Ok. So, I've recently bought a 2013 Audi A4 2.0T Quattro.
The car was mainly driven in the city, on short distances.

When I got it, on longer extra-urban trips, the oil consumption averaged 800-1000 ml per 1000 km.
Ironically, I had the same(-ish) engine before in a GTI, and never topped the oil. Naturally, I got a bit frustrated.

This may not work for everyone, but thought I may share this solution since most people are complaining about the oil consumption but a very few share their fixes (which not include changing the piston rings).

WHAT I DID:
was pretty simple.
1. LIQUI MOLY ENGINE FLUSH with the old oil (5w30). Left the car running for about 15 min.
2. Drained the oil - added a cheap oil to clean the engine. Left it running for 15 mins with random accelerations.
3. Added thicker MOTUL X-Cess 5w40 oil.
4. Added LIQUI MOLY CERATEC to the fresh oil.
5. Try getting an engine decarb* - didn't do this yet, but should help.

With this, I got the oil consumption down to 250-300 ml per 1000 km. Which can be considered "decent", considering Audi's 1.5L/1000km is "normal".

Hope this helps somebody!
Cheers

Drained the cheap oil before that, of course...

Oil consumption isn't fixed to me until my car can go 5000 miles without that ****ty light coming up asking for a quart.

That's great to hear. I'm a little over 100K miles on my 2013 A5 2.0TFSI, so I think I'm going to try the Liqui Moly Engine Flush at some point. The car didn't burnt a drop of oil until recently when I switched to E85 and Liqui Moly Molygen at the same time. I'm not sure if it's the oil or the E85, so I'm switching back to Mobil 1 0W-40 Euro to see if it's the E85.

If anyone has a flex fuel version, with the metal intake manifold, I highly recommend E85. The car is super smooth and has a lot more power. E85 is also supposed to clean the insides as well. If I ever get a scope, I'll take a picture and share here.
