Incorrect. Most, if not all US VW dealers us Castrol Syntec 5w40 for their gassers, turbo or not. In the TDI diesels, they use Castrol SLX 5w30.
By the way, Syntec 5w40 is pretty darn good oil. If you doubt, then study the dozens of UOA's that have been turned in by all the Audi and VW owners over the past ten years....from the 1.8 to the 2.0 Turbos. There are several that have 10K OCI's that are pretty darn good. Is 5w40 the best?????....I don't think so, but it doesn't deserve to be slammed. For goodness sake, it holds the 502 specs.
I am choosing to apply a 5k OCI on my 2.0T. The dealer is doing the free changes at the 10k interval and is using Syntec 5w40. I am doing my own changes, in between at the 5k mark and so far, I have been using GC.
Due to the Black Friday sales, I ended up with 4 cases of Mobil 1 0w40 and it will be the oil I use for a while....a least three changes (my son's Rabbit gets the other 3).
The bottom line, if you are serious about your warranty, stick with a 502 spec oil and stick with 5w40, per your manual. As long as the oil carries a 502 spec, I am comfortable using it....while on warranty.
Once out of warranty, I think I am moving to Rotella T6, 5w40.
