Who is ZPlus, LLC?
ZPlus, LLC is a company formed by classic car enthusiasts to meet the needs of classic car aficionados. We have seen that the automotive industry in general is changing in response to the environmental and financial pressures of today, with little concern for the classic car industry. We are engineers and automotive technicians by trade, and bring many years of problem solving experience to the task of keeping our classic cars operational and running better than new. We hope one of the solutions we have designed for our own use will meet your needs as well. We have developed ZDDPlus™ to address the need of classic car owners for oil that will meet the specifications of the original oil for which their engines were designed.
Why do we need ZDDPlus™?
As part of an effort to reduce vehicle emissions, the U.S. EPA offers vehicle manufacturers “credits” for early implementation as well as penalties for violation of emission reduction standards. The EPA’s program called for
100,000-mile catalytic converter life by 2004, 120,000 miles by 2007, and 150,000 miles by 2009. To achieve these goals, automotive manufacturers have pressured their oil suppliers to reduce or remove substances from
motor oils that would shorten the service life, including the proven antiwear additive ZDDP (zinc dialkyldithiophosphate). Zinc and phosphorus from the ZDDP can be present in small amounts in the exhaust gas
of an engine depending on the amount of oil which is consumed in combustion. Phosphorus in particular has been singled out as an element which can coat the catalyst reducing the amount of catalyst exposed to the exhaust gases and ultimately increasing emissions at the tailpipe. As a result of the EPA mandate, the phosphorus level in engine oils (from the ZDDP) has been declining since the introduction of SJ oils in 1996, roughly coinciding with the implementation of OBD-II.

What Is ZDDP?
To quote one 2005 research study: “The most common antiwear additives used in engines are zinc dialkyldithiophosphates (ZDDPs), which have the chemical formula Zn[S2P(OR)2]2, where R is an alkyl group.
ZDDPs have successfully been used for over 60 years, and to date no superior antiwear additive has been developed for use on steel.
ZDDP has an excellent track record at protecting the sliding metal-to-metal cam lifter interface. Historically, ZDDP has been added to oils in amounts resulting in approximately 0.15% phosphorus and 0.18% zinc. ZDDP protects by creating a film on cams and flat lifter contact points in response to the extreme pressure and heat at the contact point. The film of zinc and phosphorus so formed provides a sacrificial wear surface protecting the base metal of the cam and lifter from wear. In the course of normal service, this conversion of ZDDP to elemental zinc and phosphorus depletes the ZDDP level in the oil.
