I recently purchased a 2021 Audi A4 and I am wondering what is the best oil viscosity to use for optimal performance and engine longevity? Does it vary based on geography or climate?
ReplyFor the 2021 Audi A4, we recommend using 0W-20 synthetic oil for best performance and engine protection. This viscosity provides excellent protection in extreme temperatures and improves fuel efficiency.
Based on your location and climate, you may need to adjust the oil viscosity for your Audi A4. In colder climates, a thicker oil like 5W-30 may be more suitable, while hotter climates may benefit from a lighter oil like 0W-30.
