Walmart seems to be out of stock of the 5 quart jug for $27.97, anyone find it for that price anymore...anywhere?

Walmart has the quarts of the new PUP for $7.98. That's not earth shattering but it's a pretty descent price. Buy 5 quarts and the shipping is free

Wait a second, this stuff is pretty cheap right now. Are you saying this provides near the same protection as PUP? Any oil nerds have some input on this?

It sounds like vincejr was talking about Penzoil Platinum and not Ultra Platinum.... unless I am reading it wrong. That said, I changed the oil in my Veloster after a couple hundred miles of ownership and I switched to Royal Purple and it seems to create some interesting noises that I can only relate to lifter noise. Changed the oil 3k miles later to PUP and the noises went away and everything is driving well. I would be curious to see some oil nerd data on the Quaker State Ultimate Durability as well though. Always intersted in putting the best oil money can buy into any of my vehicles.
as far as price, I use Amazon Prime Subscribe and Save and end up paying $7.73 per quart.

I don't think this was always the case... but at this point, I would have to agree, just based on the experience I had with my VT. So far I am happy with the PUP and with 3k mile oil changes, I think I am likely in good shape.

I found a new white paper on LSPI and the PQIA site has the Virgin oil analysis of Quaker State Ultimate Durability on it.
Rat540 also liked the QSUD for it's 120k PSI film strength that didn't drop off even when he raised the test temperature from 230s to 280s.
The LSPI paper tested 20 or 30 oils and ranked them by % of LSPI events during a test. Details of the test I forget.
But the bottom line was they came up with an equation that is based on the amounts of certain additives. If the equation had an output value of -.5 or less, like -3... Then the oil was significantly better at not causing LSPI.
There were 4 factors in the equation total that were tied to this number. The two I can remember we're Calcium and Molybdenum. In a nutshell high Calcium helps clean the motor but if you have high Calcium then you need a correct ratio of moly to keep LSPI from happening. Without moly LSPI was higher... But with too much moly, the oil would not clean the motor.
It was a damn good white paper.
I will dig it up....
I'm sure that either PUP or QSUD will be quite fine in VTs.... No need to worry or scramble.

You're mixing the QSUD grades vs. results up, V. 0W-20 and 5W-20 were both above 121K PSI, but 5W-30 was at 113K PSI. The first two dropped off a lot more than the 5W-30 when tested at 275°F.
As I said long ago in the anti-LSPI thread, Calcium (contained in additives) has the biggest negative effect and conventional (Group III) oil is second. Ester has the highest resistance and PAO is next-highest.
Magnesium additives to replace Ca additives were shown in one SAE research paper to increase resistance to LSPI, but very few oils have Mg instead of Ca.
Time to look at the latest set of articles on SAE.
All the others I've looked at show Mo content has minimal effect on LSPI prevalence, so let's see the one you've found.

Yep I did get the grades mixed up, working from memory, thanks for the heads up. But all of the QSUD variants were 124k thru 113k PSI, so not a big spread, I might have just mentally averaged them to 120k. The part about super heating the 5w-30 and it not breaking down below 109k PSI was what really caught my eye, I'm thinking this is a useful oil property for within the super heated internals of the turbo itself.
Let me see if I can find that white paper / lab report I stumbled across...

I didn't find "the" article. But I did find the patent application where they discuss the balancing of the ratios and using moly to reduce LSPI. Calcium and Sodium in concert together is big bad. Moly does something that reduces the LSPI. Heres the link and just the beginning of the abstract from top of page:

Cool. You know, while the 540rat page has some great info, the vast inconsistencies in the results for each oil tested are rather disturbing. Some chems are listed, others aren't, others have more chems or less chems, some were tested at high temps and some weren't! Not having the date tested is annoying and it's hilarious that certain (older) oils treated with Prolong have the highest wear ratings. Imagine if he tested CERMA oils and other oils mixed with CERMA oils.
It would be much better if it were in a spreadsheet format with consistent/complete data for all oils tested. The huge monolithic page with results scattered throughout is not indicative of an engineer's work. Maybe he's just old school and doesn't know how to use Excel/OpenOffice.org to properly maintain a list that's easier to see all test data without jumping back and forth and searching throughout the page.
Thermal breakdown results:
5W30 Pennzoil Ultra Platinum, API SN, GM dexos 1 approved, synthetic = 290*F (high temp tested late 2015)
5W30 Quaker State Ultimate Durability, API SN, GM dexos 1 approved, synthetic = 260*F (tested late 2015)
Wear rating results:
15.*5W30 Quaker State Ultimate Durability, API SN, GM dexos 1 approved, synthetic (gold bottle) = 113,377 psi
zinc = TBD
phos = TBD
moly = TBD
This was the latest current version of this oil when tested at the end of 2015. The psi value of this oil, which came from testing it at the normal operating test temperature of 230*F, put it in the INCREDIBLE Wear Protection Category.
However, I went on to also test this oil at the much higher temperature of 275*F. At that elevated temperature, any hotter and thinner oil is expected to experience a drop in Wear Protection Capability. But, this oil only had a very small 3.7% drop in capability. And even at that elevated temperature, it produced an extremely impressive 109,211 psi, which still kept this much hotter and thinner oil in the INCREDIBLE Wear Protection Category.
48.*5W30 Pennzoil “Ultra” Platinum, Pure Plus Technology, made from pure natural gas, API SN, GM dexos 1 approved = 99,039 psi
This oil was introduced in 2014, and comes in a dark gray bottle with a blue vertical stripe on the label.
zinc = TBD
phos = TBD
moly = TBD
The psi value of this oil, which came from testing it at the normal operating test temperature of 230*F, put it in the OUTSTANDING Wear Protection Category.

At that elevated temperature, any hotter and thinner oil is expected to experience a drop in Wear Protection Capability. But, this oil had only an extremely small 2.7% drop in capability, the smallest drop I have seen. And at that reduced value down to 96,363 psi, this much hotter and thinner oil was still in the OUTSTANDING Wear Protection Category.
Why no results for Castrol Magnatec (rhetorical)? That seems to be an interesting oil that sort of does what CERMA does, bonds/adheres to metal surfaces.
Anyway, I'm going to be revising my anti-LSPI article in a few weeks, taking the wear aspect into account and some other new info I've recently found regarding carbon/additive deposition. It won't be posted here, though...

As far as Mo goes, you can't take one article and assume it's correct. Far more studies have shown that its presence or absence doesn't really make an oil more or less prone to LSPI. Ca is the crucial element, but it also depends of the type of Ca compound!

Thats not PUP, it's PP.
I got the QSUD because it's a deal right now at Walmart online. $20.24 for a 5 qt jug.
