I have situation hesitated to ask my workshop, but it was no problem to bring the oil itself with. This is usually the thickest item on the customer service account. But is not a problem. He says that he deserves nothing anyway on oil. I drive the oil in the T5 and the Polo TDI in total. 200 000 km and have never had problems. In addition, you can afford loose in the oil price, the oil change (wg. Much short-haul) preferred times. Because I trust more than the favorable oil Longlife fairytale.
