Does anyone know where I can find spec sheets for Quaker State Ultimate Durability 0w-20 and Pennzoil Platinum 0w20? Both brands used to have spec sheets for all their oils on their websites, but I can't find any since they redid their websites. I'm interested to see how the viscosities compare between the two. I've seen VOA's of their 5w-20's already and I imagine additive wise, the 0w-20 should be pretty similar. I was surprised to see my local walmart start stocking Pennzoil Platinum 0w20, but I was even more surprised to see them start stocking Quaker State Ultimate Durability 0w-20 when I stopped by last night to get some of the PP.
