Hello, I have to bring my R8 V10 R Tronic to the Audi center before June. There an oil change should take place. Since I will bring my own oil, I would have to know how much liters of oil I should get in advance. Furthermore, which oil. I have found these two in the net here: 5W30 or 10W60 What do you think, which of the two should I prefer. I leave two pictures there… Thank you in advance.
