AMSOIL is the Official Oil of the Ultimate Callout Challenge (UCC), a friendly annual competition between owners and builders of some of the biggest and gnarliest diesel-powered American hot rods. Competitors are required to complete three events: dyno, sled pull and drag race, with winners crowned in each event. Individual event scores are combined to determine an overall champion.
The winning turbodiesel truck at the 2024 AMSOIL Ultimate Callout Challenge was built by Team AMSOIL racer Ken Bruner, a mechanical engineer who designs medical devices when he’s not racing turbodiesel trucks with his company, Capital Diesel Performance.
