Fuel Density Verification

In Simple Terms

F1 fuel must have consistent density (thickness/weight) throughout the season. Teams can't use fuel that's more than 0.15% different from what was approved before the season started. This prevents teams from gaining an unfair advantage by using different fuel mixtures.

• Fuel density is checked against the baseline figure recorded during pre-season approval
• The fuel can only vary by a maximum of 0.15% from the approved density
• This rule ensures all teams use fuel with consistent properties throughout the season
• Density variations could affect engine performance and fuel consumption, creating competitive advantages
