At my local Wal-Mart, a no-name brand with the "SF" label is taking up space on the shelf. This is happening while the stock of M1 and Chevron seem to be getting less and less in recent weeks. Hopefully, this is a Christmas thing. Who buys SF rated oil anymore? Why would anyone want SF quality oil for anything? I'm frightened that some guy who usually picks up the ST house brand will find this a better "value" and use it in his new SUV. Then forget to change it for 4000-5000 miles.
