For someone considering a thicker oil, you should first do a used oil analysis to determine if you need a thicker oil. Even if I had an Impreza that burned oil using 0W-20, I would switch to a 5W-20 before trying a 30 grade. 5W-20's are more stable and usually have better NOACK volatility ratings (less evaporation).

I don't see many BRZ uoa's but there are a lot of good ones on ft86club.com using 0W-20.

There is rumor that at least in some markets, some XV's have supposedly come filled with 5w20. I highly doubt it but thats what I've heard. I have my factory fill stored in clean containers, so i could send some off.
But I'm not that curious to spend money on finding out.
