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

Vice President Alan Amatuzio About
AMSOIL's 2-Cycle Product Development

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.

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. The application chart below ranks each oil's performance in common two-cycle applications:

AMSOIL HP Marine Synthetic High Performance 2-Cycle Engine Oil HPM

New!  AMSOIL HP Marine Synthetic 2-Stroke Oil

AMSOIL HP Marine Synthetic 2Cycle Oil The HighPerformance Marine 2Stroke Oil   
AMSOIL HP Marine is formulated with MAXDOSE™, a system of advanced additives for "super-clean" operation. It helps prevent deposits that lead to poor performance. In field testing, HP Marine inhibited ring deposits that can cause ring sticking and ring jacking (carbon build-up behind the ring, forcing it outward), a phenomenon that occurs in modern DFI outboard motors. It also virtually eliminated exhaust port deposits for reliable, efficient operation. HP Marine™ is recommended for use in all two-cycle outboard motors including, but not limited to, Johnson® and Evinrude® FICHT® & E-TEC™ (replaces XD100™ 2-Cycle Oil); Mercury® EFI & Optimax®; Yamaha®; Nissan® and Tohatsu® TLDI®; Suzuki®; Mariner® and Force®. Use as injection oil or as 50:1 pre-mix where NMMA TC-W3 or API TC oils are specified.

AMSOIL Quickshot AQS

AMSOIL Quickshot®

AMSOIL Quickshot Solves Fuel Problems The premium fuel additive to thoroughly clean and restore peak performance in small engine and powersports equipment fuel systems. Degraded fuel presents a major maintenance issue in small engines and powersports equipment. AMSOIL Quickshot’s revolutionary technology focuses on three major fuel-related issues plaguing small engines and powersports equipment: ethanol, water and dirty pump gas. They can form varnish, gum and insoluble debris that clog carburetors, fuel injectors and fuel filters. Carbon buildup can form on the tops of pistons that leads to pre-ignition, rough idling and poor throttle response. Fuel-related problems are only expected to intensify in the coming years as the ethanol content in pump gasoline continues to increase. AMSOIL Quickshot also stabilizes fuel between uses and during short-term storage periods.

AMSOIL Engine Fogging Oil

AMSOIL Engine Fogging Oil

AMSOIL Engine Fogging OilTwo- and four-stroke recreational vehicles, hand held power equipment, small engines, construction and farm equipment are commonly operated seasonally or infrequently, then stored for long periods of time. During these periods of inactivity, and as a result of fluctuations in ambient temperatures, water vapor can form condensate within the engine. Long periods of storage can also dry out cylinders, often resulting in permanent damage when the equipment is taken out of storage and dry started. AMSOIL Engine Fogging Oil offers superior film retention, providing long-term protection against corrosion and dry starts, extending engine life and reducing operating expenses. Its aerosol spray formulation offers easy and clean applications, while reaching more components and offering better distribution than straight motor oil. AMSOIL Fogging Oil protects all equipment during the off-season so it runs when you need it!

AMSOIL Gasoline Stabilizer AST

AMSOIL Gasoline Stabilizer

AMSOIL Gasoline Stabilizer fights fuel deteriorationFights fuel deterioration! Gasoline is not formulated for long-term storage and can start to degrade in as little as 60 days, leading to varnish and sludge deposits that clog injectors, fuel lines and carburetors, stick floats and cause poor engine performance, starting problems, increased maintenance expenses and decreased equipment life. AMSOIL Gasoline Stabilizer is suitable for gasoline or diesel fuel, and keeps fuel from deteriorating during storage allowing easier start-ups. It resists the formation of varnish and gum in fuel systems and storage tanks. Ideal for all two- and four-cycle engines, including motorcycles, snowmobiles, boats, ATVs, edgers, tillers, mowers, cars, trucks, snow blowers, chain saws, generators, farm and construction equipment. Mixes 1 oz. to 2.5 gallons of fuel.
