Gasoline and diesel quality improvement programs launched recently in Europe and the USA foresee some measures for this decade, including the development of sulfur-free fuels, with an increasing cutting edge compatible with the superior quality of those products. Based on this scenario, Petrobras has focused on developing new fuels, biofuels, and lubricating oils to make domestic products more competitive compared the European and American ones.
