Fail, the test was not even cold enough to get some bottom tier oils into the cloudy region, he needed another -15f. At this point some oils were slow just because they were thicker viscosity, lol. Good info as in at -5f all of the oils will protect you were powered by an oil pump, bad news is he wasted a lot of money to show a test before the fail points of half of those oils. Guess he was working with what he had, but you need to be at -20f and beyond to start seeing cloudy oils and failing oils in cold flow.
