Interesting thread. Not sure if I am going to follow Subie's recommendations this time around..
Currently have a 08 Tribeca with a 3.6 engine @ 45k miles. I've been burning though about 1.5qt of oil/1000 miles. Fortunately i am still under powertrain, so it looks like Subaru is going to give me a new short block. Makes me wonder if "following the manuals recommendations" - i was diligent in varying speed and keeping it under 4k revs caused my issues a few years back. After doing a lot of research for my current situation, it seems like the boxers burn more oil than conventional engine setups. Not sure if the oil consumption issues are just caused by the boxer layout, or these engines just need a hard break-in to get everything seated.
Anyhow I'm now debating on how to break in the new ride when it arrives (along with my new Tribeca engine as well). I guess the consensus here is to drive it like you stole it.
Funny in the BRZ manual it says that the magic oil burn number before Subaru thinks it's a warranty issue is 1.1qts/600 miles. On my Tribeca the number is 1qt/1200 miles. The 2.0 also takes 5.8qts total, a lot of oil for a little guy.
