Petronas Faces Critical Timeline Push to Certify Mercedes F1 Fuel for 2026 Season
Petronas is working urgently to secure official homologation for the sustainable fuel that will power Mercedes-affiliated teams throughout the 2026 Formula 1 season. The fuel certification process has become more complex following changes to testing and verification procedures that were implemented following the previous year.

The clock is ticking for Petronas as the Malaysian energy giant races to complete the certification process for its sustainable fuel blend destined for Mercedes-powered F1 teams competing in the 2026 season.
The certification landscape has shifted considerably compared to previous years. Historically, fuel testing and homologation duties fell to a British laboratory that maintained FIA affiliation, where manufacturers could submit samples for straightforward compliance verification against the sport's technical rulebook.
However, this streamlined approach is no longer in place, creating additional hurdles for Petronas to navigate as it seeks the necessary sign-off for its fuel formulation ahead of the 2026 campaign.
