Why AMSOIL? | The introduction of the world’s first synthetic motor oil to meet American Petroleum Institute service requirements in 1972 set all-new standards for motor oil quality. AMSOIL synthetic motor oil outperformed conventional petroleum motor oils on all counts. It was clear from the start that this innovative product would play a major role in engine performance and engine life.
As the technology used in today’s marine applications has evolved, AMSOIL has remained ahead of the curve in performance and protection with products formulated to deliver clean engine performance and control harmful deposits, wear and rust. AMSOIL synthetic lubricants are engineered to protect your watercraft in all conditions so you can remain carefree and on the water longer.
