Non-Sustainable Additive Package Allowance

In Simple Terms

F1 fuel can include special additives and denaturants (chemicals that make fuel unsuitable for other uses) up to a maximum of 1% of the total fuel weight. These additives must serve a genuine purpose related to either improving fuel performance or preventing misuse.

• Maximum 1.0% by mass of non-sustainable additives and denaturants allowed in blended fuel
• All additive components must have a rational connection to additive or denaturant functions
• Non-sustainable additives are separate from sustainable fuel components regulated elsewhere
• Denaturants prevent fuel from being used for unauthorized purposes outside of racing
