break in questions
I wouldn't really suggest changing the oil until whatever it is that Subaru recommends. There is no reason to waste perfectly good oil. I would aim for around 5,000-6,000 miles between oil changes on our turbo Subarus when using Mobile One. I would submit every other or so sample of oil to blackstone-labs.com for oil analysis to make sure everything was happy with the engine and oil. I'm aiming for a 7,500 interval with the Acura pending oil analysis from the second oil change after switching to Mobile One.
If you like to be obsessive I would suggest the services of blackstone-labs.com.
Here are two sample report from my '02 WRX and '04 STi:

Hopefully not turning this into another dreaded "oil change interval" thread, but I definitely agree that people are far far far overzealous with oil changes -- to the point of wasting perfectly good oil and perfectly good money. You DO NOT need to change your oil every 3000 miles.
As far as your question goes: No.

Well on a brand new car, it doesn't hurt to change it after the first 1000 miles, after that, then yes, I agree, no need to be super overzealous about oil changes.

I'd get myself a beer and call it a day.

There is a very effective oil filter in your vehicle to catch any possible debris and metal pieces that might be dinging around. There is no doubt that there are trace elements that are going to be in the oil that are characteristic of modern engine break-in that oil filter might not catch. These particles aren't "pieces" nor are they "tiny" but they are microscopic in size.
I just pulled the factory oil out of our new TL at 7,000 miles and there wasn't a single particle or any metalic sludge on my magnet thanks to the oil filtration system.
Consider that even Subaru which is going to to encourage you to patronize your local Subaru Service Department as much as possible recommends the same interval for the first oil change as when the car has 100,000 miles. That fact in mind realize that as the engine ages your oil change interval should actually progressivly shorten over the life of the engine.
