2001 Outback 2.5 with 5 Speed
If it gets that cold where you are, I would recommend a 5w30 over the 10w30. The 5 weight will flow easier for your rough cold starts. You could even run something like an synthetic 0w30 from Mobil 1.it gets pretty cold here, but i don't think that it gets nearly that cold. i guess it is kinda useless. i am planning on running mobil 1 10W30 this winter. i would run 0W20 but costco doesnt have that.
