D1 / Gen 3 Approved Oils Wear Ranking ?

Disagree lol or people wouldn't buy boutique. I have much faith in the top tier lines of High Performance Lubricants, Redline, Amsoil and others rocking the Grp 4 & 5 oils. @wwillson ran wayyyy longer than normal intervals on boutique and I'm sure there isn't a Dexos out there that comes close. You get what you pay for.
Bitterness remains long after the the sweet low price is forgotten.
Wwillson used HPL’s CK-4 version of their oil.
Also, HPL may use d1G3 add packs in certain product lines, but they do NOT meet or pay for dexos licensing, so it’s not really comparable.
Since dexos has both minimum and maximum levels on several additives, it is very likely that any oil that’s officially licensed will absolutely be statistically similar to all other licensed oils.
If you have between 3K to 6K on an oil, and you ran that oil consecutively, so its not the first run of it, and the wear metals of a used oil analysis shows 3 ppm or less per 1K miles, then it's a good oil for your application, according to Lake Speed, and he knows oil.
While this is true, no harm would come from using the suggested Quaker State product. It doesn’t really matter what oil you choose, as long as it carries the Dexos 3 1 designation.
IMHO, Dexos is just a marketing scam for a sub par car company to try and turn a profit somehow someway.
That logic is faulty. This thread concerns oil within the D 1 3 category. That other cars have different requirements is irrelevant, as is the wrong notion that Dexos is not good enough. Also, some, if not most, frozen pizzas are fantastic.
Disagree completely..
That’s not true…
The Noack being lower equals …. Better protection against piston deposits and sludge formation.
Porsche A40 and C30 clearly have tougher wear standards vs API SP.. . As does MB 229.5.
I have read those differences on the Afton handbook. It’s obvious there are differences and that Noack difference shows up in measurable performance results.
Maybe. First, you should know the OP has no car that requires D1 G3 as far as I can tell. Look at his thread history also. This is some weird spec fetishism. Second, I’m going to stand by the assertion that D1 G3 is not anything special. The Lubrizol tool, used correctly within a single manufacturer, shows it is inferior in most ways other than LSPI test to Dexos2. Since there are now Dexos2 (ACEA C3 based) oils with SN+ or SP additive packages, I see zero reason to go hunt for D1 G3 oils if your manual doesn’t call for it. If D1 G3 was so good, why does Cadillac eschew it for performance turbo DI engines? Every good gasoline engine from GM specs Dexos2/R. D1 G3 is an economy car engine oil spec and I’m sure cost sensitivity is a driver of this differentiation.
You’re right on the frozen pizza though. Unfair to good frozen pizza and exaggerates the difference to real pizza. Maybe fast casual food is a better comparison? Good, but no DexosR fine dining.
BMW in this video so I was going to say it’s Edy, but they pour LM and he wouldn't have that, so let’s say it’s TiGeo enjoying LM’s finest:

does not a fairly high percentage of engine wear occur at start up times vs running at normal temperature? ,the base oils relationship to a properly formulated additives package in the correct base oil require a license from the api,islac,dexos gen 3 and other engine manufactures specs mean anything? ,myself I look for the license and approvals & viscosity ,along with the lubricant reputations (brand) as a whole with the published astm specs, as low pour points, ccs ,flash point ,viscositys at various temps, noack & hths etc,,,, in a balanced formulation may meet and spec above the total requirments ,looking and learning this is like a jigsaw puzzle but do able on this site among some other reputable sources, you must be looking for the Transparency of understandable information of from manufacturer of the lubricant (providing they will say/publish) , as the application (engine type and driving habits and oci) are highly detrimental to this also. there is really no best oil for all........./.some really good ones, look hard.

Everyone knows your opinion - question is how many care.
I would love to see the test that shows that evaporation alone affects the physical performance of otherwise identical oils badly enough that it results in statistically dissimilar results between oils of the same approval/certification.
Could you please name two oils that have the same certs but dissimilar enough Noack results that would show this “obvious” difference in the measurable performance results? I’m genuinely interested, because AFAIK, the way those add packs are spec’d to meet certain approval all require a fairly specific group of base oils to mix them in without having to retest the entire blend for maintaining the approval.
That seems to group the performance into a fairly small window since the allowable base oils are chosen based on similar performance with that given add pack. But I’m all eyes for what you’ve got.

Funny video. I think that most D1 G3 oils are 0 W 20, and I suspect that is the current market dominant weight for passenger vehicles, so I am not sure that the thick stuff required for Corvettes is relevant. I will cede that these oils are not “Grey Poupon,” but they get the job done. I did not look into the archaeology of the original poster’s ideas, but sure that you have it right. As always, keeping OCIs as short as you can is far more impactful than choosing oil types. I am a proponent of doing what the manufacturer suggests, and as always, the general rule is that the car will fall apart around a nice running motor.
And what does all that have to do with wear?
In general PAO has somewhat higher wear than a Group I/II/III base stock. We are discussing wear here, not the advantages that a PAO base stock has.

Cars yes - but GM also puts allot of LT’s, vans, & SUV’s on the road with D1.3 in the owners manual - many of them doing hard duty …

As I said before - folks here get all weird over Dexos - but Dexron is treated differently … As a long term GM buyer (mine & Co.) - I’m confident with both …
Diesel vehicles were notorious for the motor outlasting the frame. I think many bought them simply for that reason especially in older Volvo and Trucks.
Are you saying D1 / Gen 3 oils are not approved for Cadillac , Corvette or Camero ?
