TL;DR — I skimmed the article and looked at the top of the Wear Protection Ranking List.

This was my big takeaway…

The real MVP here.

I never turn away the opportunity to learn, but there is more to it than just extreme pressure protection. There are additive packs to address various things such as corrosion, detergents, anti-foaming, dispersants...yeah lets just stop there.
I think if you want to go down a rabbit hole, just open up BobIsTheOilGuy and go nuts. The general consensus is just about every major player in the synthetic oil market puts out a quality product and you can't go wrong if using 5k mile OCI. With that said, many of us have our faves based on our experience and we will die on those hills.

Regular maintenance and good products is all I do. I will stick with Pennzoil Synthetic and Motorcraft filters every 5K miles. Easy to get and fairly inexpensive.

I am on the self service band wagon, no service plan or quick lube.

I would say that motor oils have changed to some extent since 2013... when this was written...

He updates it continuously. The #1 oil was tested spring of 2021.

He does address additives and such in the blog and provides those numbers in his ratings. I really just posted this as "interesting" information regarding oil to help anyone make a more informed choice if they are looking for info. I know none of it is the end all be all and that any decent brand of synthetic will work. Still I try to go for the best I can get at a reasonable price.

The “WEAR PROTECTION RANKING LIST” itself, begins here:

1. 5W30 Quaker State “Full Synthetic” (abbreviated QSFS), dexos 1 Gen 2, ILSAC GF-6A, API SP = 152,674 psi

And that psi value sets a WHOPPING NEW ALL-TIME RECORD for motor oils that I have put through my Engineering Torture Test on motor oil. It was tested in Spring 2021.

This new 5W30 Quaker State “Full Synthetic” motor oil replaces the previous 5W30 Quaker State “Ultimate Durability” (abbreviated QSUD) synthetic.

zinc = 905
phos = 764
moly = 176

The psi value of this new oil, which came from testing it at the normal operating test temperature of 230*F, put it in the SPECTACULAR Wear Protection Category. However, I went on to also test this oil at the much higher temperature of 275*F. At that elevated temperature, most hotter and thinner oils typically experience a drop in Wear Protection Capability. But, even at that elevated temperature, this oil produced an extremely impressive 148,133 psi, which was only a small 3% drop in capability. And that value put this much hotter and thinner oil in the AMAZING Wear Protection Category.

I also tested this oil to find out its onset of thermal breakdown, which was 290*F.

This new oil was purchased at Walmart. And its truly amazing performance is further proof that Walmart is selling legitimate motor oil, even though their prices are extremely low compared to typical Auto Parts Stores.

Many of us who have been devoted users of the previous Quaker State “Ultimate Durability” motor oil, were concerned that Quaker State’s Corporate bean counters might get their hands on this new Quaker State “Full Synthetic” oil, and cut costs that would ruin the oil. Fortunately, as it turned out, that did not happen. And in fact, now this latest new 5W30 Quaker State “Full Synthetic” motor oil, is BY FAR, the BEST PERFORMING motor oil that I have ever tested. This is absolute proof that Quaker State REALLY knows how to formulate motor oil.

This new “Full Synthetic” motor oil has set the bar so high, that it is the oil I will be using in my own vehicles from stock to High Performance, from now on. And it is the motor oil that I will recommend to my Blog readers for most water cooled, gasoline powered engines, that can use 5W30. This is especially THE “go to” motor oil for traditional flat tappet engines to provide the utmost in protection against wiped cam lobes.

Never say never, but it is hard to imagine another motor oil ever producing numbers this amazing.

Here is a back to back comparison of the new 5W30 Quaker State “Full Synthetic” and the old 5W30 Quaker State “Ultimate Durability”.

NOTE: The Higher the psi value, the Better the wear protection capability. And the Higher the onset of thermal breakdown value, the Higher the oil temperature can reach before the oil begins to deteriorate due to heat.

QSFS at 230*F = 152,674 psi
QSFS at 275*F = 148,133 psi
QSFS onset of thermal breakdown = 290*F

*****
QSUD at 230*F = 133,125 psi
QSUD at 275*F = 115,764 psi
QSUD onset of thermal breakdown = 275*F

The only possible concern about this amazing new 5W30 Quaker State Full Synthetic motor oil, was that it might be “too good” for use in wet clutch motorcycles. But, motorcycle Owner feedback in July 2021, proved that this amazing new motor oil works just fine in wet clutch motorcycles, meaning there was no clutch slipping at all. Of course that applies to wet clutch motorcycles with clutches that are in good condition.

Since 5W-30 is the oil recommended in the Bronco owner’s manual for both engines, albeit synthetic blend, the 5W30 Quaker State Full Synthetic seems like a pretty good option for protecting the Bronco engine. Personally, I prefer full synthetics anyway.

I generally stay away from these threads, they are like politics except instead of two candidates which are either heaven sent or the devil there are dozens. I've used QS for over 40 years with no lubricated engine component failure, so there's that. I now use QSFS and plan on using it in my first Bronco oil change. The QS website does not list meeting Ford WSS-M2C961-A1, but it does meet SN Plus and SP.. Do we suppose there is just a time lag getting the info updated?

Good question. I don’t know for sure, but I did find this, while searching for an answer…

Post in thread 'Ford 2.7L Ecoboost - API SP vs Ford WSS-M2C961-A1 + Pennzoil'​

​

“WSS-M2C961-A1 is pretty much ford's rebrand of API SP with ILSAC GF-6A, the manual says that the minimum is API SP with API certification mark which means ILSAC GF-6A API SP 5W-30 is the minimum you should use, I'd use any synthetic 5w30 oil that meets Dexos1G2 along with API SP in the ecoboost.”​

And the Technical Data Sheet for the Quaker State Full Synthetic SAE 5W-30 Motor Oil says the following, so it may not be relevant…
