Its all to do with the concepts of volume and weight.
Using a system called Specific Gravity, you can work out how much a set amount of liquid will weigh.
For example. Fresh water has a specific gravity of 1. Its what we base all other liquid weights upon. So 1000 litres of fresh water will weigh exactly 1 metric tonne (1000kg)
Oils generally have a lower specific gravity, all conventional oils certainly do, than water. So they are 0.85, 0.95 etc.
Unleaded Petrol has a specific gravity of approximately 0.72, so 1000 litres of it will weigh 720kg. 1 litre would weigh 72 grams.
The calculation is volume * specific gravity = weight.
Hope this helps.

Oil or gas floats on water, petrol would be the lighter.

Which weighs more a liter of water at 20 C or 1 dm3 piece of ice at -4 C?
A liter of water at 20 C weights more.
What weights a little more than a liter?
A liter is not a unit of weight. A liter is a unit of volume (equal to one cubic decimeter).
How much petrol deos 1.4 liter engine car need?
ask answers.com It depends on how far you want to go. The more petrol, the farther you go.
How does petrol evaporate faster than water?
It is more volatile than water.
What weighs more 1 liter water or 1 kg soil?
Utilizing the fact that the density of water is somewhat less than 1 kg/L at a temperature of 20 degrees Celsius, we are able to deduce that the 1 kg soil weights somewhat more.
One liter of water weighs more than 1 liter of ice?
One liter of water weighs more than 1 liter of ice. This is because water expands when it is frozen, thus the liquid water will have more water compared to the ice.
Does petrol or spirit evaporate faster?
Petrol evaporates faster than water at room temperature. this is because the boiling point of petrol is 95oC and water's boiling point is 100oC. As the boiling point of water is higher than that of petrol, petrol evaporates faster as it achieves its boiling point before water does.
Is water or petrol cheaper?
In the end, logically, water will be cheaper with water covering more than 90% of the earth's surface
What is heavier 1 liter of air or 1 liter of water?
Water because a liter is a measurement of space and not mass. Water occupying 1 liter of space is lots heavier than air occupying 1 liter of space. <><><><><> It depends on density. It is possible, given enough pressure, to have one liter of air weigh more than one liter of water.
What weights more one gallon of water or one gallon of gasoline?
The same
Does using cold air blowers on a car cause the car to use more water?
Abnormally cold air is harder to generate. It is said that a car will use more petrol and/or water to do this. So yes, using cold air blowers will use a little bit more water and/or petrol
What will have more molecules 1 liter of water or 1 liter of ice?
The lower the temperature, the more close the molecules will be. Therefore the will be less molecules in ice than in water. So water will have more molecules per litre.
