Quaker State 5w30 at AutoZone

Thanks for posting @ensoniqman .

Currently at a AutoZone in New Mexico, not finding that flavor if Quaker State at this store, or any posted clearance pricing.

This is the time of the year one is most likely to find clearance oil at the big box auto stores.

I looked at a few more websites and it does appear to confirm this is a semi synthetic oil.
AutoZone may be incorrect
 
What's the difference between Quaker State Advanced Durability and Quaker State All Mileage?
Does the "All Mileage' have more seal 'conditioners' like high mileage oils?
At any rate I would have no problem using this oil for a 5K OCI in my 2 Ford Duratecs which spec. 5w20 if I could get some.
 
So check this page out. Its really hard to tell, but the black label is Advanced Durability or it used to be called that. It's blank now strangely. They say its a synthetic blend. I think almost all big name motor oil these days is blends as opposed to conventional, although sometimes you will see conventional in a description and in other places it will say blend. I bet they are blends, or at least a conventional that basically functions as a blend compared to the conventional of yesteryear.

To answer your question, it appears that all mileage and high mileage are very similar or the same. They both do the below three things. Advanced Durability doesnt have seal conditioners though.
