New owner B7 RS4 phantom black. Can anyone clarify the confusion over the specified oil required the B7 RS4 ? There is an overwhelming amount of info. on VW specs, castrol, fuchs, Agip etc.... Should you follow the direction of the audi dealership or opt for a more premium oil. I will be changing my oil every 10000km or 5000km depending on how heavy I drive the car ? Feedback and information would be great Thanks Molar in the mouth.
