    Open your hood and read what it says on the yellow oil filler cap. That is what kind you should put in.

    Every motor is a little different, some consume more oil than others. I have heard other WRX owners complain that their car can burn as much as 1qt of oil over 3k miles. If your car burns this much, try switching brands, that sometimes helps. If it burns more, I would start looking for the problem.

    I got Rex used coming off of a lease, and the person only ever got things done at the dealer, which used conventional. If I bought it new, you better believe I'd have synthetic in that sucker from day one, but ce la vie.

    I stick with 5w-30 Mobil 1 conventional year-round (in NJ). I actually use the Clean 5000, which is an extended life 5kmi conventional. I do a lot of highway-type driving, so it's perfect for me. Never had a problem, and things run super smooth and super clean. I considered switching to synthetic merely due to Mobil's guarantee that mixing theirs has no problems, but the old-schooler in me can't get over the seal swelling mythos.

    In all actuality, whichever brand you like, just make sure you stick with it, as each company's blend is a little different.

    Sorry to open an old thread but i also have a 2004 Subaru WRX Ej205 2.0l turbo , i worked at the Subaru dealership as a mechanic and you can use just regular 5w30 motor oil in it. I was told anything up until 2007 turbo or non turbo can use regular engine oil. With that being said i still run synthetic oil in my Subi, i have always used Mobil 1 but just recently i keep hearing a knocking noise from the motor which is no bueno at all. So i am switching to Valvoline 5w30 synthetic. Should i be using a thicker weight oil? other than 5w30 only 60k on her? I just heard its bad to switch from synthetic to conventional.

    Valvoline VR1 is an excellent oil. Whether or not you should be using a thicker weight would depend on operating conditions, and how your oil pressure is behaving (as well as UOA results).
