We've posted a new banner from Lubrizol that draws attention to their new HyperZDP additive. Click on the banner or here , then click on the orange "click here to learn more" in the center of their page.
It's been out for awhile now. I think this is what Valvoline is touting in their advertisement. Seq IIIG phosphorus retention test. Looks like a 10% increase max. for retention in the IIIG. It's a low volatile ZDP.
