Which oil to use?
Just got an 05 A8 with about 70K on it and about to change oil and filter. I read the oil change info sticky on this site. But still unclear as to what weight oil to use. Planning on going with Mobil 1 but do I use0w30, 0w40,or 5w40? I live in new England Thanks

whats the difference between the 5w40 and 0w30? When I called the dealer, they told me 5w40, but in the manual it states 0w30. What did they change it or something? I just dont want to use the wrong type of oil and shorten the life of my motor. Thanks

5w40 is a hair thicker than 0w30 and is approved by Audi...and acceptable. In colder climate, I would opt for the 0w30 since it would tend to remain thicker from the cold.
5w40 will not hurt anything. Sometimes just a matter of opinion and general climate. In older motors, some use thicker than recommended oil to gain a little more oil pressure and some believe less likely to leak(?)
