Exactly. They meet the same specifications, and it's not like PU allows for a longer OCI than PP (as compared to M1 EP versus vanilla M1). By the way, that's a great Amazon Canada link to show how useless that site really can be. Amazon Canada's own price on M1 0w-40 at $13.87 is obnoxious. One of their reseller's prices at $34.80 per litre plus $10.66 shipping indicates brain damage on the part of the seller.
The other option for the OP is to simply grab Formula Shell Synthetic from the distributor, if he's stuck on synthetic and doesn't need an officially licensed dexos1 product. He'll get it for about half the price of any regularly priced synthetic at Napa, CT, or Walmart.
If I want oil delivered, I'll talk to an Amsoil rep. Heck, even my RP supplier can get me that delivered cheaper than any of the Amazon Canada oils. If I lived 50 miles from a parts store or oil company distributor, I could see ordering from Amazon (like when I lived 150 miles from a bookstore, I'd order books from them). Otherwise, get real.
