IIRC royal purple doesn't meet the API / warranty requirements . My Navigator (J.stewart) dug up a bunch of information after he bought his WRX. he ended up going with AMSOIL he became a dealer so he can get good prices on it.

I was buying it for my STI but i go through so much oil it seemed wasteful. (It did Reduce my consumption noticeable) But now i just dump in straight 30 Weight and hope it still cold starts when its 30F out

I was running Redline in my rally car (won a bunch of 5-30 oil in Rally crosses) and i actually seemed to get 1 mpg over the "napa oil"
