Wal Mart oil is good oil. Like Motorcraft oil, some one makes it and bottles it for both.
This is true. I retired from the ExxonMobil refinery in Beaumont, Texas &, while I never worked at the Blending & Packaging Plant, I have seen it & knew guys that worked there. They put the same oil in different bottles or jugs for different customers. As long as the oil meets specs (& it does) it’s fine.
The same thing is true for gasoline & diesel fuel. They all meet the minimum octane & cetane requirements & NO MORE. These companies do not believe in “product giveaway”. Often these companies will buy fuels from each other to save on shipping & other expenses. For example, Chevron will by fuel from Valero because the Valero refinery & distribution center may be closer to several of their Chevron stations. They all do this & there is no problem because the fuel will be EXACTLY the same at the time of delivery. Obviously, there may be concerns about age of the fuel or water in the tanks, but these problems occur on a case by case basis at various individual stations & have nothing to do with brands.
