The long drain specs for the Volkswagen in Europe are VW 503.00 for gas engines going 30,000 KM between drains. VW 506.00 for diesel engines going 50,000 KM between drains.
The North American sold, German blended Castrol is rated for VW specs 502.00, 505.00, 503.01 so this oil is not the extended drain interval oil specified in Europe for Volkswagen. This oil is a fuel conserving oil.
The Castrol does meet BMW long life-01 spec which will go up to 15,000 miles based on the oil life monitor of the vehicle. It meets Mercedes Benz MB 229.1, MB 229.3 (gas engine specs) which is also good for 15,000 miles based on the vehicles oil life monitor. The oil meets Porsche approval also but I have no idea what their drain interval is based on.
