AMSOIL Synthetic 2-Cycle Oils

Benchmark Products in the Industry

Two-cycle engines are workhorses in powersports, recreational equipment and in power equipment. 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 synthetic oil technology to deliver maximum engine protection, dependable operation and long service life.

No one else matches AMSOIL for performance, cost and protection in 2-cycle motors.

AMSOIL Interceptor® 100% 2-Stroke Oil

A specialized oil for today’s specialized engines

Two-stroke snowmobiles are meant to be ridden hard. However, aggressive all-day riding and repeatedly running your machine at wide-open throttle takes its toll on the engine. INTERCEPTOR Synthetic 2-Stroke Oil is engineered to be pushed as hard as the sleds it protects for maximum performance in all makes of two- stroke snowmobiles, including Ski-Doo,* Polaris* and Arctic Cat.* It is compatible with nearly all other two-stroke oils and its low-smoke, low- odor properties help ensure riders won’t get “smoked out.”

AMSOIL Interceptor Synthetic High Performance 2-Cycle Oil

  • Excellent for all two-stroke snowmobiles 
  • Prevents piston ring & exhaust power valve sticking 
  • Exceptional cold-temperature fluidity (-63°F [-53ºC] pour point) 
  • Outstanding performance in DFI engines 
  • Protects against wear 
  • Low smoke and odor 
  • Helps prevent plug fouling 

AMSOIL 100% Synthetic 2-Stroke Injector Oil

Provides quality and affordability for cost-conscious enthusiasts who want the benefits of synthetic two-stroke oil

Strenuous conditions define the normal operating environments of snowmobiles and boats. Without the right lubrication, two-stroke snowmobile engines and outboard motors run hotter, accumulate deposits and suffer a reduction in performance. AMSOIL Synthetic 2-Stroke Injector Oil offers the convenience of one formula for the tough conditions of all two- stroke recreational equipment. It is tested and proven to minimize wear and deposits that can damage internal components. AMSOIL Synthetic 2-Stroke Injector Oil provides quality and affordability for cost-conscious enthusiasts who want the benefits of synthetic two-stroke oil. Use in all two-stroke outboards (for Evinrude* factory-lean setting, use AMSOIL HP Marine® Synthetic 2-Stroke Oil), snowmobiles and other recreational equipment where TC-W3 or API-TC oils are specified.

AMSOIL Synthetic 2-Stroke Injector Oil

  • Ideal for outboard motors and snowmobiles 
  • Protects against rust and wear 
  • Controls deposits 
  • -60°F (-51°C) pour point 

AMSOIL 100% Synthetic 2-Cycle Marine Oils

High-Performance Marine 2-Stroke Oils

AMSOIL HP Marine® 100% Synthetic 2-Stroke Oil

High-quality oil is critical for maximum performance in modern two- stroke marine motors. Direct fuel injection (DFI) improves combustion efficiency, delivering the extra power boaters want, while leaner gas-to- oil ratios provide the reduced exhaust emissions the government mandates. The leaner ratio leaves less oil to lubricate and protect these hotter, more powerful motors, which invites deposits and wear that threaten engine performance and life. HP Marine is proven to excel in these harsh conditions. It controls performance-robbing friction, heat and wear, yet produces low smoke and has low aquatic toxicity properties. It’s an oil as advanced as the engines it protects.

AMSOIL HP Marine Synthetic High Performance 2-Cycle Engine Oil

  • Excellent for Evinrude* E-TEC* factory-lean setting
  • Helps prevent deposits
  • Protects against wear
  • Low smoke
  • Protects against rust
  • Low aquatic toxicity
  • Superior performance as an injection oil or at 50:1 pre-mix 

AMSOIL 100:1 Pre-Mix 100% Synthetic 2-Stroke Outboard Oil

Performance-Engineered for Outboards

AMSOIL Synthetic 2-Stroke Outboard Oil is engineered with low- temperature dispersants that reduce varnish and carbon deposits to help eliminate plug fouling and promote rapid throttle response in water-cooled outboard motors. Its environmentally friendly low-smoke, low-odor, low-toxicity properties produce fewer emissions at 100:1 mix ratios than other oils mixed at 50:1.

AMSOIL Outboard 100:1 Pre-Mix Synthetic 2-Stroke Oil

• Protects two-stroke outboards at 100:1 mix ratios. • Prevents plug fouling and ring sticking. • Improves idling and throttle response. • Minimizes smoke and emissions.

SABER Professional eliminates the problems that plague handheld two-stroke equipment using other oils, including hard starting, rough-running, power loss and shortened service life. We tested SABER Professional at a 100:1 mix ratio compared to other two-stroke oils at 50:1,and the results are clear: SABER Professional dominated the competition in every area of performance. Even when using half as much oil, SABER Professional does a better job fighting carbon deposits that rob engines of power and reduce their service live. It helps landscapers, contractors and other professionals work more efficiently and cut costs.
