I drove only 4000 km in a year. Volkswagen advises that I change the oil in 15,000 km kilometers or 1 year. In this case, what do I need to do, because I have driven only 5000 km.
@Shog9 slight edit: "Yes, it's mandatory.. The oil police ..." Those guys are super judgy, too. You don't want to be judged by them. You'll feel like a bad person all day. ;-)
