Interceptor Synthetic 2-Stroke Oil


2-cycle injector oil snowmobile and jet skiRegarded as ‘The Main’ Snowmobile oil which also encompases personal water craft and other 2-stroke engines with powervalves. Individuals using OEM brands are really missing out on performance and the resulting reduction of costly maintenance.

2-stroke snowmobiles are meant to be ridden hard. Repeatedly pushing a machine to wide-open throttle during all-day, aggressive riding, however, takes its toll on the engine. INTERCEPTOR Synthetic 2-Stroke Oil is specifically designed for maximum performance in all makes of two-stroke snowmobiles, including Ski-Doo®, Polaris® and Arctic Cat®, helping enthusiasts spend more time riding and less performing maintenance. It is compatible with nearly all other two-stroke oils, while its low-smoke, low-odor properties help ensure riders won’t be “smoked out.” INTERCEPTOR is engineered to be pushed as hard as the sleds it protects.

Anti-Scuff/Anti-Wear for 2-stroke snowmobiles 

Snowmobile 2-stroke engines have evolved to run on leaner gas-to-oil mixtures, increasing harmful friction and heat. INTERCEPTOR’s synthetic formulation incorporates highmolecular-weight components with high flash points that resist burn-off. As a result, a greater amount of oil survives the combustion process to provide lubrication and protection. Its excellent lubricity and film strength inhibit metal-to-metal contact. In extreme dynamometer testing, INTERCEPTOR’s anti-scuff/anti-wear formula completely prevented piston skirt scuffing.

Excellent Deposit Control

INTERCEPTOR naturally resists harmful deposits due to its thermally stable synthetic formulation. It is additionally fortified with high-temperature detergency and dispersancy additives that provide excellent engine cleanliness. In extreme dynamometer testing, INTERCEPTOR completely prevented piston ring and exhaust power valve sticking for maximum performance. It also limited piston, combustion chamber and spark plug deposits for reliable operation.

Proven in Extreme Dynamometer Test on Rotax® E-TEC® Engine

INTERCEPTOR 2-stroke was installed in a 2012 BRP® Ski-Doo® Renegade X snowmobile equipped with a Rotax E-TEC 800R engine. Following 50 hours of severe-duty engine dynamometer testing designed to simulate a full season of real-world conditions, the engine was disassembled and rated for deposits, wear and other distress by an ASTM calibrated rater. Each component earned a merit rating on a scale of 0 to 10 (with 10 representing no distress) or a percentage rating (with 0 percent representing no distress). Results prove INTERCEPTOR excelled at inhibiting deposits and wear. See all the updated performance testing in AMSOIL’s test summary results page.

  • Excellent for all two-stroke snowmobiles
  • Outstanding performance in DFI engines
  • Prevents piston ring & exhaust power valve sticking
  • Protects against wear
  • Low smoke and odor
  • Helps prevent plug fouling
  • Exceptional cold-temperature fluidity (-72°F pour point)

Use AMSOIL INTERCEPTOR Synthetic 2-Stroke Oil in all two-stroke snowmobiles, motorcycles, ATVs, PWCs and where API TC oils are specified.

Polaris® • BRP®/Ski-Doo® (Rotax® E-TEC® engines) • Arctic Cat® • Honda® • Yamaha® • Kawasaki® • Suzuki® • Direct-fuelinjected (DFI), Electronic-fuel-injected (EFI) & Carbureted engines

Use as injection oil or 50:1 premix (2.6 oz. per U.S. gallon of gas). INTERCEPTOR is compatible with most conventional and synthetic two-stroke oils; however, for best performance, mixing oils should be minimized.
