the whole temperature thing is unscientific, and any advantage caused by cooler fuel would only last a lap or two as it heated up to match the boiling hot car's temperature.
what really stinks about the whole thing is how perfectly coincidentally the only cars pulled about this are the ones directly in front of Lewis. Nakajima's fuel also gave readings of fuel more than 10C cooler than ambient, but is not under suspicion. is this only because only points-scoring cars are investigated if this happens?
so if all 22 cars gave dodgy fuel readings, would only the top-8 be investigated?
and even if these 3 cars are thrown out from the Brazilian result, it doesn't in any way mean that Lewis will automatically be elevated to 4th place, it's up to the stewards if they move the next guy up or not. so Autosport have suggested that the most likely outcome will be that the 3 cars will be DQ'ed, but Lewis will remain in 7th, thus not affecting Kimi or Lewis.
RIP Jules, never to be forgotten. #KeepFightingMichael
