The pretty tight window of specs on d1 oils plus the presence of a paid license pretty much guarantees any slight differences you may see will not be statistically significant over the long term; I.e. they’re all the same.Is there reliable information to know where D1 / Gen 3 approved oils rank regarding wear protection ?
Nor would it be useful.There is no such thing as a wear ranking like that.
Or accurateNor would it be useful.
It can’t be used to evaluate between different oil specifications. The Lubrizol site has explicit wording about that…i can across this a week ago , its an interactive tool ,to compare the traits of different aproval ratings

Hence the reason for “specifications” not “good ideas” or “we think this should do it”.It seems this test isn't very stringent, and most oils will perform similarly.
As has already been noted there are limitations of that tool. Plus they aren’t graphs of absolute numbers anyway. They are areas of emphasis for that particular approval or license.i can across this a week ago , its an interactive tool ,to compare the traits of different aproval ratings

It does seem like Lubrizol at least makes an effort to make the charts comparable to one another. It's just that it's not always possible to know whether one test is more stringent than another if it uses a completely different engine and test procedure. It's a judgement call, hence the disclaimer.It can’t be used to evaluate between different oil specifications. The Lubrizol site has explicit wording about that…
How would the claim new and improved rank?You won't find rankings published, but many companies make specific claims for how well their oil performs in the Sequence IVA or IVB valvetrain wear tests used for the API and Dexos standards.
Castrol Edge claims 6x better wear protection than the minimum required in the IVA test, which I suppose means 83% less wear. Amsoil SS claims 77% less wear. Pennzoil Platinum claims that "No other leading motor oil performs better" in the IVA test, which would make it at least as good as the Castrol Edge (unless Pennzoil decided that it doesn't qualify as a leading motor oil).
I've seen some results from independent IVA tests in studies, and those oils also produced around 80% less than the allowable wear. It seems this test isn't very stringent, and most oils will perform similarly.

4 ball bearing wear test ?There is no such thing as a wear ranking like that.
4 ball bearing wear test ?
Wear ranking? I swear if someone even talks about 540rat, I'm going to blow a ****ing gasket
Sure, but those numbers don’t have any relative values to compare with the Lubrizol tool. That’s part of the approval/certification requirements.Interestingly though…
There are definitive numbers there which do prove beyond any doubt that Porsche C30 , C20, A40 and MB 229.5 are much harder to hit versus regular API standards aka numbers. Like Noack being less than 10 percent for MB and Porsche vs 15 percent for API .
Yes !! … Just left to go by Quaker State Full Synthetic 5W30 , 540 Rat’s highest rated !!Please don't be referring to 540rat lol
