Lol...exactly! BITOG is least useful for discussing...you guessed it...oil. It's awesome for discussing which washer to buy. WAY too many people overthinking it. PAO, base stock, GTL, etc impart certain qualities to oil which in the case of cold pumpability can be summarized by its winter rating. When you start trying to decipher the tea leaves of GTL vs PAO and cold properties within say 0W20's, well that's a fool's errand. At the end of the day, all 0W20's should perform similarly with respect to their cold properties regardless of PAO, GTL, base stock, etc.
