Making the world better, one answer at a time. West Texas Intermediate (WTI) crude oil is of very high quality and is at refining a larger portion of gasoline. Its API gravity is 39.6 degrees, which makes it a light crude oil, and it contains only about 0.24 percent of sulfur (making a sweet crude oil).Brent Blend is actually a combination of crude oil from fifteen different oil fields located in the North Sea.It is still a light crude oil, but not quite as light as WTI, and it contains about 0.37 percent of sulfur (making it a sweet crude oil, but again slightly less sweet than WTI).Brent blend is good for making gasoline and middle distillates. WTI is more expensive than Brent.t is still a light crude oil, but not quite as light as WTI, and it contains about 0.37 percent of sulfur (making it a sweet crude oil, but again slightly less sweet than WTI).
