Motor Oil Engineering Test Data
Just spent an hour and half reading about motor oil’s.
It goes though oil with high zinc and modern oils with lower zinc. It goes through the additive packages.
It was very interesting, especially when I read that Quaker State Full Synthetic 5W30 was rated #1 in shear strength when compared to 268 different oils.
The test says that todays modern additive packages in some modern oil’s exceed the popular high zinc oils by a fair amount.
I’m posting the link here so others can read and comment about the study.
