Why use Zink In your Oil?

November 29, 2010 by Tim

Passenger car and truck oils are formulated to reduce emissions and provide longer drain intervals. This has been done by increasing detergents and reducing anti-wear additives, but your race engine operating under high load and high RPM conditions needs high amounts of anti-wear additives (Zinc and Moly) to create a sacrificial additive coating that prevents metal to metal contact in your engine.

Modern Engine Set-up:
Decreased anti-wear (i.e. Zinc)
and more detergents:

• Catalytic Converters
• Low RPM
• Overhead Cams
• Extended drain intervals

Race Engine Set-up:
Need more anti-wear (i.e. Zinc)
and less detergents:

• High RPM
• Higher Torque
• Flat tappet cams and push rods
• Shorter Drain intervals
• High RPM
• Higher Torque
• Flat tappet cams and push rods
• Shorter Drain intervals

Use a Compatible Products to Avoid Additive Clash
Properly protecting the engine from excessive wear during initial start-up and break-in is critical to the long-term life and performance of the engine. By utilizing matched additive chemistries in the products we use to assemble, break-in and operate our engines, we eliminate the risk of additive clash.

Typical Break-In Procedure:
Additive Clash can occur when switching between products with different additive chemistries putting the engine at risk.
