Oxidant Source

In Simple Terms

F1 engines can only use regular air from the atmosphere to burn fuel—no special oxidants or additives are allowed. This ensures all teams use the same basic ingredient, keeping the competition fair and preventing teams from gaining unfair advantages through exotic fuel mixtures.

• Only ambient air (regular atmosphere) is permitted as the oxidant source
• No chemical oxidants, additives, or special compounds can be mixed with fuel
• This rule applies universally to all teams to maintain competitive fairness
• The regulation prevents teams from gaining technological advantages through non-standard fuel mixtures
