Spoke to my automotive instructor (Owns a successful shop + ASE Certified + 30+ years of experience) and he says that it sounds like a normal Subaru in the cold. He says that, as long as the smoke looks good..no loss of power, than it's good. He recommended when I lose 1qt of oil or next oil change...to replace 1 quart of oil with 1 quart of Mystery oil.. to clean it up. I'm guessing this case is closed. Hopefully it's all accurate! Thanks everyone.
