I assume you are alluding to myself, a few others and
@High Performance Lubricants.
It's actually quite simple and I've explained this before, but perhaps you missed that post?
Approvals are foundational. That is, they establish the minimum level of performance for a given product. The Euro approvals are, generally, more stringent than the API and non-Euro manufacturers, so they make a good baseline.
So, if you want a guaranteed level of performance that goes above and beyond the basic API stuff, it's a good idea to start with a slate of Euro approvals. I personally prefer the Full-SAPS ones, LL-01, MB 229.5, Porsche A40...etc, these are typically all based on A3/B4 with further refinements.
Now, my use of HPL's products has nothing to do with them being a site sponsor but rather with how and who, develops their products, I'd like to get that out of the way first and foremost. Yes, I appreciate Dave's candor and transparency with the board, but that wasn't the reason I chose to make the leap.
If a company buys an approved additive package from say Infineum (or Lubrizol, Oronite...etc) that meets 229.3/229.5, A40, VW 502 00/505 00, uses it with a premium slate of base oils, and then has one of the foremost experts on lubrication and tribology tweak that additive package, improving its performance, for me, personally, even though the product is not formally approved, it was developed using an additive package that is, and the person making the tweaks, his expertise is recognized broadly by everyone in the industry, so I'm comfortable with it not showing up on the BEVO list because I KNOW that it was capable of being there if submitted, as Dr. Rudnick's modifications aren't going to make it perform worse.
There's a gaping chasm between that approach, and something developed "on the cheap" that's "recommended for" Euro applications but only has API SN for example and a Noack that precludes it from being 229.5 regardless of those "recommendations".
Now, perhaps you, personally, aren't comfortable with that chain of logic as I've constructed it, and that's perfectly fine, but this isn't something that has appeared from a vacuum or out of blind faith in a company because they support this forum. It's a very methodical approach being taken here with no risk, because the foundational components ARE officially approved, and then massaged/fortified to improve performance further beyond where it is economical for traditional vendors by somebody whose expertise is indisputable.
