    Petrol vapour is denser then air, I assume this what you meant?

    Petrol will eventually evaporate given time but the vapour is denser than air so will collect at the lowest point . Having suffered a leaking petrol tank I know how much the boot will continue to stink of fuel after it's fixed, I've washed the boot carpets and left it open for a week now and I think it's almost cleared the pong.
