EN 590 Gas Oil specification table explained. Diesel EN590 10 PPM is a type of diesel fuel that meets the European standard EN590 for automotive diesel oil. The 10 PPMâ?? refers to the maximum sulphur content of the fuel, which is 10 parts per million (ppm) or less. Low-sulphur diesel fuels such as EN590 10 PPM are required in many parts of the world to meet emissions regulations and reduce air pollution. The lower sulphur content in the fuel allows diesel engines to operate more efficiently and with less emissions of harmful pollutants such as particulate matter and nitrogen oxides. EN590 10 PPM diesel fuel is commonly used in modern diesel engines, including those in passenger cars, trucks, buses, and heavy equipment. It is typically available at fuel stations that offer diesel fuel, and is used in many countries throughout Europe and around the world. Contact us for Specification Sheet.
