What Makes a Crude Oil âLight?â Crude can be classified as âlightâ or âheavy,â a characteristic which refers to the oilâs relative density based on the American Petroleum Institute (API) Gravity. This measurement reflects how light or heavy a crude oil is compared to water. If an oilâs API Gravity is greater than 10, it is lighter than water and will float on it. If an oilâs API Gravity is less than 10, it is heavier than water and will sink. Lighter crude is easier and less expensive to produce. It has a higher percentage of light hydrocarbons that can be recovered with simple distillation at a refinery.
