The secret to prolonging your engine’s life isn’t just regular maintenance; it’s also about choosing the right products. Synthetic oils, like those from AMSOIL, are engineered to provide unmatched protection and performance. The pure, uniform molecular structure of synthetic oils means they work harder to protect your engine against wear, reduce oil breakdown, and facilitate quick cold starts.

AMSOIL 100% Synthetic CVT Fluid for Continuously Variable Automatic Transmissions

Remember, it’s not just your engine that benefits from high-quality, specialized fluids. The Continuously Variable Automatic Transmission in your Subaru* Legacy* also requires careful consideration. AMSOIL 100% Synthetic CVT Fluid is designed to meet the unique demands of CVTs, providing outstanding metal-to-metal frictional properties and enhancing the transmission’s response and longevity.
