I think Mobil used to rely on a third party to populate its "Oil Selector" tool, but it looks like they've retreated to recommending only what is in the OEM manual. Another example is the current generation of Hondas/Acuras: up until a month or so ago Mobil recommended 0w-20 or 0w-30, now only 0w-20 is listed. But I doubt this has anything to do with WalMart stocking habits.
