Bumping this old thread again...still available with the new ESP X4 formula if you click on "$35.99 Mobil 1 Bundle" (
https://www.autozone.com/motor-oil-a...rt/1177215_0_0) that was recently DexosR certified:

$72 + tax for 10 quarts of warranty approved oil and you might be able to return the 2 oil filters to get some money back but that isn't guaranteed.
There's always an expiration date listed for the deal but AutoZone has been perpetually renewing it for years as far as I can tell.
