I should add that we've spent a lot more time on Wal-Mart's house brand, and it's still up in the air as to what exactly that is. It was made by the QS subsidiary in Shreveport and speculation is that some production will be shunted to Shell to make up for the departure of Texaco (Equilon), on the other hand there is also evidence that some of it is Warren out of Omaha the manufacturer (and it IS labeled) of Sears Spectrum oil.
