0-30 german castrol (its actually a 0-38)
my 2002 states 0-30 in the manual not sure what year they changed to the 5-40.
no oil burn i change it every 10k-15kms.
Motul xCess
great thread, I have also been thinking about what oil to put in my engine that is on its way. I was going to use 5W/40 Shell full synthetic
If cost was not a factor, what would be the best engine oil for our car
Amsoil European Car Formula, Motual 300V, Motual 8100, would be some of the few that are said to be the best.
A good oil will keep this at bay.
oil wise the Motual 300V, Motual 8100 are good ways to go. They have a strong mix
I like
Castrol GTX Magnatec 5/40 works great and its not as expensive as other choices
I would seriously recommend registering at www.bobistheoilguy.com and creating an oil recommendation thread. Give them as many details as you can and you will get some great advice. Let us know what they say 
there is a thread on AZ that gives all the information you want to know about oil. But I was trying to avoid all the AZ links from here to there. Would I be breaking any copyright laws or anything if I just copy and paste what information I want from there over here?
Also, something to keep in mind… There are 5 other fluids that need to be serviced as well. I think people focus too much on oil, and forget to change the other fluids which are equally if not more important, so could we get some information on those fluids as well? or should we start a new thread for each specific fluid?
Will do, I will let you know the out come
EDIT
Created thread, for those who would like to keep updated below is the link.

I will post the advice here as well
I’ll definitely include some info on diff, trans, and brake fluid. I think engine coolant and power steering fluid are pretty straight forward so I’ll skip those unless someone else wants to contribute. I might end up creating a new more organized thread once all the info is gathered. I’m OCD about this kind of stuff.
Perhaps it would nice to be able to add a post to the FAQ thread or have some posts stickied.
Quicky:
5w-30 synth or 5w-40 synth? What’s better in cold/hot climates?
5-40
It depends on what oil. I ran 5w-40 on my A4 here in Chicago and it was fine. Chnaces are 5w-30 is too thin.
I love Motul 8100 x-cess 5w-40 and I recommend it every chance I get
Next choice would be Mobil 1 0w-40 since it’s good and you can get it cheap and OTC
Then I guess good 'ol German Castrol 0w-30
Is there any noticable difference? I just bought some and have yet to switch over from the OEM.
So I did a little research and it seems you may use certain 5w-30 oils as long as it meets the VW 502.00 standard. I went ahead and bought the same Castrol 5w-40 my dealer uses (@Rusnak Audi, Westlake).
No matter what just make sure it meets or exceeds VW 502.00 standard. Thanks for the tips and advice guys.
When I run out of my current batch of Amsoil I’ll check out a round of Red Line 5w-40. I’ll provide used oil analysis report when it’s done. It would be really cool if one of you guys using the Castrol would get a UOA and post the results here.
Total/Elf Quarts Ineo MC3 5W30
It would be VERY cool to see UOA comparing Mobil1, Castrol, Red Line…oil threads tend to be anecdote-driven…
Yeep, same here. Came from LubroMoly, but never even thought about looking back. Xcess 8100 5W-30 and I’ve very happy.
bunch of dparm mothafuckahs up in here
Im a castrol whore so Ill do this on my next oil change. We should all use the same company and then see the results. This way we know the same company uses the same starndard tests.
