Oil burning on the "new" 2.0 Turbo TSI, introduced mid 2008 is much, much reduced compared to the 2.0 FSI (
We don't really know yet if the TSI is as hard on oil as the FSI. The FSI is brutal on oil. Assuming the TSI is as hard on oil as the FSI (and that is not really a safe assumption because we simply don't have enough data yet) of those mentioned above, I would not run m1 0w40 (shear rate is 15-25% in a very short time on the FSI and flashpoint retention is poor) but I would run Biosyn 5w40 or that HDEO 15w40. I definitely would not run Pennzoil Ultra because it's HTHS is very low, 3.1 as I recall. That's even less than the 502 minimum of 3.5
Amsoil DEO, Motul 300V, Redline 5w40 (HTHS 4.6) or 10w40 (HTHS 4.7) would all be good ones to consider. Redline's volatility is 6% which is very low.
If I had to run a 502 oil, Motul x-lite ow30 or GC would be my pick.
In the 2.0FSI, so far the best performer in terms of shear, flashpoint retention, and possibly metals is Brad Penn 10w30. But there is only one UOA of that so far. Shear was 5% and flashpoint was around 400 as I recall which is staggeringly good. Redline 5w40 had the next best shear average at around 11-13% and flashpoint retention, followed by Biosyn 5w40. It is a large drop from these oils to the many 502 oils. Keep in mind that for FSI runs 99% highway, any oil does great. 502 oils do not cut it in the FSI engines and pretty much any oil (including the better than 502 oils) do not last beyond 5000 miles. We don't know yet if 502 oils are inadequate for the TSI.
In Europe where a lot of this testing is done, the cars run in a different mode and they don't have fuel dilution as bad as we do in the U.S.
The 2 problems I would keep in mind are fuel dilution and valve deposit buildup. Using a good oil can help alleviate these problems somewhat but is not a cure all. Chaning every 5k as recommended above is wise until we know that we can run longer on the TSI. Search for the 2.o FSI database, direct injection, valve buildup, pcv bypass, carbon deposits etc. etc. to find more info.
In parting, here are the valves of a 2.0FSI car that ran m1 0w40 according to the manual changed every 10k miles. I have posted on most topics re FSI, direct injection, valve buildup, etc. so feel free to browse my posts to find relevant threads (Bitog search engine is not the greatest). Also, re warranty, many use better than 502 oils that are not on the list and keep any of the following: maintenance log documenting 502 oil use, receipts for 502 oils that are returned, photos of oil change.
P.S. I would do exactly what you are saying if it were my car, except for the oil change interval. Change at 1000, then redline 5w40 or 10w40 every 5000 thereafter. Doing a UOA will tell you clearly if you can run it longer, say 7000 miles, 10,000 miles, etc. I bet the TSI will support longer oil runs. But it would not be wise IMO to go longer than the proven 5k FSI "limit" until we get some more UOAs on those engines to know if it is safe. ALL IMO and feel free to disregard all.
