Is there any liquid that has lower density than petrol.
one more point : it should not be a fuel.Is there any?

Borek, I fear this forum is slowly mutating you into a physicist!

thanks.
But liquid helium does'nt exist in liquid form in room temperature.
Is there any other liquids less dense than petrol and exists as liquid in room temperature.

You are moving goalposts now

And I am not convinced you told us all. What will be the next condition? And what does it mean "not a fuel"?

Not that I can think of any substance that is liquid at RTP, has a density around 0.7 g/mL and is not a hydrocarbon.

How about Hydrogen cyanide? Boiling Point 25 deg. Celsius, Density 0.68 g/cm^3. Not used as a fuel as far as I know although it is highly inflammable. It is used both as a reactant and a solvent in the Gattermann synthesis.
