TenEyck Distributing LLC is your premier authorized AMSOIL Dealer in St. George, UT, serving high-performance enthusiasts across the entire Rocky Mountain region. Owned and operated by Mike TenEyck, P.E., we bring a level of technical expertise rare in the industry.

Engineering-Grade Protection
Mike spent 35 years as a Nuclear Engineer for the U.S. Navy, designing and operating nuclear propulsion plants where "good enough" was never an option. Today, he applies those same exacting standards to your engines. We don't just recommend oil; we provide the engineering data to prove why AMSOIL synthetics are the only choice for protecting your investment.

Proven on the Track
Our expertise is backed by real-world data. We actively sponsor and support racers in Snocross, Motocross, and the grueling 2,200-mile Iron Dog race. From supporting young champions like Kaden Woodie in the Pro Open classification to the seasoned competitors of the "Old Ladies" snowmobile race in Island Park, our team proves that products like AMSOIL Dominator 2-Cycle Racing Oil deliver superior torque, cleaner valves, and cooler running engines.

Local Service, National Reach
Whether you need a 55-gallon drum for a commercial fleet or a specific quart for your dirt bike, we offer fast shipping and expert advice. While we are based in St. George, UT, our roots in Idaho, Montana, Utah, Nevada, and Wyoming run deep.
