Is This Oil Any Good?

During my working career as a tech and sales manager I've been into almost every motor oil bottling plant in the US. Many international. I would bet this oil is formulated and filled by what's called a "co-packer". The co-packers fill for many companies like Wal-Mart, NAPA, Oreillys, Autozone or any of the the big box stores don't have a oil bottle filling plant. They are all done by co-packers. Not saying this is a bad thing because the co-packers know what they are doing.
Mobil, Valvoline and Phillips have their own blending/filling plants. As does Pennzoil.
I run Mobil in everything I own.
