Signature Series 0W-20 Synthetic Motor Oil

The Amsoil Signature Series 0W-20 is a premium 100% synthetic motor oil engineered to provide superior lubrication and protection in modern automotive gasoline engines. It is formulated to withstand the demands of higher horsepower, increased heat, and complex emissions control systems, outperforming conventional and other synthetic motor oils. This synthetic formulation offers significant benefits, including extended drain intervals of up to 25,000 miles or one year in normal service (15,000 miles in severe service). It maximizes fuel economy by reducing internal friction due to its uniform molecular structure and anti-friction additives. The oil provides exceptional wear protection through excellent viscosity film strength and robust anti-wear additives, contributing to extended engine life. Furthermore, its low volatility rate helps control oil consumption and emissions, while its resistance to thermal breakdown and wax-free formulation ensures fluidity in extreme cold for easier starting and reduced bearing wear. Amsoil Signature Series 0W-20 meets or exceeds several key industry specifications, including API SP (Resource Conserving), GM dexos1 Gen 2 (supersedes 6094M), ACEA A5/B5, Ford WSS-M2C947-B1, and Chrysler MS-6395. It also offers advantages such as 75% more protection against horsepower loss and wear compared to leading competitors and 50% more cleaning power. Extended drain intervals are recommended for unmodified, mechanically sound gasoline-fueled vehicles. Engines operating under modified conditions (e.g., performance computer chips, non-OEM approved exhaust, fuel, or air induction systems) are excluded from these extended recommendations. It is crucial to ensure engines are in good working condition, without leaks or excessive oil consumption, before installing Amsoil synthetic oils. Mixing Amsoil with other oils is not recommended for maintaining performance benefits and extended drain intervals.
