In Edmonton, we have many many days of -20 and colder, and quite a few nights where -30 is broken. The only thing the Mobil 1 in my crankcase is hurting is my wallet.
I do agree that synthetic oil is a wast of money, especially among us that change our oil frequently. I got into the sythn habit with racing motorcycles (350F oil temps and higher...) and just can't shake the addiction....
