Yes, it said he was fuelled for 25 laps!... a further 25 laps! Trulli had more fuel on board, about 9 laps obviously! The reason why he pitted so early with that amount of fuel still onboard, was because he was losing time with his worn tyres!
The thing is, F1 Digital aren't told how much fuel the cars have at the start, so there is no way they can say how much laps they are fueled up for. They can only tell what goes in!
Make sense?!
