Signature Series Fuel-Efficient Synthetic ATF

The AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is engineered for vehicles that experience severe service, such as heavy towing, extreme temperatures, and difficult terrain. This fluid offers significant protection against thermal breakdown, thanks to its formulation with high concentrations of antioxidants. It also boasts extraordinary cold-flow properties, ensuring it remains fluid even in sub-zero temperatures. These characteristics contribute to improved shift response, enhanced energy efficiency, and faster warm-up times, optimizing overall transmission performance. Independent laboratory testing, specifically the ABOT test based on total acid number (TAN), demonstrated the fluid's ability to maintain transmission cleanliness and virtually sludge-free operation after 180,000 severe-service miles. In this test, clutch plates showed only trace discoloration, earning the highest possible rating of "good" for deterioration and wear, highlighting the fluid's durability and protective capabilities.
