Product Application Specification

• SAE 15W-50
• API CK-4 (and prior)

Product Description
It is specifically engineered to deliver the most important benefits for high-horsepower and turbocharged competition diesel engines, including superior bearing protection and robust durability that withstands extreme pressures and temperatures.

Whether competing in sled pulls, drag races or dyno challenges, competitors using Freedom Series Synthetic Racing Oil enjoy confidence and security in knowing that their powerful diesel engines are receiving maximum protection and achieving maximum performance

Wear Protection
Racing and high-performance diesel engines are modified to deliver maximum horsepower and torque. Their powerful designs create shearing forces that can cause oils to lose viscosity, leaving bearings, pistons and other components vulnerable to wear and failure. Freedom Series 15W-50 Synthetic Racing Oil effectively withstands high cylinder pressures and protects against wear. It is heavily fortified with zinc and phosphorus anti-wear additives to provide additional protection against scuffing and wear in severe conditions.

Viscosity Control
High-horsepower diesel engines push a lot of fuel, leading to fuel dilution. Fuel reduces the oil’s viscosity. As the oil becomes thinner, it compromises the lubrication of critical components, increasing wear. Freedom Series Synthetic Racing Oil’s robust formulation helps offset the damaging effects of fuel dilution by maintaining its protective viscosity longer.

Withstands Turbocharger Heat
Over time, turbos can suffer reduced performance or catastrophic failure. Freedom Series Synthetic Racing Oil is designed with an extremely durable 15W-50 synthetic formulation that contains maximum levels of oxidation-inhibitor additives to resist harmful oxidation and provide exceptional resistance to deposit formation, preserving turbocharger performance and life.

COMPATIBILITY
Freedom Series 15W-50 Synthetic Racing Oil is compatible with other conventional and synthetic engine oils. Mixing AMSOIL racing oil with other oils, however, will reduce its performance benefits.

Aftermarket oil additives are not recommended for use with Freedom Series 15W-50 Synthetic Racing Oil.

SERVICE LIFE
For racing and competition use, the vehicle owner is responsible for determining the appropriate service interval.
