Hello everybody. I am new to watching Virgin Australia Supercars and I keep hearing the announcers refer to a minimum fuel drop volume for the race. Is this volume the same for all races? What is the capacity of their fuel tank? Do all cars have same tank size? Is the tank size the same for all races? Does the minimum amount always take two stops to complete or is the two stop rule unrelated? This all seems so important to strategy but these announcers arent explaining much about it. Thank you for any and all help!
