Mercedes has completed the homologation sign-off of its Petronas fuel for the 2026 Formula 1 season, as new insights into the certification process have emerged. The delays in final approval prompted the FIA to allow engines to run on products that weren’t officially signed off to the full 2026 fuel regulations. However, the fuel being used was chemically identical to what was planned for the season. Although there won’t be an official document confirming the completion of the homologation process, multiple sources indicate that Mercedes has finished its certification. The process has been challenging for all fuel suppliers, involving rigorous validation with the FIA for compliance with the rules. The advanced sustainable fuel requirements introduced for 2026 have added complexity, with separate checks conducted independently to ensure compliance.
