Oh well, just blew a win because of CC...Oval race, with only one yellow. Used the command "Pitstop: fuel to the end". It added 12 liters, when I would have needed like 25. That's a wrong calculation of about 14 laps !!! I did add extra laps of fuel in CC options so it was off by maybe 16 laps. You can't add extra 20 laps of fuel in the CC options, just to make shure you finish the race, that is just non sense...
