Audi A5 Engine Oil Recommendation

What type of engine oil is recommended for an Audi A5? Is it necessary to use fully synthetic oil? What about the oil viscosity? Any specific brands that are recommended?

For your Audi A5, it is highly recommended to use fully synthetic engine oil. This oil is specially designed to meet the high-performance demands of your vehicle's engine. As for the oil viscosity, check your owner's manual for the recommended range. Generally, 0W-20, 5W-30, and 5W-40 are common options for Audi A5s. As for specific brands, it is best to use brands that are approved by Audi, such as Mobil 1, Castrol, or Shell.

I would recommend using fully synthetic oil for your Audi A5. It may be a bit more expensive, but it offers better protection for your engine and can handle higher temperatures. As for the oil viscosity, you can refer to your owner's manual for the recommended range. In terms of brands, I have had good experiences with Castrol and Mobil 1.
