Tomorrow morning is supposed to be -30C here, which happens to coincide with the CCS testing point for 5W-xx. I still have Pennzoil Ultra 5w30 in the Expedition at the moment with several thousand Km's on it. Given that we know that cold temp performance degrades with use, I wonder how far above the limit the lube in the sump might be?
I'm not concerned about it starting. It started last year in the same temp with a much weaker battery than what is in it now. I am however interested in just how poorly the oil flows at that temperature with some miles on it.
