Sulfur

Sulfur is found in refined petroleum products, including gasoline. This is because crude petroleum is mainly composed of hydrocarbon and other components, including organic and inorganic sulfur containing compounds. Sulfur is the third most common element in crude petroleum after carbon and hydrogen. Crude petroleum with high sulfur content is more complicated and more expensive to refine. Hence, gasoline still contains sulfur.

Sulfur in fuel escalates metal corrosion in the engine, the fuel system and the exhaust system. In addition, it increases vehicles’ sulfur oxide emissions. For these reasons, sulfur content in fuels, including gasoline, should be limited.

The SGS WWFS gasoline sampling results in Denmark indicated good compliance with the national legislation and EU Fuel Qualit
