The country’s fastest racing series is back for another year as the 2026 SEAOIL Radical Challenge Philippines gets underway at Clark International Speedway (CIS) this August 21/23. Now entering its fifth season, the championship will feature four rounds at Clark and Batangas Racing Circuit (BRC), with FUCHS Lubricants Philippines joining as its new Official Lubricant Partner.
Last season delivered dramatic title battles in both the SR3 and SR1 Challenge Cups, with both championships decided in the closing rounds. Defending champions are expected to return as they look to retain their crowns, while familiar rivals and new drivers are set to make this year’s grid even more competitive.
The 2026 calendar opens at CIS before heading to BRC for back-to-back rounds in September and October. The championship then returns to Clark for the season finale in November.
2026 SEAOIL Radical Challenge Calendar
Round 1 | August 21-23 (Clark International Speedway)
Round 2 | September 25-27 (Batangas Racing Circuit)

Each round will once again feature Practice and Qualifying followed by three 30-minute sprint races.
Performance levels have steadily risen in the series, with lap records falling throughout 2025 and overall pace improving across both classes. Drivers will continue to race on SEAOIL Extreme-97 fuel, while the new partnership with FUCHS will see the championship use products from its TITAN automotive lubricant range.
This covers engine oils, gear and transmission fluids, and other specialist lubricants, extending to the fully synthetic TITAN RACE competition line. Founded in Mannheim, Germany in 1931, FUCHS is the world’s largest independent lubricant manufacturer and supplies more than 10,000 lubricant solutions across over 50 countries.

“Partnering with Radical Philippines is a natural fit—two brands built on precision engineering and a relentless push for performance. We’re excited to fuel the next generation of Filipino racing talent with lubricants trusted on tracks worldwide,” said Roland Metelmann, Managing Director of FUCHS Lubricants Philippines.
Edward Cruz, Head of Fuels Marketing at SEAOIL Philippines, highlighted the growth of the championship as it reaches its fifth season.
“As we open the fifth consecutive season of the SEAOIL Radical Challenge Philippines, we take pride not only in how far the championship has come, but in the community that has grown with it. What began as a vision to elevate Philippine motorsport has become the country’s fastest racing series and a platform where talent, technology, and passion converge,” he said.
The opening round of the 2026 SEAOIL Radical Challenge Philippines takes place at Clark International Speedway on August 21/23.
The 2026 SEAOIL Radical Challenge Philippines is supported by SEAOIL Philippines, Inc., FUCHS Lubricants Philippines, Bank of the Philippine Islands, Tieline, and John Barbers.
