What motor oils had the 0.12% levels of zinc and phosphorus recommended?

The current API standard is SM, and calls for 0.06-0.08% Zn and P. The new CJ-4 standard which supercedes CI-4 calls for no more than 0.1% P.

Some of these reformulations have new zinc-free anti-wear additives, but we still think a target of 0.12% is ideal for Zn and P levels as documented by the 1977 SAE Journal paper titled

"Cam and Lifter Wear as Affected by Engine Oil ZDP Concentration and Type", which evaluated the performance of these oils in various fleets around the country over the span of many years.
