AMSOIL Powers USAC Sprint Week in Indiana  

Every summer, Indiana transforms into the epicenter of dirt track sprint car racing as the USAC AMSOIL Sprint Car National Championship rolls through the state for Sprint Week—a high-octane spectacle that captures the heart of grassroots American motorsports. In 2025, the tradition continued with even more horsepower, history and heartbreak than ever before. 

Eight Tracks, 10 Nights, One Epic Showdown 

Sprint Week is a grueling test of endurance, skill and mechanical grit. Over 10 nights, drivers compete in eight races across eight legendary Indiana dirt tracks, each with its own quirks and challenges. From the tight turns of Kokomo Speedway to the high banks of Lawrenceburg, the series pushes both racer and machine to their limits. 

This year, the series made history by adding a new premium track to its lineup: the iconic dirt track at the Indianapolis Motor Speedway (IMS). The inclusion of IMS not only elevated Sprint Week but also drew national attention to the series.

Driving Performance On and Off the Track 

It is no secret that commitment to motorsports runs deep at AMSOIL, fueling racers with high-performance synthetic lubricants engineered to win races. That passion and commitment is on full display in the USAC AMSOIL Sprint Car National Championship series and Indiana Sprint Week.  

Each year, AMSOIL chooses to back a number of standout drivers within our title series, each with their own style and story. The 2025 AMSOIL sponsored racers include:  

• Justin Grant, a former Sprint Week champion and perennial fan favorite who entered the week second in the season standings. His aggressive yet calculated driving style made him a top contender with a win at the IMS Track – until disaster struck, ending his run. 

• Robert Ballou, sitting sixth in points, brought his trademark intensity and experience to the track, always a threat to steal a win on any given night, including a win in Putnamville on July 25.  

• C.J. Leary, piloting for Team AZ, entered the week ninth in points. A smooth driver with a knack for consistency, Leary aimed to make his mark on the week. He succeeded with a win at the Circle City track on Wednesday.   

• Gunnar Setser of KO Motorsports, twelfth in points, represented the next generation of sprint car talent, showing flashes of brilliance throughout the week. 
• Ricky Lewis, ranked 22nd, may not have a chance at the title this year, but his grit and determination always make him a crowd favorite. 

Triumph and Tragedy: The Justin Grant Story 

Sprint Week is as much about resilience as it is about racing. For Justin Grant, 2025 was shaping up to be a career-defining run until a devastating crash upended his campaign. The incident, which occurred during a heated battle for position, left Grant with injuries requiring surgery. Grant returned with aspirations to race on Tuesday but ultimately decided against continuing, dashing any hope reclaiming the Sprint Week crown. 

The racing community rallied around Grant, whose toughness and sportsmanship have made him a respected figure in the paddock. His absence was felt deeply in the remaining races and serves as a reminder of the risks each day on the track brings.

The Spirit of Sprint Week 

Despite everything, Sprint Week 2025 delivered unforgettable moments: photo finishes, dramatic comebacks, and the roar of engines echoing across the Indiana landscape. Spectators showed up with their trademark gusto, cheering on their favorite drivers.  Teams faced the grueling week with tireless dedication, keeping each sprint car in racing shape.  

For AMSOIL, the week was a testament to the spirit of the partnership with USAC and the Sprint Car series. It’s not just about the sport – it is the racers, fans and organizers who make the series and Sprint Week special. The heart and hustle that defines sprint car racing was evident with every race. 

Looking Ahead 

As the dust settles on another thrilling Sprint Week, one thing is clear: the spirit of competition is alive and well in Indiana as USAC AMSOIL Sprint Car National Championship series and Indiana Sprint Week continue to grow, evolve and inspire.
