I was set to contradict you, but the MSDS for this product says it is 60-70% "1-Decene Homopolymer Hydrogentated...", which I gather is PAO. Interestingly, the same product in 5w/20 says nothing meaningful about composition. So it looks like M1EP 0w/20 really is different and perhaps better than other M1 products.
