Interesting thread on BITOG about the Audi Quarterly recommended oil for Audis.
To sum it up in a few words, they recommend a minimum HTHS of 3.5cP.
The HTHS of the most recommended oils mentioned on this forum are:
M1 0W40 - 3.6
Amsoil 0W30 - 3.4
German Castrol 0W30 - 3.6
M1 0W30 - 2.9
M1 Delvac or T&SUV 5W40 - 4.1
If any one has the article, please scan it. Might make an interesting read.<ul><li><a href="http://theoildrop.server101.com/ubb/ultimatebb.php?ubb=get_topic;f=1;t=010499;p=1">BIT OG thread</a></li></ul>

I think Audi should decide whether they want to be a boutique manufacturer or a real automotive
player Worldwide(the latter being the impression I get overall). I can understand special one-offs or runs(B7 RS4) requiring exotic or special requisite oils but to require something like this in a volume-based product shows they are focusing their "engineering" in the wrong areas.
I read some of the oil reports occasionally and having had many domestic and Japanese high mileage engines in my family over the past 20 or so years these products have all performed as adverstized and with little/no compression losses. Granted these had oil changes every 3500mi but usually with the cheapest slop off the shelf for the most part.
I think Audi should send some engineering talent to Nissan, Honda, or GM to determine how to make a strong, reliable, robust engine like these manufacturers without requiring exotic oil specifications. Audi seems to make it a habbit of overengineering just for the sake of complexity and marketing. I fail to see the advantages in this when other products are virtualy the same with much less maintenance costs...

John, have you read up on this Amsoil release?
Have been looking for the GC to try but no one in my area has/carries it.
May play with this next...<ul><li><a href="http://www.amsoil.com/storefront/afl.aspx">European Amsoil Release:</a></li></ul>

Will do. Isn't the GC GIII though? ...read somehthing about modified esters recently in it.
Don't really guess it matters as long as it meets requirements and produces the desired results.

i don't understand ..
they require a higher viscosity to reduce cam & bearing wear?
this goes against my understanding of oil & viscosity. i thought thicker oil causes more cam & bearing wear because it has less flow.
