Pennzoil motor oil

That is not Ultimate in the video. Not that it matters much now, the war has likely killed off Ultimate entirely.

It's not... But no matter what "tier" of oil between Pennzoil & QS, they always test different.... which was part of the earlier discussion of this thread.

I've been a "Quaker hater" for a couple decades now... but I'd LOVE to find some QS Ultimate in 5w-30. However, it appears to not be available anywhere. I was a PUP fan myself, but I'm wanting something thicker now for my truck. Outside of boutique oils, this QS Ultimate was looking to be the best option for me... But it's ultimately unobtainium.
 
Quaker State Full Synthetic is the replacement for Quaker State Ultimate Durability. Quaker State reformulated its product line. Ultimate Durability has been discontinued. The bottles labeled "Full Synthetic" contain the current oil. Any remaining Ultimate Durability bottles are older stock.Ultimate Durability was SN or SN Plus and ILSAC GF-5. The newer Full Synthetic formula is SP and ILSAC GF-6A.

For the couple dollars more -- Quaker State Ultimate Protection which is Quaker States top the line product is well worth it. The Quaker State Ultimate Protection is totally a sleeper oil. Anybody that has not tried it atleast once -- should!!!

I understand that it does extremely well in the Noack Volatility test, too.

I followed your advice and therefore didn’t buy enough when I could. Also went all in on Stellantis and Oracle on your advice. 😱

No wonder I blocked you yesterday. 😜

That’s correct and occurred quite a while ago, we are discussing (at least I am) Ultimate Protection which is not the same thing. It’s a QS 20k oil.

Shame on Shell for using Ultimate twice, there’s been a lot of confusion between QS oils even on this board, which is definitely more savvy than the majority of casual oil buyers.

I don’t think that’s exactly the case. I think QS Ultimate Protection was what replaced Ultimate Durability
