Only the fuel designated for each category and provided by the organiser may be used by all the competitors during the Events. The specifications may be provided on request to the organiser.

The official fuel supplier will always deliver the fuel in drums for European and overseas Events. All the competitors must only use the fuel supplied by the official fuel supplier.

The maximum quantity of stock fuel authorised per car in each garage is 400 litres. This fuel must be stored near the door, on the paddock side and an extinguisher must be permanently placed near the fuel drums and/or the temporary tank. Pumping from supply drums, transfer to autonomous tank and this filling must be made using a temporary tank. No handling of fuel is permitted in the pit except with this temporary tank. The only possible exception, subject to prior written request and approval by the Technical Delegate, is the control of the tank capacity of the car with precisely calibrated containers.
