As a jet fighter squadron commander LIEUTENANT COLONEL ALBERT J. AMATUZIO had ample opportunity to witness synthetic lubricants in action. These oils are used exclusively in jet engines because of three extraordinary performance characteristics: an ability to reduce friction and wear on engine components, an ability to function dependably at severe temperature extremes and an ability to withstand rigorous and lengthy engine operation without chemical breakdown.
Recognizing that these same benefits would prove invaluable in combustion engines, Al Amatuzio formulated the first synthetic motor oil in the world to meet API service requirements for automobile engines. The new lubricant performed like no other before it. When the first can of AMSOIL 10W-40 appeared on the market in 1972, it signaled the birth of an entire industry. AMSOIL synthetic lubricants have expanded the boundaries of lubrication science and redefined the performance possibilities of modern machinery and engines.
AMSOIL Signature Series Synthetic Motor Oil delivers extraordinary lubrication in all types of automotive gasoline engines. By combining industry-premier synthetic technology with AMSOIL premium additives, Signature Series Synthetic Motor Oil exceeds the higher performance demands of modern engines. It withstands the stress of higher horsepower, higher heat and complicated emissions control systems. Signature Series Synthetic Motor Oil is engineered to outperform competitive conventional and synthetic motor oils. It delivers long-lasting performance and protection.
AMSOIL Signature Series Synthetic Motor Oil can extend drain intervals far beyond those recommended for conventional oils. Its unique synthetic formulation and long-drain additive system are inherently stable to resist oxidation and neutralize acids over longer periods. Signature Series Synthetic Motor Oil is designed to deliver the best possible engine protection, cleanliness and performance over extended drain intervals. It reduces vehicle maintenance and waste oil disposal costs.
