What is the specific gravity of gasoline?

Depending on the nature of its composition, the specific gravity of gasoline can vary between 0.71 and 0.77. The specific gravity of common vehicular gasoline is approximately 0.74.

Gasoline, also known as petrol, is the most common fuel used in modern vehicles. It consists of several organic compounds, and is obtained from petroleum through a process called "fractional distillation."

Specific gravity is a dimensionless parameter that represents the ratio of the density a substance to the density of water at 4 degrees Celsius. The specific gravity of gasoline is less than 1, which means that it has a density less than water and is lighter than water.
