Location of lubricating oil tanks

Chapter: C7

In Simple Terms

Oil tanks must be positioned in a specific area of the car's chassis, between two defined longitudinal points (X F=0 and X DIF=150), and cannot extend beyond the widest part of the driver's safety cell. This ensures they stay in a safe, contained location within the car's core structure.

  • Oil tanks must be located between X F=0 and X DIF=150 on the car's length
  • Tanks cannot extend outboard beyond the lateral extremities of the Survival Cell
  • This rule protects the structural integrity and safety of the driver's compartment
  • Placement restrictions ensure consistent fuel system packaging across all teams
Official FIA Text

All oil storage tanks must be situated between X F=0 and X DIF=150, and must be no further outboard than the lateral extremities of the Survival Cell.
