Is this the end of Zinc (ZDDP) in oil?

Zinc (also known as ZDDP, ZDTP or zinc dialkyldithiophosphate) is the most common lube oil additive. Patented in 1944, this molecular family has been used as low-cost, multifunctional additives in engine oils, transmission fluids, hydraulic fluids, gear oils, greases, and other lubricant applications. ZDDP’s' unique ability to act as an antiwear agent, an effective peroxide decomposer that protects against oxidation and corrosion and a mild extreme-pressure (EP) agent is what makes it the lubricant formulator’s best friend.

But lately, its popularity has been under attack. The rise of emissions regulations, exhaust after-treatment systems and new industrial lubrication requirements are driving formulators to alternative strategies. But finding replacements for a technology that has served the industry well for 80 years is complex, and end-users of lubricants will need to adapt their understanding of common lubricant degradation behaviours as formulations change.
