Zinc Oil Additive
Description

High-Zinc & Phosphorus Diesel Oil Additive – Ideal for Flat Tappet Cams


Boost the protective power of your diesel oil with this ZDDP-rich additive, formulated to elevate zinc and phosphorus levels to approximately 1,500–1,650 ppm—the optimal range for flat tappet cams. Whether you’re running a competition engine or breaking in a daily driver, this additive provides an extra layer of wear protection and enhanced lubrication.

Key Benefits

  • Increased Zinc & Phosphorus: Precisely raises ZDDP levels for improved cam and lifter longevity.
  • Perfect for Flat Tappet Engines: Minimizes metal-on-metal contact, reducing the risk of premature wear.
  • Competition & Break-In: Use every oil change in race applications or at least during break-in for daily drivers.
  • Compatible with Most Diesel Oils: Mixes seamlessly with your preferred high-quality diesel lubricants.

Safeguard your engine’s moving parts and extend its service life by adding our High-Zinc & Phosphorus Diesel Oil Additive to your maintenance routine.
