Racing formulations with elevated zinc content provide a safety net that allows components to survive the brutal conditions of track use. What Exactly is Zinc in Motor Oil? Zinc in motor oil is not a metallic additive but rather an organometallic compound known as zinc dialkyldithiophosphate.
Modern Engine Concerns and Zinc Additive Interaction
Oil Drain Intervals and Zinc Depletion It is important to recognize that zinc is a consumable additive. Performance and Racing Applications In the realm of motorsport and high-output street engines, high zinc motor oil is non-negotiable.
Compatibility with Modern Engine Designs While zinc is a hero for valvetrain protection, its interaction with catalytic converters necessitates careful consideration. The zinc additive ensures that the boundary lubrication phase does not result in catastrophic failure.
Modern Engine Concerns and Zinc Additive Compatibility
This molecule serves a dual purpose: it functions as an antioxidant to prevent oil breakdown and, more notably, as an anti-wear agent. Under the high pressure and sliding friction found within the valvetrain and bottom end, the zinc compound decomposes to form a durable chemical film on metal surfaces.
