If you want American oil from a big name, you can't get much more American than ExxonMobil, headquartered in Texas, massively vertically integrated and produce a significant portion of their own components.
If you are willing to spend a bit more, @High Performance Lubricants is a board sponsor and based out of Illinois. They will ship directly to your door. AMSOIL is another option, and their OE and XL oils are reasonably priced.
