What kind of crude oil is better? (more expensive)

sweet crude oil
sour crude oil
salty crude oil
bitter crude oil
Sweet crude oil contains small amounts of hydrogen sulfide (in contrast to sour crude oil). Low-sulfur crude oil is in high demand as it is used to produce high-quality gasoline without the need for expensive processes of removing sulfur impurities. The term "sweet" originates from the fact that a low level of sulfur provides the oil with a mildly sweet taste and pleasant smell. Nineteenth century prospectors would taste and smell small quantities of oil to determine its quality.
