Holy cow you better grab a case of beer and not have any plans for the day if you plan on reading all that!!! I started and gave up after a half hour .
Apologies. That was never my intentions and the reason I mentioned to use word find in your browser on key words like "Brad".
So I did a little "cut-in-paste" on a few key issues he mentions in his blog about Brad-Penn by example;
(Begin blog research)*****
* FOR THE RECORD, I am NOT connected in any way to the Motor Oil or Aftermarket Additive Industry. I have absolutely no interest in what products people choose to use. So, I DO NOT promote any particular brand. I only share the results that come out of my Engineering tests, good or bad.
.
The Wear Protection reference categories are:
.
* Over 120,000 psi = FANTASTIC wear protection
.
* 105,000 to 120,000 psi = INCREDIBLE wear protection
.
* 90,000 to 105,000 psi = OUTSTANDING wear protection
.
* 75,000 to 90,000 psi = GOOD wear protection
.
* 60,000 to 75,000 psi = MODEST wear protection
.
* Below 60,000 psi = UNDESIRABLE wear protection
.
The HIGHER the psi value, the BETTER the Wear Protection.
.
Test result differences between oils of less than 10% are not significant, and oils within that range can be considered approximately equivalent.
.
IT’S WORTH REPEATING THAT SOME KEY POINTS TO KEEP IN MIND ABOUT THIS TESTING ARE:
.
The psi reference values above, ONLY APPLY TO MY TEST DATA, not to actual engine component loading. Here’s why:
The motor oil “Dynamic Wear Testing Under Load” I perform is WORST CASE torture testing. My test equipment is NOT intended to duplicate an engine’s internal components. On the contrary, the test equipment is specifically designed to generate severe loading, that will quickly cause an oil to reach its failure point, in order to determine what its capability limit it is. The test loading is severe enough, that the wear scar size that forms, based on an oil’s load carrying capability (the wear scar is what is measured), has stabilized at its final size by the conclusion of a 30 second load test. Procedure development testing showed that more time than that did not change the wear scar size. Every oil I test is brought to its failure point, that’s how it works. The difference in the failure points, is what we compare. My testing subjects the oil to far more severe loading than even the most wicked flat tappet race engine could ever generate.

25. “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

176. 10W30 Brad Penn, Penn Grade 1, partial synthetic = 71,206 psi
zinc = 1557 ppm
phos = 1651 ppm
moly = 3 ppm

213. 10W40 Brad Penn, Penn Grade 1, partial synthetic = 57,864 psi
zinc = TBD, but the bottle claims high zinc
phos = TBD
moly = TBD

This by Brad Penn:
“There is such a thing as too much ZDDP. ZDDP is surface aggressive, and too much can be a detriment. ZDDP fights for the surface, blocking other additive performance. Acids generated due to excessive ZDDP contact will “tie-up” detergents thus encouraging corrosive wear. ZDDP effectiveness plateaus, more does NOT translate into more protection. Only so much is utilized. We don’t need to saturate our oil with ZDDP.

I know I am probably reading to much into this testing. None the less, I am a big "Stick with what you know" type of person and that is Valvoline. The problem with their product is you either purchase conventional or synthetic with ZDDP. I am a huge fan of blends - which Brad-Penn provides - and Valvoline in this area is lacking. So, I researched all (Royal Purple, Brad-Penn, Amsoil, etc.) until I came across this blog. As scary as his research is, I like to think I can keep my 440 from wearing out before it's time.
BTW - He has done research on all the major brands of different motor oils and the main reason I swapped from Maxima to Valvoline (For now).
