just bought an Audi A8 and I'm not sure which type of oil to use for the best performance and longevity. Can someone help me out?

For top-notch performance and engine protection, always refer to your owner's manual for the recommended oil type and viscosity. It's usually best to stick with the manufacturer's recommendation.

If you're looking for optimal fuel efficiency and lower maintenance costs, consider using synthetic oil in your Audi A8. It may cost a bit more, but it's worth it in the long run.

One thing to keep in mind is the climate you'll be driving in. If it's extremely hot or cold, you may want to use a different oil viscosity to ensure proper lubrication and protection for your engine.
