True, the rebate on the mobil 1 oil makes this a meh deal.
That said, when the oil shortage hits (like in the internal autozone memo), synthetic blend will be good enough. If you change your oil every 3-5k miles, synthetic, blend or dino won't be much of a factor.
The smart ones will get some jugs for a few future oil changes.
