Default Follow-up to my oil change question..Why are most people using 0-40 M1 instead of 10-40 M1

I am in the southeast (N.C) and was planning on picking some Mobil 1 tomorrow.
Just want to be sure about the weight before I pick it up.
.
Also, I was told that a 5 Qrt jug is NOT enough for the A6 and to get a case of 1 Qrt bottles. can anyone confirm this?
Thank you all

Default 5 quarts is not enough, Use 5-30, 5-40, 5 -50 or 0-30, 0-40

If you had turbos I would say use only 0-30 or 0-40. Since you do not have turbos the 5-30, 5-40 or 5-50 should be fine. Synthetic oil is much better than conventional so the Mobil one is a great choice.

Default Because Audi/VW recommends a 5W-40 or 0W-40 oil

Audi/VW has a published oil quality standards sheet numbered either VW 502 00 or VW 505 01. This sheet lists all of the approved oils and their weights. Look down the list and you'll see that 10W-40 is not on the list.

Mobil 1 0W-40 synthetic is often used because it is widely available.

I bought 8 quarts for my 2.7T and have one left to top up. So 7 quarts with filter.

Castrol Syntec 5-40 is not available in N. Cal so I use 5-30 also recommemned by dealer service.

Default 1) because 10W40 is not approved by VW/Audi 2) rad your manual - depends on motor

Most take between 5.5 and 6.5 quarts, so generally a jug is insufficient. 4.2 takles 8 quarts.

I dont believe M1 maks 10W40 by the way.

I used 5W30 in my S4 2000 with very good results. Turbos happy for 80k miles when I sold it. That's probably a good choice too.
