So I just did some more research and it is made by Coastal which is made by Warren. The same guys that make Wal Mart oil.
Wal-Mart oil is made by Warren Distribution, not Warren Oil. Two different Warrens.
Warren Performance Products (WPP) bottles ST, and a few other house brands.
Warren Oil(Warren Unilube) bottles American XT and Coastal oils, as well as the Advance Auto house brand oil. They are based out of Dunn, NC, I believe.
That being said, Ive actually used the AAP house brand oil for a 500 mile run to purge my 3800 after changing out the intake gaskets, worked fine if you ask me. Im sure it will be ok for a reasonable run, say 4000 miles.
