I just posted my UOA for the TropArtic 5W-30. I was shocked to learn there is (may be?) antifreeze in the crankcase!!! OUCH!!! @#$%!!! Where could it be coming from? I haven't observed any loss of coolant from the reservoir...could it be coming from somewhere else without showing up in the overflow tank? I am disapponted to say the least. What do I need to tell the stealer when I take it to them, and is this usually covered under warranty (which I did buy an extended one when I bought the truck)? Other than that, what are your thoughts on the other numbers, notwithstanding the leakage? Does it seem to be otherwise holding up well, or are there other concerns? TIA!!!
