I talked today to a guy in Toronto, Imperial Oil's HQ - lubricants and specialties division and was told that M1 SS 0W30 is starting to be available in Eastern Canada now, it's just a matter of few weeks, maybe a month till they start trucking it out West. Apparently Imperial Oil (Esso) will be bringing it from US for now, maybe later they will start producing it locally. Price-wise he wasn't sure how much it will be. After reading some more and considering your input I've decided to give this 0W30 a try. Winter is coming, cold starts, low temperatures. Still not sure which one, though: Mobil 1 or Amsoil 2000 series.
