Article C16.2
Fuel Properties Specifications
Chapter: C16
In Simple Terms
F1 fuel must meet strict quality standards to ensure fair competition and engine reliability. The fuel has specific requirements for octane rating (RON 95.0-102.0), energy content (38.0-41.0 MJ/kg), density, and limited amounts of additives like methanol (max 3.0%) and oxygen (6.70-7.10%). These specifications prevent teams from gaining unfair advantages through fuel composition.
- RON (Research Octane Number) must be between 95.0-102.0 to standardize fuel quality across all teams
- Fuel energy content (LHV) is limited to 38.0-41.0 MJ/kg to prevent performance advantages from fuel composition
- Methanol content capped at 3.0% v/v and oxygen content strictly controlled at 6.70-7.10 wt% to maintain consistency
- Fuel density must fall within 720-785 kg/m³ range to ensure predictable performance characteristics
