GC 0w-30 is perfect for that engine for virtually any street use. Redline 10W-30 is also excellent, and even better if tracking, provided that short trips are not excessive.
Any high quality 10W-30 synthetic is also good. You won't need anything heavier than that where you are. Save the 40 weights for the pre-'99 white blocks. I wasn't a huge fan of M1 0w-40 in these, but it's been a few years and I don't know what the formula is anymore. None of them should hurt you, however.
The most important thing with any white block turbo is that it be FULL SYNTHETIC. The VCNA recommendation does not require that, and dealers may (and have) pump(ed) bulk conventional 5w-30 into them. At the 7,500 warranty interval, that can spell sludge. That's why you may see so many dirty white blocks here in the US.
AutoRX it if it's dirty; avoid the solvent cleaners on the turbo.
Unless you have the benefits of UOAs, baseline the change interval at 5k; 7,500 can be too long on a turbo with the wrong oil. All else equal, the interval is harder on a T5, harder still on an R. I recall even M1 0w-40 getting chewed up pretty quickly on a hard driven R from past UOAs posted here.
FWIW, I run GC in my R, and had run Redline previously for more spirited driving. No problems and spotless inside.
A Mann or Mahle filter is fine in these. The OEM is a Mahle.
