I have it in my head that petrol has a density of around 70% that of water. One litre of petrol weighs 700g, ish.
Anyway somebody emailed me to ask if a higher octane fuel is heavier... I don't know. Might be because of the higher proportion of hydrocarbons or something .
Anybody?
It's very variable Have a look at these

The fuel is stored well underground where the temperature stays near constant.
may be a problem in Iceland though. The country, not the shop.

The temperature underground stays constant anywhere - if you go deep enough. Hell fire rools.
Actually there is a slight variation see:
But yes it won't make a blind bit of difference to a car only taking on only
20 lts.(Note the smiley)
Slatts
Usually it is denser: 750g vs 740g ish. Leaded petrol was less dense.
Keeps the fuel mixture right though init?
As the day and the fuel warm up the car breathes in less air cos its less dense. And adds less fuel cos its less dense too!
