AMSOIL 2-Cycle Oils provide second-to-none protection and performance in modern two-cycle equipment!

Two-cycle engines remain the workhorses in recreational equipment, including outboard motors, motorcycles, snowmobiles and personal watercraft, as well as in lawn and garden applications like lawn mowers and weed eaters. Design changes over recent years have included direct fuel injection engines, in which fuel is injected directly into the combustion chamber, and exhaust power valves, which improve combustion efficiency at varying RPM. These design changes have allowed two-cycle engine manufacturers to effectively reduce emissions, improve fuel efficiency and decrease oil consumption. Today's two-cycle motors of all types require specialized oil technology to deliver maximum engine protection,
dependable operation and long service life

As the leader in two-cycle oil technology, AMSOIL has performed extensive research in developing a new line of revolutionary, specialized oils called the "Fabulous Four." AMSOIL INTERCEPTOR Synthetic 2-Cycle Oil (AIT) was the first new oil to be introduced. It is primarily recommended as an injector oil or at a 50:1 mix ratio in carbureted, electronic fuel injected (EFI) and direct fuel injected (DFI) snowmobiles, personal watercraft, motorcycles and ATV's. Formulated with wax-free premium quality synthetic esters and a specialized additive package, INTERCEPTOR is designed to address the exhaust valve sticking problems associated with certain snowmobile models.

New AMSOIL HP Injector Synthetic 2-Cycle Oil (HPI), DOMINATOR Synthetic 2-Cycle Racing Oil (TDR) and Saber Professional (ATP) and Outboard (ATO) Synthetic 100:1 Pre-Mix 2-Cycle Oils complete the Fabulous Four lineup, replacing AMSOIL Synthetic 2-Cycle Injector Oil, Series 2000 Synthetic 2-Cycle Racing Oil and 100:1 Pre-Mix Synthetic 2-Cycle Oil, respectively. The application chart below ranks each oil's performance in common two-cycle applications.
