Again I, yesterday I noticed by chance that my oil level was already about 1 mm under the hatched area at the track bar. Since the evening was at 19:00 clock and I had to drive a decent distance, I wanted to buy oil at ARAL at the tank. The workshop filled up with me ARAL 5W40 Hitronic, but in the tank there was only 5W30, 0W40, 10W40 and 15W40. Since the Tnake also has a workshop and the Guru was standing yesterday by chance behind the counter, I asked him once. He s agte, the 5W40 is no longer available, the oW40 is the successor and unthinkable mixable with the 5W40. What do you think? Thank you and greeting Markus
