FWIW, I broke my 2.0T in meticulously and it doesn't seem to consume any oil so far. I've only got ~12,700 miles, and I change the oil every 5k. Perhaps if I followed the 10k intervals suggested by Audi then consumption would become an issue.

I broke my engine in properly too and I go through a quart every 4k miles or so.




Cheers!

Well the car is on a trip via flat bed to the dealership. In response to how the car was broken in, the answer is I don't know. I bought it slightly used with 8300 miles. I will tell you that I'm taking it to a different dealership this time. They advised me that Audi has issued a tech bulletin on the "Pressure Regulating Valve". Apparently they can stick in an open position and cause oil consumption. I'm not sure why the first dealership didn't tell me about that. Nevertheless, I will follow up with more info after the car is back home.

I've also had aSaab 900 turbo and 9000 turbo. No problems with oil consumption ever.

I was told by many BMW and Audi owners, that I am crazy for giving Audi and or Audi mechanic specialists more of my money for the every 5,000 mile oil change, instead of just waiting the 10,000 miles like it says in the manual. what do you all think?

1. Turbochargers put much more stress and heat into the oil. Remember the oil is lubricating a very hot device spinning at 100,000 rpm or more. I wouldn't be surprised to start hearing owners of the new turbo'd BMW's changing their oil more frequently.
2. Why not just do the oil changes yourself? It is pretty simple to do, you avoid the aggravation of taking it into the dealer, and your spare time is probably cheaper then thedealer's labor rate.

I bet that you'd be fine changing the oil every 10k miles. However, with all of the mods on my engine and the way I drive, I feel it is good to change mine every 5k miles. But, I do the mid change myself for around $40. Very simple on these cars.



Cheers!

With a top-quality full synthetic oil (I personally use Mobil1 and more recently Amsoil), there is no reason to change it earlier than the 10k period. I've read extensive articles on this, and the consensus/testing is overwhelming (I'm sure an internet search will give you plenty of reading material). Dino oil is a completely different matter, as is semi-synthetic, but not allowed in the A3 anyway (full synthetic only).

The fact that is the recommendation from the manufacturer is an even more overwhelming confirmation. They have zero incentive to extend milage between oil changes if it wasn't well within full synthetic's protective capability.

I'm sure if you stick with the VW/Audi OEM syntethic oil, Mobil 1, or Amsoil, you will have no problems. I'm not discounting that other synthetic oil brands aren't also good, only that those are the two brands I've had good personal experience with. I switched to Amsoil in my old autoX car and in my 2003 V-8 Explorer that I use to tow our 5800lb travel trailer camping (also put full-synthetic ATF in the tranny, but that's another story).

In short, yes, I think changing at 5k is definately not necessary. In any case, a google search should give you hours of reading/research to draw your own conclusions if you want to look into it further.

After 5,000 miles, send your oil out for analysis (and pay extra for the TBN calculation). The data you get back will allow you to gauge how your driving in your car is affecting your oil and give you the data you need to figure out whether you're pissing money away every 5,000 miles or whether the early changes are necessary. Anything else you hear, be it from a friend, folks on the internet, an Audi mechanic or even your Owner's Manual is simply speculation.

Welp, I'm officially in the club. Just added some oil today. It's consumed 1/3 of a quart in 3,7xx miles, I'm not worried about it though. I have been working the turbo extra hard for the past few months (cold air = zoooooom!)

On top of that, my brakes just started squealing today too, but to be fair I was riding them hard all day (I suppose it's not such a good thing when I get out of the car and I can smell the brakes, huh?).

PLUS, I just had to replace a Pirelli P6 yesterday due to a nail. It really kind of pissed me off to have to buy a new tire at 13,700 miles when I was planning on replacing them by 22k anyways. [:@]

What amsoil are you using and is it VW 502 spec certified?

This thread (and the similar ones on other audi forums) really worry me
