* The year of your Volkswagen Cabrio: Different models and years may require different oil types.
* The engine size: The engine size influences the type of oil needed.
* The specific engine code: You can find this on the engine itself or in your vehicle's documentation.
Once I have this information, I can tell you the correct oil type and viscosity for your Volkswagen Cabrio.
In the meantime, it's always best to consult your owner's manual for specific recommendations on oil type and viscosity.
