Here's why:
* Engine variations: Audi A8 Quattros come with different engine types (V6, V8, W12) across model years. Each engine has different oil requirements.
* Oil specifications: The recommended oil type and viscosity will be specified in your Audi A8 Quattro's owner's manual.
* Local conditions: Factors like climate and driving conditions also play a role in choosing the right oil.
What you should do:
1. Consult your owner's manual: This will provide the most accurate and up-to-date information on the type of oil your specific Audi A8 Quattro engine requires.
2. Contact an Audi dealer or certified mechanic: They can advise you on the appropriate oil type and viscosity for your vehicle based on its model year, engine, and local conditions.
Remember, using the wrong oil can harm your engine. It's always best to follow the manufacturer's recommendations.
