No the gravity can change due to temperature & density of the fluid... oh sh#t i'm attempting to use my brain on a Monday morning & it hurts But the difference would be tiny..

Fraid different liquids have different weights, hence the reason oil and most of its derivitives float on water, its all about S.G. (specific gravity) IIRC oil is around 0.81 where as water is 1, thus 1 litre of oil is lighter than a litre of water, weird eh.

Ok I can accept that liquids can be different weights and I should have know that already but it is still early
But what about petrol can different brands of petrol be different weights and burn longer etc that they are accusing Ferrari of???
I thought there were only a handfull of refinaries that produce all the petrol and just badge it differnetly, Surely Shell can not be that more advanced than BP or ESSO etc that they can make petrol lighter and burn slower than anyone else.

The teams try everything to keep the car as light as possible (then they add ballast in relevant places to make it a) handle and b) pass the regs)
They even use Helium in the tires rather than plain air as it is lighter and reduces the un sprung weight!

Cant remember exactly what the air is they use but its not to do with outright weight savings. It's to do with vapour (water) and making sure there isnt any as this exacerbates the problem of pressure changes when the tyre is being used IIRC.

I think you will find they use pure nitrogen.

I think helium would work in the case of a racing car because....well, how long are the tyres in use? 1/2 an hour, an hour at most. Doesn't give it much time to find ways to escape.
