Warren oil has to be one of the best blenders in the industry. I'm very surprised to see them to be the first one out with a certified product.
This shows that they have been working on developing it for a while. 0w16 will be the new 0w20 in 10 years.
They just bought a recipe and materials form Lubrizol, Afton, Oronite, or Infineum. Anybody know which? Base oil could come from SOPUS, XOM, and I don't know who else.
I would say Warren has hero status, but they just blend.
