Light crude oil:

Light crude oil is liquid petroleum that has a low density and flows freely at room temperature.

it has a low viscosity, low specific gravity and high api gravity due to the presence of a high proportion of light hydrocarbon fractions.

it generally has a low wax content.

Light crude oil receives a higher price than heavy crude oil on commodity markets because it produces a higher percentage of gasoline and diesel fuel when converted into products by an oil refinery.
