Article 3.9
Changes of fuel and oil suppliers
Chapter: APPENDIX C5: HOMOLOGATION AND DEVELOPMENT OF POWER UNITS, FUEL AND OIL FOR 2026-2030
In Simple Terms
F1 teams can switch to different fuel and oil suppliers during a season, but only if the reason is business-related (like a sponsor deal) rather than to gain a performance advantage. The FIA wants to prevent teams from constantly changing suppliers just to find faster fuel or oil.
- Teams are permitted to change fuel and oil suppliers during the season
- Changes must be for commercial reasons (sponsorships, business deals) only
- Changes cannot be motivated by seeking performance improvements
- The FIA monitors supplier changes to ensure compliance with this rule
Official FIA Text
Changes of fuel and oil suppliers will be accepted, provided such changes are intended for commercial and not for performance reasons.
