INTERCEPTOR Field Trial Results

During the winter of 2015/16, INTERCEPTOR was tested in the three top makes of snowmobiles. Each sled was added to the rental fleet of a different outfitter in the Eagle River, Wis., area and placed into service. Following the season, the sleds were disassembled and examined for wear. Results reveal INTERCEPTOR prevented piston ring sticking and piston scuffing, (see below) while the exhaust power valves contained no abnormal deposit buildup and did not stick.


- Excellent for all two-stroke snowmobiles
- Prevents piston ring & exhaust power valve sticking
- Exceptional cold-temperature fluidity (-69°F pour point)

- Outstanding performance in DFI engines

- Protects against wear

- Low smoke and odor
