Auxiliary Oil Tank Prohibition
Chapter: C5
In Simple Terms
F1 teams are only allowed to use one main oil tank to store oil. They cannot use extra oil tanks hidden elsewhere on the car. Small amounts of oil that naturally collect in other parts (like catch tanks) are okay, but intentional storage in additional tanks is banned.
- Only one oil tank is permitted per car
- Additional or auxiliary oil tanks are strictly prohibited
- Incidental oil accumulation in catch tanks is acceptable
- Oil storage must comply with C5.22.3 specifications
Official FIA Text
The use of an Auxiliary Oil Tank, or other forms of oil storage other than the single oil tank defined in C5.22.3 is not permitted. Accumulation of oil in other volumes (such as catch tanks) may be deemed acceptable only if incidental.
