In 1973, AMSOIL formulated and introduced the world's first synthetic 2-cycle oil recommended at the mix ratio of 100:1 for any two-cycle application. Since then, AMSOIL's core competencies in 2- and 4-cycle formulation have created benchmark synthetic lubricants that no other company can match. This industry-leading philosophy and technology extends to AMSOIL's Synthetic Two- and Four-Cycle Marine Oils, synthetic greases, synthetic marine gear lube, and specialty products
for your marine application. Regardless of the application you are looking for, whether it is for a high performance ski-boat, bass boat, offshore race boat, or for an auxiliary engine on a sailboat, AMSOIL has a designed product that is engineered specifically for your application. AMSOIL has two high performance synthetic NMMA-approved 4-cycle Marine Engine Oils and several synthetic 2-cycle oils designed for specific applications, including jet skis, EFI and DFI outboard motors, and racing applications.
