The increasing concern regarding air quality improvement has guided the environmental legislation to establish severe restrictions goals for vehicular pollutants reduction. The ongoing search for cleaner-burning fuels does not necessarily result in appropriate fuel performance. Such restrictions directly impact the refining scheme of diesel fuel production and reflect on changes in its chemical composition. The severe refinery hydro-processing being introduced to remove sulfur, also reduces surface active compounds and antioxidants, potentially changing the final properties of the low sulfur diesel oil produced. The S10 diesel fuel (10 mg/kg of sulfur) was released in Brazilian Market in January, 2013 to substitute the S50 one (50 mg/kg of sulfur), necessary for the new engines with technologies CONAMA P7 and PROCONVE L6 (SUV - sport utilities vehicles and pickups). In this work, the S10 diesel fuel performance, in terms of emissions, stability and detergency was evaluated. The influence of FAME blending and additives was also studied. Engine tests Peugeot XUD9 and Peugeot DW10 were used as tools for assessing the tendency to form deposits in fuel injectors. The test results confirmed the adequate performance of these low sulfur diesel formulations.
