WHIPPANY, N.J., March 24, 2026 /PRNewswire/ -- Suburban Propane Partners, L.P.

"The opportunity to support NASCAR at more than twenty tracks nationwide reflects both the strength of our partnership and the reliability that propane can bring to large-scale events," said Nandini Sankara, VP of Marketing & Brand Strategy and Spokesperson for Suburban Propane. "From drying the track to fueling concessions and campgrounds, propane helps ensure that race weekends run safely, efficiently, and without interruption."

The addition of the San Diego event at Naval Base Coronado is part of the sport's participation in America's 250th anniversary celebrations, and represents a particularly unique milestone, bringing NASCAR racing to an iconic waterfront military installation. Meanwhile, the Chicagoland Speedway marks another key market where Suburban Propane will continue supporting operations and fan engagement.
