How is that explained?
A: That bearing surface is still 100% garbage. The Snake-Oil decreased some wear, but if that "minor burnish" was on a connecting rod bearing, the bearing would be toast anyways.
B: This is a single test. Much like Lucas can "climb the gears" in the automotive store display, it's been given a test to show that specific property. This is an absolutely horrible thing for motor oil to do, yet Lucas advertises it. This test is designed to show their product performs better than the others. If the test was concluded, with a disclaimer that mentioned it also dissolved lead (your bearings), would you want it in your engine?
The big question is: Does your (any) engine need a higher performance lubricant than specified by the factory?
Let's take the BP mazda engine. The engine spec listed in my manual is "SL", IIRC.
SL, is obsoleted by SM (the pervious spec), and the current SN.
: SL is not longer available, SM is things like Rotella T6, and SN is basically any new stock oil. Rotella (and other) diesel oils cannot currently meet SN status, due to high additive levels, which in theory could shorten cat-converter life.
So with that in mind, ANY automotive engine oil you can buy today, is going to exceed what mazda engineers qualified as sufficient for the engine.
I see zero reason to run this product regardless. My drain plug is fully installed, with the oil pan properly filled.
