There are new additives including organic non-metallic adds that don't show up in uoa's. Do you really think that someone that uses super low zinc Eneos Sustina is going to have additional camshaft wear based on lower ZDDP levels? I think the oil formulators are smarter than that. OTOH, Mobil1 5W-20 does use more ZDDP than the 0W-20.

And where are you finding find M1 Racing?  I only see it on-line.

Hi bluesubie! Your stuff is always great reading here and on bitog. I just want to throw a couple of ideas at everyone.
First, Sustina has 800ppm of zinc in a form that is sulfur-free. This extends OCI capability and reduces corrosion from sulfuric acid. My conjecture is based on personal experience, UOAs and Eneos statements on their website.
Regarding M1, it's all about the base stocks. Esters and group 3 components are mixed to produce the best protection. Take M1 AFE vs M1 EP. They look the same. Obviously the base stocks are different.
I am excited about the new Pennzoil Platinum Ultra with PurePlus. It's GTL. For a long time, I have favored group3+ over even the high ester oils. This oil runs sooo clean. The new Ultra 0W20 will be my new favorite oil. The absence of high amounts of measurable additives and lack of low Noack numbers means nothing. In this case, it is indicative of an oil that is superior and doesn't even need additives. This oil was developed with GF6A/B in mind!
