Which dealer in MA was this? As for break in oil, I would run conventional 5w-30 @ a 3,000mi oil change interval, or less if that makes you feel more comfortable. The only problem with standard 5w-30 is that turbo subie motors shear down the oil to a 20wt fairly easily, so as long as you don't stretch your oil change interval you're ok. I'd probably change to synthetic after 5k or so.
