Or for another $1/qt up grade to RL.
My interest in trying it is to find an oil that does not varnish my VW engine in 4k miles like many synthetics have. If it lasts longer before varnishing, that lowers the oil cost per mile.
Honestly, if VW engines (I am assuming 2.0T?) are as similar to BMW engines as I typically imagine, I would think either Redline or Royal Purple would work well, but due to the Turbo I would go with Redline. My S/C 328 likes Redline a bit better: slightly quicker boost build-up (noticeable on a Twin-Screw Lysholm blower), lower S/C temps, lower wear.
IMO, GrpV oils are the way-to-go for any FI engine. Regarding varnish buildup: Redline and Royal Purple cleaned all 3 of my Bimmers, and did so very well, and since the cars have used them exclusively there has been ZERO varnish/sludge return. (I don't drive my cars "easy", either, and the 328 gets many track days in every year).
Hope that helps a bit

PS: I have been hearing more and more about using either RL/RP with LM MSo2 additive OR Lubro-/Liqui-Moly oils with a dash of Redline Break-In Oil, and this is coming from a bunch of friends who are track-rats running everything from E30 M3's to a Turbo Miata, a few S2000's and a 2009(?) Corvette Z06... They all seem to like either combo, but I have yet to try them.
