Royal Purple® synthetic Motor Oil is a tough, long life, high performance oil that delivers superior protection and enhanced performance to gasoline and diesel engines. It gains its performance advantages from a blend of synthetic oils plus Royal Purple's proprietary, synthetic Synerlec® additive technology. This technology is the force behind Royal Purple motorsports' exceptional performance.

All Royal Purple products have super-tough film strength, outstanding viscosity stability, a very low coefficient of friction and tenacious adherence to metal surfaces. This enable engines to produce more horsepower and torque with less wear over much greater periods of time. Royal Purple lubricants have the ability to reduce heat from friction as a result of incredible film strength, thereby increasing part life. Royal Purple's motor oils are API certified and will not void new car warranties. Plus they are compatible with other mineral and synthetic motor oils.

Purple Ice® is a high performance, synthetic, radiator coolant additive for both gasoline and diesel engines. It is formulated to reduce the surface tension of the coolant, which improves heat transfer through the cooling system while providing additional protection against rust, corrosion and erosion.

Purple Ice® prevents the formation of scale deposits in the radiator for optimum coolant flow and lubricates the seals of the water pump. It is ideal for use in straight water racing applications or in antifreeze / water mixtures.

Purple Ice® is compatible with traditional ethylene glycol antifreeze (green) and GM Dex-Cool® antifreeze coolants. Purple Ice should not be used in new radiators until anti-freeze has been cycled through the
