The answers that were given were to "change my own oil", "tests are $5,000", and that "Synthetic is not required". I acknowledged all answers and challenged only the one that is directly below this reply (not knowing that there was in fact a turbo model Forester). IMO people learn by information and I was given that information challenged the opinion and got more information to which I now understand.

And who's definition of synthetic are they using? Not the API's because they don't have one. And replenishment with 5W-40 conventional is allowed? There's NO such thing! In an email newsletter, SoA said that the new Impreza requires 0W-30 conventional. No such thing as that either and the Impreza specs 0W-20 synthetic. The Outback's manual says synthetic may be used but you have to stick with it if you switch to it. 1980's logic. I'm not suggesting that you run only conventional, but a 3k mile run isn't going to hurt anything.

My apologies I don't know to much about Subarus other vehicle lineup. Thank you for your input...
