I'm mostly interested in ZPPD. I see that this oil has MB and Porsche approval, but it's API SM rating indicates it should have 939 ppm Zn and 770 ppm P.(1200ppm Zn and 994 ppm P is minimal for my car as per LN Engineering) It has ACEA A3/B4 rating I think.I really feel best with SE-SJ And Sl API rating due to the higher levels of Zn and P that's recommended for my Porsche 996. My parts supplier sells Total Quartz 9000 at a good price and free shipping that's why I would like to use it.
