What’s going on with Quaker State Ultimate Protection?

[Carlostrece]

Which one would that be?

He needs to post the evidence he based his statement on before anyone should take his statement seriously. Let's see the evidence before believing anything.

Glenda is currently testing QS HM FS in her car. Would she be doing that if she thought QS is garbage? Clearly she must think it's a good, or likely good, oil. I look forward to reading her results when she posts them.

QSUP is no longer stocked at my local Walmart stores in the 5 quart containers. They still are selling quarts of it though. Bang for the buck -- its right there. QSUP 0W20 SP is up next for my Rav4 Hybrid in less than 1K miles.

Quaker State Euro 5W-40 that has a NOACK of 5.7!

 

[Bill7]

Quaker State has only 3 good oils', 2 of them are no longer available, the 3rd oil is still available, but it would hurt my gas mileage in my car and only be good in my Lawnmower.

You are likely referring to their Quaker State Euro A3/B4 5W-40. I still see it at my Walmart. It wasn't discontinued.
I was tempted to try it, as it would likely yield the best protection for extreme heat applications.

You are correct Bill7, you can still get this oil Online from Walmart, I believe this oil has a HTHS Number of 3.8

The QS UP FS data sheet for 5w30 still has a working link to download. That's the one I looked at 2 weeks ago and its specs are excellent. I also previously downloaded 0w20 & 5w20 data sheets 2 weeks ago and they are excellent too.

Tonight I notice that the links to 0w20 & 5w30 data sheets are now broken links. For some reason, there are now two 5w30 links - one broken & one working.

I think it's incompetant website management by QS or SOPUS website maintenance IT staff. I'm an IT manager myself. I recognize it as incompetance by whoever maintains the QS website. If it was intentional, they'd fix or remove the broken links, not leave them dead.

I don't assume the dead links mean the oil is being discontinued.

The incompetance of their website maintenance people has nothing to do with the people who make the oil or the products they make, IMO. Though it's not exactly a ringing endorsement of the SOPUS middle or upper management business office. They should be embarrased.

I attached page 2 of each data sheet (0w20 & 5w30) that I downloaded 2 weeks ago. I did not download the 5w20 data sheet 2 weeks ago and now its link is dead.

It is so similar to pennzoyl platinum 0w20

Except that PUP runs thin per grade. QSUPFS runs thick per grade. I prefer thick per grade, especially in a full syn oil.

Ultra 0w20 is thicker. Check their PDS, it is 8.8 and among the thickest 0w20's out there

Maybe. I don't know as much about 0w20. I'm more familiar with 5w30. Have you compared the two oils VOAs in the VOA library? The VOA will tell the actual vicosity in the test, which often differs from claimed viscosity in data sheet. I have compared the VOAs for 5w30. I've not compared them for 0w20.

He is correct. In 20 PUP is one of the higher ones even just a bit higher than QSUP. But 8.8 vs 8.4 is basically statistically irrelevant.

The VOA library is getting dated. I don’t know if I would trust all the info in there anymore. Formulations change overtime and if new tests aren’t being completed and updated regularly it is no longer relevant. There’s still some SN and SN+ data in there. I mean, that’s cool if you still got it hanging around, but if you’re buying new products off the shelf then very likely it is no longer pertinent info to base your decision off of.

3.4% fuel and 4,600 miles thinned it to 7.8. I think their pds claim of 8.8 is legit. And its TBN is a beauty. I feel pretty bad draining it out at 6.8 TBN

TBN can be dubious. You shouldn’t be looking to “use it all up” before you change the oil. I don’t even look at it. The oil was diluted and thinning so it was a good time.

When looking at datasheets and VOA tests of oils I've notice a few trends regarding cSt @ KV100. I only considered VOAs done by Oil Analyzers, not by Blackstone or others. This is because I think OA is the most accurate. Also it keeps the tests comparisons apples to apples when all brands of oils are tested by same lab.

PUP, PP, & PP HM oils VOAs always show much lower cSt @ K100 than is claimed on manufacturer's datasheets.

Same ^ with Mobil One oils, but not as large a discrepency.

Valvoline oils test same or only 0.1 less cSt @ KV100 than claimed in data sheets. So Valvoline's claims are accurate.

Quaker State oils tests always show higher cSt @ KV100 than claimed in datasheets, and the datasheet claims are high.

That is why I said Quaker State oils are good oils with superior full op temp viscosity. That's true for all QS oils, and especially for QSUPFS which is QS thickest FS oil. It's additives are good too.

QSUPFS also has either a strong mix of GTL or is fully GTL. I'm not sure which. Either way it's a great oil and only $20 a 5 qt jug. It's a great deal. It's even rated for extra sludge prevention and a 20K OCI.

 

[Carlostrece]

I just noticed that all QS oils (QSUPFS, QSFS, QSHMFS, & QSHM) have broken links to the data sheets. So it's not just QSUPFS that has that problem.

It's a QS website wide issue. The fact that it's an ongoing problem indicates to me gross negligence by QS/SOPUS website maintenance/management dept.

I'm an IT manager where I work. I recognize this as an IT problem, NOT an intent to cancel any QS oils.

I will attempt to contact Quaker State management to report the broken links, but I shouldn't have to. QS management or IT dept should be proofreading, testing, finding and fixing these things in a timely manner.

Even so, I do not think this refelects on the people who make the oil or the quality of the oil. I still believe in their oil.

 

[Carlostrece]

I reported the datasheets broken links by telephone to a QS oil tech support guy who assured me he'd report the problem to the IT dept and the business office who the IT dept answers to. He also thanked me for reporting it.

It will be interesting to see how long it takes for the links to get fixed.

 

[facility1]

I too called Shell about their pds/sds links and told them about this issue, and they apparently did not know about this or the guy on the phone was just acting dumb about it.

Meh, the HT/HS is a better metric and is backed up by the approvals the oil holds or does not hold.

Well, Castrol GTX full synthetic 0w-20 has a number of 9.0. They may be garbage otherwise, but at least PDS wise, that is pretty thick for 0w-20.

Are you sure? It is 8.1, Amsoil 0w16 is 8.0

I am looking at the Castrol GTX full synthetic 0w-20 Not Amsoil, Pennzoil or Quaker State. Castrol GTX full synthetic, not their Edge products. Anyhow, I have it here in my hand. I printed it off the Castrol USA website last Thursday, 6/19/2025. The ASTM D445 at 100c reads 9.0
