Do not chose an oil from a website that is nothing but a huge dumpster fire. That guy is a complete idiot and what he does there is rank ignorance.
An oil taste test by 12-year olds would yield an equally valid ranking.
D1 / Gen 3 Approved Oils Wear Ranking ?

Not relevant for engine oils.
I believe that in a well designed engine such as the Duratecs in my Fords, the Skyactiv in our Mazda, the 1ZZFE in my Corolla etc...that using any oil that meets the recommended spec. (including brands such as Supertech, Kirkland, STP etc...(store brands) changed at decent intervals (5 to 7K depending on usage....short trip vs. highway miles) will allow the engine to last hundreds of thousands of miles.
Having said that....I believe that those who extend their OCIs to 10K and beyond would be better served using oils such as Mobil1 EP, Castrol gold Edge EP, HPL, Amsoil etc...Since I'm not going to do extended OCIs....I'm satisfied that any D1G2 or D1G3 oil is going to
suit my needs fine and serve me well.

Most oils made today do a great job at keeping engine wear at a reasonably low level. I think the greater concern is choosing an oil that keeps the engine cleaner in the long run.
I believe within a G1/Gen 3 or SP specification there will be oils which exceed the minimum requirements for wear . Marketing terms will be used by stating “exceeds wear requirements by 25% , 30% , etc” . I use M1 5W30 EP so I’m not concerned that my engine will wear out . It would just be nice to know how G1 / Gen 3 , SP oils really perform with respect to wear levels .
Okay I don’t think you’re really grasping this concept mechanically.
Wear levels compared to… what? And how would you compare them?
Wear levels compared to other oils in the same category such as D1 /Gen 3 5W30 oils in similar engines . *Perhaps the only way to easily test is run three 5K mile OCI’s using three different D1/Gen. 3 rated 5W30 oils and then have UOA’s tested at Blackstone to compare wear levels ? Does anyone else care about wear levels of their chosen engine oil as compared to other engine oils of a like comparison category (D1 / Gen 3) ?
You are miles from what would be required to actually compare different motor oils in regards to wear. An uncontrolled $30 spectrographic analysis is wholly inadequate for this purpose. Sequence VIII tests that include ASTM D6709 would appropriate.
But wear is really a minor concern in any modern fully formulated oil. All oils have good wear protection, those "35% better" statements are mostly meaningless, a 35% change in an already small number has virtually no relation to anything that would be noticed. @Patman is correct in his statement above.
If all blenders and manufacturers had to do to obtain an API license or a manufacturer approval was to send a sample to Blackstone (and then have Bitog members analyze the results) then they would be all over that.

Even in a perfect world if you could figure out which oils might show lower engine wear and rank them accordingly, I would be willing to bet that the difference between the major brands would be too close to call. In other words the lowest ranking oil might get you 400,000 miles out of your engine and the highest ranking one would be 410,000 miles. But we’re never going to get that kind of data.
And yes we do care about engine wear, but at the same time how many people on BITOG have ever experienced an engine wearing out on them?
Do you have a GM engine that recommends using d1G3 oils, or is this just a random question?
M1 EP meets or exceeds numerous API specifications and also multiple manufacturer requirements. It’s a good oil from a major supplier. As long as it satisfies your vehicle’s recommendations, use it without worry that you’re “missing out” on anything.

I bet the wear between all those is very similar.At the bottom after boutique oils and Frankenbrews done by BITOG members
540 is a joke. Just saying.
Moly is Moly.What about D1G3 with real moly?
And to amplify my earlier post, yes “moly” as in molybdenum is the same atom regardless of the compound. That’s what shows up on the spectrographic analysis. But the additive compounds are not the same.
