The fast time he did would have taken around 20 kilos, as Jerez uses about 2.5 kilos per lap. Later he was doing 1:26s on something like a 25 lap run I think. The difference in lap time is such that he would have been carrying something around 150 kilos of fuel with a corresponding 5.5 to 6.0 second deficit to his fastest time. That tallies reasonably well as a back of the hand calculation.
Speculating about other fuel loads or engines being turned down (highly unlikely because there is no point at all to it) really is bunkum.
Pirelli said there was a 3 seconds difference between super soft and hard tyres, so without knowing in which tyres he was during those long run all we talk is pure speculation.
