Dealer is going to fix issues (supposedly). From the dealer: hi travis, I did notice when I was driving it that the revs dropped occasionally but it didntworry me as it only happened very rarely. I spoke to my Subaru guru and you are on the right track with the maf sensor and the oil smell is probably the lower rocker covers as the always leak as they are laying flat being a boxer motor. if you can drop it of to me and leave it for a day or 2 but please give me at least 2 days notice as they can be busy.
