Overview

It provides excellent heat resistance, allowing for doubled severe-service drain intervals with guaranteed AMSOIL protection. This fluid remains fluid in sub-zero temperatures and offers reserve protection during heavy use.

Tested by an independent lab, the transmission's valve body remained clean and virtually sludge-free after 180,000 severe-service miles, with clutch plates showing only trace discoloration and earning the highest rating for deterioration/wear. The formulation includes high concentrations of antioxidants for natural heat resistance and delivers extraordinary cold-flow properties. It also helps improve shift response, energy efficiency, and warm-up times.

It is formulated to withstand extreme heat, enabling users to confidently double their vehicle manufacturer's recommended severe-service drain interval while maintaining guaranteed AMSOIL protection. This synthetic fluid also boasts exceptional cold-flow properties, remaining fluid in sub-zero temperatures and contributing to improved shift response, energy efficiency, and faster warm-up times. Extensive testing by an independent laboratory demonstrated the fluid's superior protection. Following 180,000 miles of severe-service operation, the transmission's valve body was found to be clean and virtually sludge-free. Clutch plates exhibited only trace discoloration, achieving the highest possible rating for deterioration and wear, underscoring the fluid's robust performance under demanding conditions. The fluid's formulation includes a high concentration of antioxidants, making it inherently resistant to thermal breakdown, while its advanced components enhance overall transmission longevity and efficiency. This product is recommended for GM, Ford, and Toyota transmissions where a lighter viscosity oil is required. It is also backward compatible and can replace DEXRON III fluids in older GM automatic transmissions, while also meeting DEXRON VI specifications.
