What does sulfur do in fuel? Sulfur is a natural component in crude oil that is present in gasoline and diesel unless removed. Sulfur in gasoline impairs the effectiveness of emission control systems and contributes to air pollution. Reducing the sulfur content in gasoline enables advanced emission controls and reduces air pollution. What fuel has the most sulfur? Higher sulfur content than 0.5 wt % results in crude oil being known as 'sour crude oil'. Most of this sulfur content in crude oil occurs in molecular form attache to the hydrocarbons. Small amount is contained as elemental sulfur and in...
