Oil Information Blog

[VVSidewinderVv]

I just wanted to throw this link out there as something I use for picking a synthetic oil for my vehicles. Having had a modified Subaru WRX STI which had a small oil capacity on a high strung high boost engine I felt oil choice was extremely important. I think this guy is spot on with his research so I'm posting it here for you all to read or not read as it is an incredibly long document .

I take no credit for this. It's just something I feel is an important resource for anyone looking to protect their engine as best as possible.

Incredibly long is an understatement! I made it through a few pages, some good info for sure.

So in summary, oil is good to have. Some oil brands are better than others. Words.

Idk I’m not a literary cardiologist and didn’t read it

Haha! Yeah it is. And it gets pretty technical Somewhere like 1 /6 of the way down he actually begins the ranking list and you can search "wear protection ranking list" to find it. And he categorizes them like this. Some of the best you can buy pretty cheap to. Interesting stuff as far as oil goes.

It's more like specific oils from specific brands are better, but that's the gist of it.

Never would of guessed Quaker State would be at the top of the list.

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

This was my big takeaway…

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

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.

Thanks for posting! I was skimming through and noticed he had this section about gas also and thought it was interesting he specifically referred to the Bronco...

And all this time I just assumed synthetic oils were similar. On a side note since I'm still waiting on our Raptor. Does anyone know if the oil change mileage/timer pop warning is set for synthetic or regular oil. I've used synthetic in our Rubicon since we bought it in 2016 and just change oil when it says it is time to do so but not sure if the alert is set for regular or synthetic. I just figured since synthetic lasts longer it couldn't hurt to change it more frequently. I'm pretty anal on keeping the oil and filter changed regularly.

Yeah. I agree with it, but his answer doesn't explain the intracacies of it all.

Ford engines detect octane by using the knock sensors and adjust several ecu parameters using what they call the Octane Adjust Ratio that works as a multiplier from a value range of -1.0 to +1.0. If the knock sensors detect knock the OAR goes positive causing the ecu to adjust and pull timing and other parameters. If using a high octane fuel the OAR will adjust negative, until it starts to detect knock, all the way to -1.0. So by adjusting timing, etc. The OAR essentially auto tunes (to an extent because it can only go to -1.0) the engine to provide more power at higher octane.

Not all engine ECUs have this capability so just having higher octane in a Prius will not just give it more power. It would need to be tuned to take advantage of the higher octane.

There are other benefits to higher octane fuels depending on the manufacturer as well. Companies like Shell put additives in their 93 octane that provides some cleaning action to your engine internals.

Got a friend that has a 1987 Mercedes Benz sedan with 438,000 miles on it. He uses conventional oil and changes every 3500 miles. Runs like a top and he has used O'Reilly's brand for a while now. I think it's more about the maintenance schedule with an oil that meets the standard. Getting that granular in the details of one oil over another is just overkill in my opinion.

Hell my brother has a 2001 F250 with 215,000 miles and he just goes for the SuperTech Walmart oil.

I guess if I were racing cars, and putting them thru extreme torture the details in that article might mean a little more to me.

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

At least with my GM truck that meter uses some sort of algorithm based on engine usage. If I run it hard it drops faster than if I drive it normally.

Regardless of this, I use synthetic oil only and on a turbocharged engine I changed the oil every 3000 miles. On my non-turbo V8 truck I do 5000 miles. I would not run anything other than full synthetic on a modern engine because they run such tight tolerances.

I ran my WRX STI and BMW 335i hard. Their oil was filthy by 3000 miles. Turbo engines run hotter and get oil dirtier much faster. BMW still recommended synthetic and 15000 mile oil change intervals. I can only imagine how nasty that oil would look coming out.

I think he lost some credibility with me on this section about K&N air filters. There are too many other studies showing it allows too much dirt through


48. Can street vehicle performance be increased by switching to a low restriction K&N air filter?

Let me say right up front, that I have no connection to K&N air filters at all. So, their sales success does not involve me in any way. But, the performance improvement that their air filters provide, makes it worth letting my Blog readers know about this, if they don’t already know.

Some Automotive enthusiasts may think that low restriction K&N air filters only benefit Hotrods and Race Cars. But the truth is, the performance of street vehicles can also be increased by switching from a restrictive factory paper air filter, to a low restriction K&N air filter.

And there are those who might be concerned that low restriction air filters may allow dirt in. But, they would let dirt in only if they are used “dry”. The K&N free flowing cotton gauze design requires that they are coated with the required K&N oil. And all new K&N air filters come right out of the box, already pre-oiled from the factory. So, you don’t even have to be concerned about putting the oil on them yourself. The oil coated cotton gauze makes it perfectly fine to use a K&N air filter on street vehicles.

You don’t have to use the oil yourself, until the time comes to re-oil the filter after cleaning it. K&N offers the cleaning solution and the filter oil. Though many people don’t want to bother with all that, so they simply put in a new K&N air filter when the old one needs to be cleaned. So, you have that option as well.

A normal street application in the real world, would typically require the filter to be cleaned and re-oiled, or else replaced with a new one, every 20,000 miles or so. But, the actual calendar interval really comes down to how many miles you put on per year, and how dirty/dusty your driving conditions are.

Countless people, myself included, have been using K&N air filters for many years on street vehicles with no problem at all. And of course the main point is that they increase the performance of all engines, including street engines, compared to using the much more restrictive factory paper air filters.

That is when he started the blog but he keeps adding to it. The stuff about the Quaker State oil mentioned above was done in 2021
