Arrghhh! Another oil thread. I'll jump in late. I can't help myself.
If anyone has independent lab tests they can link to, we all would appreciate it. I looked through the web site and did not find any SAE papers (although they display the SAE International logo at the bottom of their page), or similar papers showing test results.
So I went looking for other test results. I found many test results at the "540Rat" blog on oil testing. He is an ME and racer, and started conducting and documenting his own testing about 10 years ago. Although his writing tends to be bombastic, From what I can gather on his site and others, his testing data is accurate.
It's a mixed bag of results. The wear resistance of some oils with the Oil Extreme added goes up significantly--up to 56%-- whereas other oils have little change or go down with the OE additive. The trend appears to be that relatively low scoring petroleum oils generally increase in wear resistance significantly, whereas high-scoring synthetics with have little change or go down slightly.
NOTE: The dozen of his top rated oils are all above 130,000psi. None of the results of oils that improved with the addition of OE got anywhere near that, with the top result being 111,570psi at #55.
Your quick take-away: "It depends" on the oil you add this stuff to. If you already use one of the oils highly rated for wear resistance by 540Rat, then the additive does little or decreases the wear resistance rating. If you use one of the lower rated conventional or semi-synthetic oils, then it
might help significantly. Or hurt. Or not make any difference.
Here is an excerpt from the 540Rat blog, although there are many other test comparisons further down in the blog (too much to quote here):
.
55. “Oil Extreme concentrate” added to 5W30 Pennzoil Ultra, API SM synthetic = 111,570 psi
This oil on its own WITHOUT the “Oil Extreme concentrate” added to it, has a wear protection capability of 115,612 psi. But, with 2.0 OZ of concentrate added per qt, which is the amount intended for racing, its wear protection capability “WENT DOWN 3.5%”.
zinc = TBD
phosphorus = TBD.
moly = TBD
calcium = TBD
TBN = TBD

56. “Oil Extreme concentrate” added to 10W30 Brad Penn, Penn Grade 1 semi-synthetic = 111,061psi
This oil on its own WITHOUT the “Oil Extreme concentrate” added to it, has a wear protection capability of
only 71,206 psi. But, with 2.0 OZ of concentrate added per qt, which is the amount intended for racing, its wear protection capability “WENT UP A BREATH TAKING 56%”.
zinc = TBD
phosphorus = TBD.
moly = TBD
calcium = TBD
TBN = TBD

.
57. 5W30 LE (Lubrication Engineers) Monolec Tetra-Syn, API SN, GF-5, dexos 1, synthetic = 110,883 psi
zinc = TBD
phos = TBD
moly = TBD
This oil was tested Spring 2018.

58. 5W30 Oil Extreme Motor Oil, API SM synthetic (per the Oil Company, even though synthetic wording is not shown on the label) = 110,286 psi
The Company claims this oil contains their proprietary formula of calcium petroleum sulfontate EP (Extreme Pressure) technology that is NOT found in any other motor oil. They also claim that it will provide 5 to 7 more HP, 7 to 10% better fuel mileage, cut engine wear in half, and will extend drain intervals two or three times safely. This oil is endorsed and promoted by Tech Author David Vizard. And he was so impressed by this oil’s performance that he also became a share holder in the Company. The results from the “Dynamic Wear Testing Under Load” performed here, fully supports their claim regarding wear protection. So, their hype about that, turned out to be absolutely true. And since this oil beat nearly every high zinc oil I’ve ever tested, it also proved another one of their claims, that using zinc as the primary anti-wear component, is outdated technology.
zinc = 765 ppm
phosphorus = 624 ppm
moly = 52 ppm
calcium = 7,652 ppm
TBN = 23.2
.
Just for fun, here is the test result of Yamalube 15-30, which was the
last on the list. Clearly, its claimed JASO MA rating was false:
298. 15W30 Yamalube, Performance Full-Synthetic with Ester, Motorcycle oil, JASO MA (Gold Bottle) = 0 psi, yes 0 psi, that is NOT a typo. This oil was tested several times, exactly the same as every other motor oil is tested on this Blog. And this oil COMPLETELY FAILED and SEIZED EVERY TIME it was tested, which resulted in a 0 psi value. No other oil has ever performed so badly when subjected to the Engineering torture testing that every oil is subjected to here. For better or worse, I can only post the test results the way they came out.
This oil was tested Spring 2019.
