Fuel Composition Requirements

In Simple Terms

F1 fuel must follow strict composition rules to ensure fairness and safety. The fuel can contain limited amounts of certain compounds like aromatics and olefins, but is banned from containing substances that could react explosively on their own. These rules prevent teams from using specially-engineered fuels that could give them an unfair performance advantage.

• Aromatics limited to maximum 40% by weight
• Olefins capped at 17% and diolefins at 0.51% maximum
• Styrene strictly limited to 0.1% by weight
• Any self-reactive substances (exothermic without external oxygen) are completely prohibited
