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.

We're in for a synthetic oil shortage very soon, get them while they're cheaper and available.

Advance Auto has these at the same price but YMMV on inventory. Also, there is a rebate promotion for $5 back via Venmo or PayPal up to 3 rebates. It only applies to oil purchased from Advance, AutoZone, and O'Reilly's. I picked up 3 jugs of 5W20 from one of my local Advance and just submitted for the rebate.

The 5W20 Quaker State FULL SYNTHETIC at Amazon is less for $12.92 (better than synthetic blend) https://www.preppingdeals.net/dea...r-oil-5-qt

What about the MOTOR OIL SHORTAGE ? or the 30% PRICE INCREASE coming on motor oil ? Is it time to stock up ?
If I have a shop that changes my oil can I bring my own oil for them to use ?
What's the shelf life on motor oil ? I only change my oil every 2 years.....does new motor oil go bad, have an expiration date like a can of green beans and go bad over time ? I don't want to get greedy and stock up with a couple jugs if it goes bad in a few years.
Or maybe a motor oil shortage happens ? People start to panic and the price goes up to $80 for a 5 qt jug of oil ? Maybe I can sell the oil I bought for $12 and sell it on Facebook Marketplace for $60 ? Huh ? at $12 maybe I should buy 10 jugs ....I can flip it as an investment ?
