Although we can group many uoa's together, it won't come close to an industry certification because there are differences in how hard the cars were driven, modifications, and when the oil was changed. Certifications are achieved through specific testing criteria.
Alot of these less abundant oils with great street credibility may be robust, but I am having a hard time being convinced that they are better than a highly certified Mobil 1 5w30 or 10w30 (or penzoil platinum). What are these assumptions/facts based upon? If it was based on uoanalysis, how many uoa's was enough to convince you?

This isn't a science, additive testing is the main tool used on the internet. Most UOA are worthless unless you see triple digits in iron or copper then its too late. The UOA is used to help cheapstakes extend their oil change interval more than anything. and last these UOA's don't measure a fraction of the new complex molcules in the oils, kind of like analyzing a burnt to ashes eastern dinner.

I'm curious what some of the local reviews are about this. The amount of moly and zinc has me interested. A BITOG VOA has the VI of this pretty high. It isn't as high as Sustina, but pretty close.

I'm using the high moly Mazda 0-20 and love it. I did cheat by adding a half quart of 0w-30 mobile one racing oil, but the engine doesn't bog at 2krpm and its smooth throughout when cold but still takes forever to warm up. It even jump started from a completely dead battery with a tiny battery jump start pack. And the engine is quiet at idle easy to damage the flywheel by double starting.
