The SM version has the reduced Zinc.
"Many Porsche repair shops have acknowledged that these newest SM and CJ-4 motor oils are not sufficient for protecting any Porsche engine"

John - Thanks for the link to that article. A couple of basic questions about this paragraph: "Porsche’s recommendation in hand, our initial analysis from 2005 and 2006 found that then recent SH/SJ/SL formulations of Mobil lubricants tested, including Mobil 1, have had similar 0.12-0.14% Zn and P content, which we thought was a good thing, but looking closer, Mobil 1 0w40 had somewhat less Zn and P, at 0.10%. Current SM formulations are at the 0.10% level or less. This confirms the industry wide trend of the reduction of Zn and P from motor oils, with the eventual reduction to 0.06-0.08% or even worse, the elimination of these additives, which are essential to an aircooled Porsche engine's longevity. "
Is the Mobil 1 SM formulation mentioned in the article the Extended Performanc version with the gold top? Is the "new" silver top Mobil 1 product the SH/SJ/SL formulation?
It's time for an oil change for my '95 coupe and '96 TT, so thanks for the timely link.
