snippet from BBC, FIA has all but said this season is in the books from what they are saying, little info on the fuel here.

Excluding the Williams and BMW Sauber cars would have risked turning one of the most exciting championship finales in F1 history into a farce.
But the stewards had the power to disqualify them, even though the advantage conferred would have had no bearing on the title race.
The total advantage for each car over the race distance was almost certainly no more than a second.
The FIA said Heidfeld's fuel was 13C lower than ambient at his first stop and 12C lower at his second.
Kubica's varied by 14C, 13C and 13C at his three stops, while Rosberg's was 13C and 12C out at his two stops.
Filling the car with cooler fuel can give a performance advantage.
Cooler fuel is denser, so either it can mean it takes slightly less time to refuel the car or marginally more can be added in the same time.
And it would give a slight power advantage for about three laps before it returned to ambient temperature out on the track.
There is some form of precedent not to exclude the cars.
In 1995, the Benetton-Renault of Michael Schumacher and the Williams-Renault of David Coulthard were initially disqualified from first and second places in the Brazilian Grand Prix because their fuel did not conform to samples approved by the FIA.
But a week later the FIA reinstated the drivers' points but docked the teams their constructors' points.
In that case, though, no advantage was gained by the irregularity.
