Obligations of PU Manufacturers Regarding Fuel and Oil Suppliers

In Simple Terms

Power unit manufacturers must tell F1 who their fuel and oil supplier will be within 90 days of signing up. They can switch suppliers later if needed, but there are strict rules about what technical information they can share with their suppliers, especially details about how the engine burns fuel and manages air flow.

• PU manufacturers must nominate their fuel and oil supplier within 90 days of registration
• Suppliers can be changed at any time if the required conditions are met
• Sensitive engine technical data about combustion and gas exchange cannot be freely shared with suppliers
• Information sharing restrictions protect competitive advantages in engine development
