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.
